The latest addition to Schaffner’s compact industrial FN3280H EMC filter range has been introduced to meet demands for higher power from machinery and power cabinet manufacturers.
The latest addition to Schaffner’s compact industrial FN3280H EMC filter range is rated at 200A at 50C, and has been introduced to meet demands for higher power from machinery and power cabinet manufacturers. The FN3280H filter range now has nine models rated from 8 to 200A and all offer three-phase-plus-neutral sum filtering for potentially noisy machines connected to low-voltage electricity networks, which may also supply domestic or commercial users. In these environments Class A and occasionally even Class B EMC filtering is required.

To simplify system design the filter currents of all models have been aligned to commonly available fuse protection values and outstanding low leakage currents of less than 1mA are attainable in four-wire connection mode.

The new FN3280H-200-40 offers outstanding filter performance in a very compact package and does not derate under full-load operating conditions.

Connection is made via Schaffner’s proprietary ‘touch safe’ terminal blocks that meet EN60204-1 to provide maximum safety for installers, inspectors and operators.

Three-phase/four-wire filters are now a standard product and available off the shelf.

The FN3280H range of filters is ideal for machine tools with up to 12 driving axes with 10 to 20m of motor cable each likely to be operated in mixed domestic environments and will allow manufacturers to comply with Class A or even Class B filtering.

FN3280H filters also improve the immunity and reliability of the entire system by also protecting the machine against incoming conducted interference from the operating environment.

This additional protection ensures maximum productive up-time and lowers maintenance costs.

‘We have introduced this new 200A filter in direct response to our customers’ needs’, comments Andy Kotas, Marketing Manager of Schaffner.

‘Machine tool and power cabinet manufacturers are always under pressure to provide more power, frequently in restricted spaces’.

‘Our very compact, safe, easy to use, high performance filters are an ideal solution’.

Typical applications include manufacturers of machinery, machine tools, and process automation equipment, energy conservation devices and regenerative motor drives, power cabinets, premium three-phase-plus-neutral power supplies and UPS and solar power technologies.

New compact low-profile film-type choke coils help designers suppress common-mode noise on high speed differential signal lines, without distortion.
For designers seeking to suppress common mode noise on high speed differential signal lines, without distortion, Murata has announced the DLP0NS Series of compact low-profile film-type common-mode choke coils. Taking advantage of Murata’s advanced microfabrication film technology and superior ferrite materials, the DLP0NS coils are ultracompact and provide accurate transmission of high-speed differential signals. Common mode choke coil circuits are increasingly being used for the effective suppression of common mode noise without distorting the waveform of high-speed signals.

The DLP0NS chip coils measure just 0.85 x 0.65 x 0.45mm in profile, with a tight +/-0.05mm dimensional tolerance, making them ideal for today’s high speed portable products, particularly those incorporating USB2.0, IEEE1349 or LVDS protocols, as well as in HDMI and DVI applications.

Impedance characteristics of devices in the series are specified at 67, 90 or 120ohm at 100MHz.

Rated current is 110, 100 and 90mA, respectively, and rated voltage is 5V DC.

Insulation resistance is quoted at 100Mohm minimum, and DC resistance is 2.4, 3 and 3.8ohm +/-25%, respectively.

Operating temperature range is -40 to +85C.

Specific applications for Murata’s chip common-mode choke coils include noise suppression in devices using the IEEE1394 bus interfaces, connecting computers and audio/video systems with other peripheral equipment.

Other applications include LVDS lines of notebook computers and LCDs, and USB lines of PCs, notebook computers, digital stills cameras and digital video cameras.

The DLP0NS common mode choke coils are available now in production volumes and can be supplied bulk or taped and reeled.

Abacus Polar has added a new common mode filter specifically designed to address the challenge of clearing EMI off high speed data and signal lines without distortion. Also new is a series of winding type chip inductors, for audio/video, computer, mobile phone and industrial applications alike. The TDK ACM2012 ferrite chip common-mode filter series from Abacus Polar is aimed at audio, video and other high-speed differential mode transmission, and causes almost no distortion to high-speed signals.

It is available in four specifications, including versions optimised for USB2.0 (480Mbit/s) and IEEE1394 (400 and 100Mbit/s).

The ACM2012 series is targeted at audio-video equipment that uses HDMI.

The high precision formation technology and the automatic coiling and terminal connection technologies of TDK micro core units, achieve a coupling coefficient between coils of more than 0.99.

While improving the removal of common-mode elements accumulated on signal lines, the deterioration of signal waves by differential mode impedance has been reduced to one of the lowest levels in the industry.

The products satisfy the strict HDMI TDR standard.

The outstanding performance of the ACM2012 is achieved within a form factor believed to be smaller than any comparable common-mode filter, with a footprint of just 1.3 x 2.0mm.

The device is fully RoHS compliant.

The GLF Series of chip inductors is magnetically shielded and available in the case sizes GLF1608 (0603), GLF2012 (0805) and GLF2518 (1008) as well as the low-profile versions GLF201208 and GLF251812.

The GLC2518 (1008) Series is a power inductor with a very small case size for applications which need a high current - like AC/DC inverters or small DC/DC convertors.

The X2Y is an integrated passive component, providing three capacitors in one device, thereby dramatically reducing the total number of standard passive components required
With the twin advantages of reduced component count and high mechanical integrity, UK-based component manufacturer Syfer Technology has released an extended range of RoHS-compliant X2Y three terminal capacitors. Aimed at decoupling and EMI suppression tasks in a variety of general purpose and function specific applications, Syfer’s X2Y range is ideal for designs where space is at a premium. The X2Y is an integrated passive component, providing three capacitors in one device, thereby dramatically reducing the total number of standard passive components required.

A reduced component count can lead to significant cost savings, reduced assembly time and higher product reliability.

In addition, these X2Y capacitors are optionally available with Syfer’s innovative flexible terminations, called FlexiCap.

This technology, unique to Syfer, is designed to reduce the risk of mechanical damage, such as cracking, during handling and assembly processes.

FlexiCap is applied to the termination areas underneath the nickel barrier coating and tin-plated finish.

The inherent flexibility of the material provides greater scope for the device to accommodate the mechanical stresses typically present in PCB assembly operations, and also in the field, particularly for portable products.

One of the most important features of X2Y dielectric technology is that it exhibits extremely low self-inductance, making it particularly suitable for high frequency decoupling applications.

With the rapid growth in high speed communications and multimedia technology, particularly for broadband circuits, these devices are in increasing demand for both decoupling and suppression.

Syfer’s range of balanced line, three terminal X2Y chips provide simultaneous line to line and line to ground filtering.

Delivering both differential and common mode filtering, in a compact package, they are ideal for balanced line, EMI suppression in DC motors in a wide range of automotive, telecomms and industrial applications.

The filter devices are well suited for use in sensors (including Hall effect), filtered connectors and fibre optic components, crystal circuits and LED modules.

Syfer’s X2Y filter capacitors are ideal for CANbus applications, as well as for audio amplifiers and micropower instrumentation amplifiers.

There is growing interest from customers in the military and medical sectors; and the devices can also be used in general signal line filtering applications, particularly in multiple-PCB based systems and to provide bulk capacitance for switching power supplies.

The chips are available in various combinations of capacitance values, from 10pF up to 1.2uF, with rated voltages of 25, 50 or 100V, in case sizes from 0603 to 2220.

Syfer’s balanced line X2Y and three-terminal chip ranges are fully RoHS compliant, and already in volume production at its upgraded, state-of-the-art, Norwich, Norfolk, UK facility.

The devices are currently on a 6-week lead time, and any quantity of devices can be ordered from samples through to high volume, for delivery loose, or taped and reeled for automated assembly systems.

Pricing depends on chip size and quantity, but in general range from GBP 0.03 to GBP 0.40 each.

Syfer has invested heavily in developing RoHS compliant devices across its entire product range.

Its expanding range of RoHS compliant EMI filters includes three-terminal EMI chips, high current EMI chips, X2Y balanced line chips and 1206 size pi-filters.

The MEA2010PE series of multilayer chip EMI filter arrays are the world’s first noise countermeasure products for use in mobile terminals that can receive terrestrial digital broadcasts.
TDK has developed the MEA2010PE series of multilayer chip EMI filter arrays, the world’s first noise countermeasure products for use in mobile terminals that can receive terrestrial digital broadcasts. Production of the new filter arrays is scheduled to begin this month. Terrestrial digital television broadcasts for mobile terminals (one segment broadcasts) are scheduled to begin in Japan in April 2006.

Terrestrial digital broadcasts are also progressing in Europe and other regions.

In conjunction with these developments, development and use of television tuners designed specifically for cellphones and notebook PCs is increasing rapidly.

When such tuners are used in cellphones, in addition to the communications band (800MHz-2GHz), a broadcast band (470-770MHz) is also used, and as a result, noise countermeasures are crucial in device design and miniaturisation.

TDK’s new filter arrays respond to these market developments, providing cutting-edge noise countermeasures with a focus on terrestrial digital broadcasts and a compact package just 2.0 x 1.0 x 0.7mm in size.

Because video data is the core component of terrestrial digital broadcasts, it is essential to reduce noise in the 470-770MHz band while minimising any deterioration of the circuit waveform quality.

The new array filters use optimal materials and pattern designs in the pursuit of exceptional noise countermeasures for terrestrial digital broadcasts.

The four product lineup can be used in terrestrial digital broadcast tuners and as an effective noise countermeasure in a variety of applications that use the 470MHz to 2GHz band.

A new range of EMI suppression products manufactured from Fair-Rite’s 46 material are environmentally green, economically lean and electromagnetically clean.
Now available from Dexter Magnetic Technologies is Fair-Rite’s 46 material EMI suppression products. This material is aimed at reducing costs without losing performance. Products manufactured with this material are environmentally green, economically lean and electromagnetically clean.

During the last 5 years ferrite manufacturers have experienced dramatic price increases in the cost of nickel oxides.

The increase in demand from the Chinese metal industry has caused a worldwide shortage and price increases.

To combat this scenario Fair-Rite has developed this new material that maintains a very acceptable performance level compared to its 43 material.

This material has no nickel oxide content, is RoHS compliant, cost effective and with a similar impedance and frequency range to 43 material.

Typical impedance of a 43 material cylindrical cable core with dimensions of 25.9 x 12.8 x 28.6mm is 235ohm at 100MHz; the same size core in 46 material is rated for 210ohm at 100MHz.
