WebJan 24, 2010 · If you're designing a choke-input filter, the choke must be the first filter element and must have a certain minimum value called the "critical" value. This value is … WebThe filter choke (schematic part 59, Philco part no. 32-7018) is open. Occasionally, I can get it to hold for a brief time and get a reading of about 2k ohms but over a short period of time it always measures open again. Any help in what values I need for a replacement or how to go about determining a replacement would be appreciated.

In electronics, a choke is an inductor used to block higher-frequency alternating currents (ACs) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped "bead" of ferrite material strung on a wire. The choke's impedance increases with frequency. Its … WebInductance is measured in Henries (H) and as a rule of thumb, a higher number equals more filtering.
