FCL Components FTR-B3/FTR-B4/FTR-C1 signal relays are specialized for highly reliable automotive signal switching. They can operate at 1mA 400VDC and offer a guarantee of 1mA 500VDC switching (maximum switching power 0.4W). The lineup includes the small, low profile FTR-B3; the small, slim FTR-B4; and high insulation/wide gap FTR-C1 series.

The contact form is 2c (2 Form C), with a contact rating of 1A. 30VDC. The relays offer through hole/surface mount/space saving surface mount, with a non-latching or latching coil type.

They’re a great fit for switching audio circuits for emergency calls, battery controller applications including battery monitoring, abnormal detection of over-voltage and over-current, and low/high leakage detection.

FTR-B3/FTR-B4/FTR-C1 series relays are manufactured at a certified factory in compliance with IATF16949, an international standard for automotive management systems. They are UL and CSA recognized and RoHS compliant.
