It operates on 5 V DC coil voltage with only 140 mW power consumption, making it highly sensitive. The relay provides 2A contact rating at 30 V DC, 1500 Vrms dielectric strength between contacts and coil, and 2500 V surge withstand capability (Telcordia). The sealed construction enables SMT reflow soldering compatibility, and the 5.6 mm profile height makes it suitable for space-constrained applications. The relay achieves 10^8 mechanical operations and 10^5 electrical operations at rated load.","working_principle":"The TQ2SA-5V is an electromagnetic relay that uses a 5V DC coil to generate a magnetic field that moves an armature, which in turn switches the DPDT contacts. When the coil is energized with the pick-up voltage (\u2264 3.75 V), the magnetic force overcomes the spring tension, moving the armature and transferring the common contacts from the normally-closed (NC) to the normally-open (NO) position. When the coil voltage drops below the drop-out voltage (\u2265 0.5 V), the spring returns the armature and contacts to the NC position. The sealed construction protects the internal mechanisms during reflow soldering. The AgNi contact material with Au cladding provides reliable switching for both power and low-level signal loads.","pin_description":"\n
