Fixed Inductors and CBC2012T220K Application Field and Working Principle

Fixed inductors or Choke coils are a type of electrical components, which are used to provide electrical functions and are made of materials such as steel, ferrite, etc. They are mainly used to store energy in a circuit and also act as a resistive element. They are used in electrical and electronic systems for a variety of applications, including filtering, tuning, energy storage, and other purposes.

The CBC2012T220K is a special type of fixed inductor that is specifically designed to supply a current in a specified range and reduce the impedance in the circuit. The inductor has a small size and is used in compact printed circuit boards and equipment without taking too much space. It has an operating temperature range of -55 to +125 degrees Celsius, making it an ideal choice for extreme environmental conditions.

The fixed inductor is made up of two parts bunched together – the inductor core and the wire windings. The core can be made up of any material, including iron, manganese, ferrite, and annealed iron powder. The material used determines the inductance and other performance aspects of the fixed inductor. The wire windings consist of enameled copper wire insulated by a glossy polymer film. It is these windings that provide the inductive characteristics of the inductor.

The CBC2012T220K has a rated current of 220mA and a rated inductance of 1.0 mH. It is able to supply a test current of 1.8A and works at a frequency range between 50 Hz to 10 kHz. Its DC resistance is 4.5 Ohm and the Q factor is 73. It is suitable for use in communications, audio, industrial control, and automotive audio applications.

The working principle of the fixed inductor is linked to the electromagnetic field that is produced when electrical current flows through the wire wound windings. This field creates a varying magnetic field that opposes any changes in current. This produces a slowing effect on the rate of flow of current, resulting in reduced impedance in the circuit. This allows the device to act as a filter and filter out any rapid changes in current, thus keeping the voltage steady in the circuit.

In summary, the CBC2012T220K is a special type of fixed inductor designed for specific applications. It is made up of two parts – the inductor core and the wire wound windings. It has a current rating of 220mA, and a rated inductance of 1.0 mH. Its operating temperature range is -55 to +125 degrees Celsius and it is ideal for use in communications, audio, industrial control, and automotive audio applications.
