DBR71205TU is a UL approved normally closed high voltage reed relay from the DB(UL) series, designed for applications requiring high isolation voltages. It features rhodium contacts with 5kV isolation across contacts, a 12V DC coil with 240O resistance, and PCB mount with stud fixing and wire wrap HV connection. The relay offers low contact resistance of 50 mO maximum (15 mO typical), maximum switching voltage of 1000V DC/AC peak, and maximum switching current of 3A. With an operating temperature range of -20°C to +70°C and 17kV contact-to-coil isolation, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
