Introduction

Fixed inductors, also known as chokes, are electrical components that store energy in the form of electric current. They are used for power filtering and blocking, impedance matching, impedance adjustment, and signal quality optimization in various DC and AC circuits.

2256-08K Application Field and Working Principle

The 2256-08K Fixed Inductor is a component from a range of High Current Power Inductors specially designed for high current DC/DC converter applications. It is tape and reel packed, with an industry standard lead width of 2.46mm, which makes it suitable for automated placement.This 2256-08K Fixed Inductor features excellent temperature stability, high saturation current, high current capability, and low DC resistance. It is designed for input and output filtering of DC/DC power converter applications, high frequency switching power supplies and flyback power supplies. The 2256-08K Fixed Inductor also has a wide range of operating temperature from -40 to 125°C.The working principle of the 2256-08K Fixed Inductor is based on Faraday’s law of electromagnetic induction. When an alternating magnetic flux is linked with a coil, which consists of an inductor, the inductor will develop a voltage across its terminals that is proportional to the rate of change of the magnetic flux linkage. This developed voltage is stored in the coil itself and is referred to as an inductor voltage. This induced voltage, as well as the current flow in an inductor or choke, produces a magnetic field which is directly proportional to the current.

Conclusion

In conclusion, the 2256-08K Fixed Inductor is a component from a range of High Current Power Inductors specially designed for high current DC/DC converter applications. It features excellent temperature stability, high saturation current, high current capability, and low DC resistance. The working principle of the 2256-08K Fixed Inductor is based on Faraday’s law of electromagnetic induction, where an alternating magnetic flux is linked with a coil, producing an inductor voltage stored in the coil and magnetic field directly proportional to the current.
