DBT72410F is a high-voltage reed relay from the D-HR series designed for applications requiring very high isolation voltages and low leakage current. The relay features 10 kV isolation between contacts with rhodium or tungsten contact materials, achieving a minimum insulation resistance of 1×10¹4 Ohms. It operates with coil voltages of 5V, 12V, or 24V DC, with a must-operate voltage of 3.7–9 V DC (depending on coil selection) and a must-release voltage of 0.5–1.25 V DC. The relay supports a maximum switching voltage of 1000 V DC (rhodium) or 5000 V DC (tungsten), with a maximum switching current of 3 A and a maximum carry current of 4 A, while maintaining a contact resistance of 28–150 O (rhodium) or 780 O (tungsten). With flying lead connections and high vacuum reed switch technology, this relay is ideal for sensitive test and measurement circuits, cardiac defibrillators, and high-voltage power supplies where low contact resistance and exceptional isolation are critical.
