High frequency and RF (radio frequency) relays are high switch speed, high reliability and RF insulated relays designed for use in computers, testing equipment and radio broadcast systems. Additional features may include an internal diode, magnetic shielding and hermetic seals. These surface mount and through-hole relays are differentiated by operate and release time, coil current and contact rating. Contact forms include DPDT, SPDT and SPST configurations.

Learn how a diode conducts, how to identify anode and cathode, and when to choose rectifier, TVS, Zener or photodiode types for a circuit.
