The TQ2SA-3V is a compact surface-mount relay featuring 2 Form C contacts designed for 3V DC nominal coil voltage operation. This relay offers a flat, low-profile design with dimensions of 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H), enabling space-efficient integration in modern electronic assemblies. The device demonstrates high sensitivity with nominal operating power of 140 mW for single-side stable operation, 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 TQ2SA-3V is ideal for telecommunications equipment, communications systems, and measurement applications where compact form factor and reliable switching performance are essential.
