The TQ2SA-L2-5V is a 2-coil latching surface-mount relay designed for low-profile applications requiring reliable electromagnetic switching. It features a compact form factor of 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H) with 2 Form C contact arrangements and a nominal coil voltage of 5V DC. The relay exhibits high sensitivity with outstanding surge resistance, meeting FCC Part 68 specifications of 1,500V for 10×160 µs on open contacts and Telcordia standards of 2,500V for 2×10 µs on contact and coil. With low thermal electromotive force (approximately 2 µV for surface-mount types) and DIL terminal array compatibility, this relay is well-suited for telephone-related equipment, communications systems, and measurement applications where compact size and latching functionality are essential.
