The TQ2SS-5V is a compact surface-mount relay featuring a 2 Form C contact arrangement with a nominal coil voltage of 5 V DC. It is housed in a flat, low-profile package measuring 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H), making it ideal for space-constrained applications. The relay exhibits high sensitivity with nominal operating power of 140 mW for the 2 Form C single side stable type, outstanding surge resistance rated at 2,500 V (2×10 µs contact and coil per Telcordia standards), and low thermal electromotive force of approximately 2 µV. The surface-mount terminal design with space-saving configuration enables efficient PCB integration and reliable performance in telephone-related equipment, communications systems, and measurement devices.
