Fixed Inductors

Inductors are passive electrical components that store energy in an electromagnetic field. A fixed inductor is a type of inductor specifically designed to provide a certain amount of inductance.

4669-334K Application Field

The 4669-334K is a fixed inductor designed by Coilcraft. It is a power inductor that is widely used in high current applications, and is often used in telecom, automotive, and industrial applications.The 4669-334K has a wide range of features, including low DC resistance, high saturation current, and excellent temperature stability. The inductance range of the 4669-334K is 4.4µH to 10µH, with an operating temperature range of -40°C to +125°C. The 4669-334K also provides excellent performance when it comes to snubber and voltage regulator circuit applications, with a rated current of 10.5A and an inductance tolerance of ±20%.

4669-334K Working Principle

The working principle of an inductor is based on Faraday’s Law of Induction. According to this law, a changing magnetic field will induce an electric current in a closed circuit. When a current flows through a coil, a magnetic field is created and this field can be used to store energy. In the 4669-334K, the coil consists of a conductive wire wound around a form. The form has a magnetic core, which helps keep the magnetic field stable and resist saturation. The magnetic core of the 4669-334K is made up of a ferrite material. When an electrical current passes through the 4669-334K, a magnetic field is generated and this field induces a voltage across the inductor. The induced voltage is proportional to the rate of change of the current, in accordance with Faraday’s Law of Induction. The induced voltage also helps to resist changes in the current flow, which helps to stabilize the inductor’s electrical characteristics.

Conclusion

The 4669-334K is a fixed inductor designed for high current applications. It has a wide range of features, including low DC resistance, high saturation current, and excellent temperature stability. It works on the principle of Faraday’s Law of Induction, where a changing magnetic field induces an electric current in a closed circuit. The 4669-334K is a great option for power inductor applications, from snubber and voltage regulator circuits to telecom, automotive, and industrial applications.
