DAT70505F-HR is a high-insulation resistance reed relay designed for high-voltage switching applications requiring 5kV isolation between contacts. The relay features rhodium contact material, which provides low contact resistance and excellent reliability for sensitive test and measurement circuits. It is configured as a normally open (SPNO) contact form with a 5V DC coil voltage and flying lead connections for PCB mounting with high-voltage isolation. The relay operates with a maximum switching power of 50W, maximum switching voltage of 1000V DC or AC peak, and maximum switching current of 3A DC or AC peak. With an insulation resistance of 1×106 O minimum and capacitance across contacts of less than 0.2 pF, this relay is ideal for cardiac defibrillators, test equipment, and high-voltage power supplies where low leakage current and high isolation are critical.
