The DAT71210F is a high voltage, high insulation resistance reed relay from the D-HR series designed for applications requiring low leakage current losses. It provides 10kV isolation across its normally open (SPNO) tungsten contacts and 17kV isolation between the contacts and the coil. Operating on a 12Vdc coil, this relay can switch a maximum of 7000V and 50W of power. Key features include a minimum insulation resistance of 1x10^14 Ohms, a maximum contact resistance of 250 mΩ, and a flying lead configuration for high voltage connections. Its high reliability makes it suitable for sensitive test equipment, cardiac defibrillators, and high voltage power supplies.
