Description

FTR-B3GA4.5Z-B10 is a low-profile, ultra-miniature signal relay that fits dense telecom and instrumentation boards without sacrificing isolation or reliability. As a DPDT (2 Form C) bifurcated-contact design, FTR-B3GA4.5Z-B10 switches low-level signals cleanly while carrying up to 2 A per pole. Its 4.5 V standard coil requires only ~140 mW, enabling battery-powered and high-channel-count systems. FTR-B3GA4.5Z-B10 is plastic-sealed (washable), RoHS compliant, and qualified to telecom safety/EMI spacing—making it a solid drop-in for modems, line cards, measurement gear, and high-frequency signal routing.
