Japanese electronic components company FCL Components has released a small, low-power, automotive-grade, PCB-mounted relay, the FBR53-LE.

The relay is more than 2 mm shorter than others in its class, enabling more compact designs, according to the company.

The FBR53-LE is a 1 Form U (Form A with twin contacts) relay that measures 15.7(L) x 12.3(W) x 14(H) mm, with a volume of 2,704 mm³. It has a maximum carrying current of 54 A for 1 hour, and a maximum inrush current of 200 A. It has a contact rating of 14 VDC, 40 A, and a nominal coil power of 640 mW. Its operating temperature ranges from -40° C to 125° C, making it suitable for engine compartments. 

The FBR53-LE can replace the company’s FBR53-HW 40A relay without altering its terminal arrangement. The single-pole FBR53-LE can switch heavy loads for fuel and EV applications including electric power steering, blower/fan motor, starter controller and infotainment systems. Reducing the power consumption of the coil compared to the FBR53-HW suppresses heat generation, which can reduce battery consumption in EVs and other vehicles with limited power.

The plastic-sealed type relay is RoHS compliant and uses a silver tin oxide contact material. A reflow-capable type is also available.
