The TQ2SA-9V is a compact surface-mount relay designed for telecommunications and industrial control applications. It features a flat, low-profile form factor measuring 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H), with 2 Form C contacts and a nominal coil voltage of 9V DC. 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 2,500V (2×10 µs contact and coil per Telcordia standards), and low thermal electromotive force of approximately 2 µV. The SA terminal type provides surface-mount compatibility with standard PCB assembly processes. This relay is ideal for telephone-related equipment, communications systems, and measurement applications where compact size and reliable switching performance are essential.
