The TQ2SA-L2-5V-X is a 2-coil latching surface-mount relay designed for low-profile applications requiring compact switching control. It features a 5V DC nominal coil voltage with 2 Form C contact arrangement, providing dual independent switching circuits in a flat compact size of 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H). The relay incorporates outstanding surge resistance with FCC Part 68 compliance (1,500V 10×160 µs for open contacts) and Telcordia compliance (2,500V 2×10 µs for contact and coil), along with low thermal electromotive force of approximately 2 µV typical for surface-mount types. This relay is well-suited for telephone-related equipment, communications systems, and measurement applications where reliable latching operation and space-saving design are essential.
