The ARS10A12 is a miniature RF relay designed for high-frequency switching in telecommunications and broadcasting equipment. It features a 75O impedance, single-side stable contact configuration, and 12 VDC coil voltage, with surface-mount terminal in E layout for compact PCB integration. The relay operates up to 3 GHz with 10 W carrying power at 3 GHz, delivering excellent high-frequency characteristics including low insertion loss and high isolation across the frequency spectrum. Its miniature dimensions (14×8.6×7.2 mm) and Form C contact configuration make it ideal for antenna switching, tuner applications, and RF signal routing in mobile base stations, broadcasting equipment, and measurement instruments such as spectrum analyzers and oscilloscopes.
