The TQ2SS-5V-Z is a low-profile surface-mount relay featuring 2 Form C contacts and a 5V DC nominal coil voltage in single-side stable configuration. This relay is housed in a compact flat design measuring 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H), with space-saving surface-mount terminals (SS type) and tape-and-reel packaging (-Z designation) for automated assembly. The relay demonstrates high sensitivity with nominal operating power of 140 mW, 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. It is designed for use in telephone-related equipment, communications systems, and measurement applications where compact size and reliable switching performance are essential.
