DBR72405PU is a UL-approved normally closed high voltage reed relay designed for high reliability applications requiring very high isolation voltages. It features rhodium contacts with 5kV isolation across contacts, a 5V DC coil with 38O resistance, and panel mount configuration with wire wrap terminals. The relay offers low contact resistance of 50 mO maximum (15 mO typical), switching power up to 50W, and maximum switching voltage of 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 cardiac defibrillators, test equipment, and high voltage power supplies.
