Introduction

Fixed inductors are widely used in electronic circuits for various applications. It helps in converting direct current (DC) to alternating current (AC) and also stabilizing AC voltage level. It can be categorized into two types, namely inductance and capacitance. Amongst these, inductors are made use of for storing electrical energy in the form of a magnetic field. Generally, they are used in filters to reduce noise, in impedance matching and in applications requiring large amounts of shielding. One of the most commonly used fixed inductors is the 2200HT-681-V. This inductor consists of an array of coils wound around a ferrite core in a specific way.

2200HT-681-V Application Field and Working Principle

The 2200HT-681-V is a surface mount, fixed inductor mainly used for audio and power applications as a noise filter for audio amplifier and pre-amplifier circuits. It can also be used to high-frequency switching applications and power supplies. The main purpose of the inductor is to provide AC coupling between the power and signal sources and thus reduce unwanted noise or interference. The working principle of 2200HT-681-V is based on Faraday\'s Law of Induction, which states that the inductance of a circuit is directly proportional to the number of turns of wire wound around it. In the 2200HT-681-V, the two layers of windings act as two inductors in series and they create an inductive field when a current is passed through them. This helps to reduce the peak voltage and stop AC ripples from reaching the output. The inductor also acts as a low-pass filter in the audio circuits, by suppressing high frequency signals and allowing the low-frequency signals to reach the amplifier.

Conclusion

The 2200HT-681-V is a fixed inductor which is widely used for audio and power applications due to its ability to reduce noise and interference and to filter out high-frequency signals. Its working principle is based on Faraday’s Law of Induction and it uses a double layer of windings to create an inductive field. This inductor enables the transfer of electrical energy by creating a magnetic field and thus helps in providing stable power supply and reducing noise levels in circuits.
