Sensata Technologies Reed Relays SAR90503U

The SAR90503U is a UL-approved high voltage reed relay in the S(UL) series, designed for automated test equipment with a compact 30mm package. It features Rhodium contacts for low contact resistance, 3kV isolation between contacts, and 5kV isolation between contacts and coil, with a maximum switching voltage of 20V DC and current of 0.5A. The relay operates at 5V DC coil voltage, with an operate time of 1.0ms and release time of 0.5ms when a diode is fitted. Contact resistance is max 80mΩ (typical 30mΩ), and insulation resistance is min 10¹⁰Ω (typical 10¹³Ω). Operating temperature ranges from -20°C to +70°C, and the relay weighs 3.1g.
