The iron core inductors of inductance 50 H or more are suitable for low-frequency application. The inductors can also be classified based on the usage. The various sub-types of inductors based upon the usage are filter chokes or inductor, radio – frequency inductor or choke and an audio-frequency inductor or choke.

The AF (audio frequency) choke is used for blocking Audio frequency and only allowing DC. The RF (radio-frequency) chokes are designed to block RF frequency while allowing DC and audio frequency. Variable Inductor. As the name suggests, these inductors are designed to have variable inductance. This variable inductor is designed in more than one ...

inductors are inductors used in some DC to DC converters Chokes are divided into two categories: • Audio Frequency Chokes (AFC) – designed to block audio and power line frequencies (below 20 KHz) of AC while allowing DC to pass. These are “iron core” filter Chokes

In electronics, a choke is an inductor used to block higher-frequency while passing direct current (DC) and lower-frequencies of alternating current (AC) in an electrical 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 …

The reactance of the inductor is low at low frequencies and it basically shunts low frequency signals from the higher impedance speaker. One may think of the circuit as a voltage divider. Since X L = ωL and Z = √ (R 2 +X L 2), V in /V out = 0.31 at 100 Hz and 0.95 at 1000 Hz. The following figures show V out as a

form. Next to the bead is a shielded audio pot core inductor. It is surrounded by the ferrite ma-terial so that nearby 60hz magnetic fields do not couple into the windings and induce an audio frequency hum. The binocular core is somewhat like a bead core in that is allows for high induc-tance with few turns of wire.

One very satisfying aspect of 'rolling your own' audio frequency coils (aka chokes, aka inductors), is how well the simple inductance equations match measured end results. Unless you really manage to mangle the job, if you use the right equation and are reasonably careful to observe wire size, spacing (including insulation), and core diameter ...
