The TQ2SL-5V is a compact surface-mount relay featuring 2 Form C contacts with a nominal coil voltage of 5 V DC, designed for high-reliability switching in telecommunications and industrial control applications. This relay measures 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H), providing a flat compact form factor suitable for space-constrained PCB layouts. It offers outstanding surge resistance with FCC Part 68 compliance (1,500 V 10×160 µs for open contacts) and Telcordia compliance (2,500 V 2×10 µs for contact and coil), along with low thermal electromotive force of approximately 2 µV for the surface-mount type. The relay features high connection reliability through its SL-type surface-mount terminal design and operates with nominal power consumption of 140 mW for the 2 Form C single-side stable configuration. Typical applications include telephone-related equipment, communications systems, and measurement devices where compact size, reliability, and low power operation are essential.
