Chokes and Filters

We make Chokes and Filters

With many electronic parts becoming hard to  procure Cygnus developed a niche market to reproduce   filters and inductor with various sizes and inductance and Impedance. due to long lead-time or manufacturers stop producing the part. Cygnus Can design and produce the right Inductor,

What are inductors and chokes?  They are used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC). 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 low electrical resistance passes both AC and DC with little power loss, but its reactance limits the amount of AC passed.

The name comes from blocking—”choking”—high frequencies while passing low frequencies. It is a functional name; the name “choke” is used if an inductor is used for blocking or decoupling higher frequencies, but is simply called an “inductor” if used in electronic filters or tuned circuits. Inductors designed for use as chokes are usually distinguished by not having the low-loss construction (high Q factor) required in inductors used in tuned circuits and filtering applications.
