Teledyne Relays RF300 and RF303 Relays

Teledyne Relays RF300 and RF303 Series Relays are ultraminiature DPDT non-latching electromechanical relays designed to deliver consistent signal performance across broadband frequency ranges. These relays use a metal enclosure, welded construction, and hermetic sealing to maintain stability in varied conditions. Both relays offer repeatable RF behavior, low insertion loss, and high isolation, making them suitable for precision RF paths. The RF300 and RF303 relays differ in coil power and timing, with the RF303 using less coil power, and both operate from -55°C to +85°C with a dielectric strength of 350Vrms/60Hz at atmospheric pressure. These relays are used in RF paths requiring repeatability and controlled impedance, including attenuators and broadband signal networks.
