The DBT72410-HR is a high-voltage reed relay from the D-HR series designed for applications requiring very high isolation voltages and low leakage current. This relay features 10 kV isolation across contacts with selectable rhodium or tungsten contact materials; rhodium contacts provide low contact resistance while tungsten contacts enable switching of higher voltages up to 5000 V DC or AC peak. The relay achieves a minimum insulation resistance of 1×106 O and operates over a temperature range of -20°C to +70°C, with coil voltage options of 5V, 12V, or 24V DC. It is ideal for sensitive test and measurement circuits, cardiac defibrillators, high-voltage power supplies, and other high-reliability applications where low leakage current losses and high isolation are critical.
