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.

Every audio power amplifier design starts with the same fundamental challenge: converting a low-voltage line-level signal into the high-current drive required by a reactive…
