DBR70505TU is a UL approved normally closed high voltage reed relay designed for applications requiring high isolation voltages. It features rhodium contacts with 5kV isolation across contacts (DC or AC peak), a 5V DC coil with 38O resistance, and wire wrap (solder turret) HV connection terminals with stud fixing. 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 contact-to-coil isolation of 17kV, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
