SPDT High Repeatability TO-5 RF Relay
5, 12, and 26.5 volt coils

The RF311 and the sensitive RF331 are single-pole, dual-throw (SPDT) relays that deliver improved repeatability and performance over DC to 8 GHz with less than 1.0dB insertion loss.

They are available in coil voltages of 5, 12 and 26.5 Vdc. The RF311 is designed for use in attenuator and other RF circuits. Features include high resistance to electrostatic discharge (ESD), a metal enclosure for EMI shielding, ground pin option to improve case grounding and high isolation between control and signal paths. The relay is RoHS compliant. The RF331 has twice the coil resistance of its companion relay, the RF311, thus requires half the power to operate. The RF311 has a profile 0.1" shorter than the RF331.
