TQ2SA-4.5V-Z is a low-profile surface-mount relay designed for automated assembly in compact electronic applications. It features a 2 Form C contact arrangement with a nominal coil voltage of 4.5 V DC, housed in a flat compact package measuring 14.0 mm (L) × 9.0 mm (W) × 5.0 mm (H). The relay is optimized for SMD automatic insertion with a height of 5.6 mm, meeting JIS C 0806 specifications, and includes tape and reel packing (500 pcs per reel) for high-volume production. It exhibits low thermal electromotive force of approximately 2 µV and is suitable for telephone-related equipment, communications, measurement equipment, and OA (office automation) applications where space constraints and reliability are critical.
