DBR71205U 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, a 12V DC coil with 240O resistance, and a must operate voltage of 9V DC. The relay offers low contact resistance of 50 mO max (15 mO typical), maximum switching power of 50W, and switching voltage up to 1000V DC or AC peak. 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.
