WebFeb 2, 2024 · An RF choke (radio frequency choke) is a type of inductor, but it differs in its application, function, and design. An RF choke uses frequency selectivity to allow the passage of low-frequency DC signals while blocking high-frequency AC signals such as radio frequency. To do this, the RF choke has a high impedance over the range of frequencies ... Chokes are divided into two broad classes: • Audio frequency chokes (AFC) – designed to block audio and power line frequencies while allowing DC to pass • Radio frequency chokes (RFC) – designed to block radio frequencies while allowing audio and DC to pass. trevly menu
