DBR71205SU 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 (DC or AC peak), a 12V DC coil with 240O resistance, and PCB mount with stud fixing and 1/4" spade HV connections. The relay offers low contact resistance of 50 mO max (15 mO typical), maximum switching power of 50W, switching voltage up to 1000V DC/AC peak, and switching current up to 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.
