DBR70505SU is a UL-approved normally closed high voltage reed relay designed for applications requiring very high isolation voltages. It features rhodium contacts with 5kV isolation across contacts, a 5V DC coil with 38O resistance, and a must operate voltage of 3.7V DC. The relay offers low contact resistance of 50 mO maximum (15 mO typical), maximum switching power of 50W, and switching voltage up to 1000V DC/AC peak. 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.
