The DBT71210FU is a high-insulation resistance, high-voltage reed relay from the D-HR series designed for applications requiring very high isolation voltages up to 15kV. It features tungsten contacts that enable switching of higher voltages while maintaining a maximum contact resistance of 250 mO and an insulation resistance of 1×10¹4 O minimum. The relay supports a maximum switching voltage of 10,000 V (DC or AC peak), maximum switching current of 2 A, and maximum switching power of 50 W, with a lifetime of 10? operations in dry switching conditions. The coil operates at 12 V DC with a must-operate voltage of 9 V and must-release voltage of 1.25 V, featuring an operate time of 3.0 ms and release time of 2.0 ms. This relay is ideal for sensitive test and measurement circuits, cardiac defibrillators, and high-voltage power supplies where low leakage current losses and high reliability are critical.
