The UD2-5SNU is a super-compact, single-coil latching signal relay from the UD2 series, designed for dense mounting applications. It operates with a nominal coil voltage of 5VDC, features a 2 Form C contact configuration made of silver alloy with a gold alloy overlay, and has a low nominal operating power of 100 mW. This relay provides a high surge capacity of 2500V between the coil and contacts, a maximum switching current of 1A, and an approximate operate time of 2 ms. Due to its small flat-package design and robust electrical characteristics, it is ideal for electronic switching systems, PBX, terminal equipment, and telephone systems.
