There are two classes of chokes. Power and audio frequency chokes have an iron core for greater inductance and filtering ability, while RF chokes use iron powder or ferrite beads and complex winding patterns that allow them to effectively operate at higher frequencies.

Boost inductors, fly-back inductors, and buck 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

This type of choke is also called "common mode choke", because it is used to filter common mode noise travelling over cables. Think of it as one turn of a wire around a transformer core. The magnetic flux induced by differential signals (on symmetric transmission lines) compensates each other, so that the signal is not influenced.
How do you calculate choke size in a power supply? | diyAudio

" How do you calculate choke size in a power supply?" It depends on where the choke is located. 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 calculated by: L (henries) = E (volts) / I (ma)

The LL1638 is a 2 coils choke for tube amplifier anode supply. The choke is available with different core air-gap, which results in different inductance and DC current capability. The coil is wound using our standard high internal isolation technique with isolation foil between each copper layer. The core is an audio C-core of our own production.
