FTR-B3 Ultra-Miniature Automotive Signal Relays

FCL Components FTR-B3 Ultra-Miniature Automotive Signal Relays are ultra-miniature, highly reliable signal relays crucial for modern automotive electronics. These low-profile (5.25mm height) automotive signal relays feature 1500VAC dielectric strength between coil and contact. The relays are electric vehicle (EV) ready, providing 1mA switching at 400VDC. The FTR-B3 offers energy-efficient non-latching (140mW) and latching (100mW) types. Applications include EV battery management systems (BMS) and emergency call systems.
