A new fourth-generation ultraminiature automotive relay for motor applications is 28% smaller than its third-generation predecessor.
Fujitsu Components Europe has released its fourth-generation ultraminiature automotive relay for motor applications. The new relay is a slim device that is 28% smaller than its third-generation predecessor, the FTR-P3. The FTR-G1 is a PCB-mounting 1 form C single relay that can handle 25A loads at 14V DC for high-inrush applications such as power window and gate lifts, automatic sliding doors, door locks, adjustable seats and intermittent wipers.

Because the FTR-G1 is used in modules typically mounted within the passenger compartment, its maximum acoustic noise level is a low 60dB.

The relay measures a compact 13.7 x 6.6 x 13.5mm.

It features a unique pin layout that contributes to the relay’s reduced size while also retaining sufficient isolation distance for simplified PCB layout.

Coil power is 640mW.

Fujitsu developed an efficient, magnetic circuit to minimise the relay’s size, weight and power consumption.

A highly conductive spring, along with high-temperature moulds and coil wire, increases heat resistance.

A simple, two-piece assembly process requires no insertion moulding to reduce assembly costs and the introduction of contaminants.

The FTR-G1 is RoHS-compliant and available immediately from stock.
