The TX2SA-4.5V is a surface-mount relay featuring a 4.5V DC nominal coil voltage with 2 Form C contact arrangement and single-side stable operation. It delivers a nominal operating current of 31 mA with a coil resistance of 145 O, and provides a nominal switching capacity of 2A at 30V DC with standard Ag+Au clad contacts. The relay exhibits outstanding surge resistance (1,500V 10×160µs per FCC Part 68 and 2,500V 2×10µs per Telcordia), a 2,000V AC breakdown voltage between contact and coil, and a compact form factor of 15.0 × 7.4 × 8.2 mm. With a maximum operating speed of 10 cm and operate/release times of 4 ms maximum, this relay is well-suited for communications (xDSL, transmission), measurement, security, home appliances, audio/visual equipment, and medical device applications requiring high reliability and compact packaging.
