Fixed inductors refer to those electronic components whose inductance remains unchanged with a certain frequency. They are widely used in electronic equipment to store energy. The 4445R-14J is a very popular type of fixed inductor in current market, with many features and advantages over other types. This article discusses its application field and working principle.

Application Field

The 4445R-14J is mostly used in electric circuit, such as motors, switch control, power supply, amplifiers, as well as other related products. It is designed to support high-frequency circuits and have a very low DC resistance, which helps reduce the power loss and improve the system efficiency. Moreover, it has high temperature stability and Q value, which ensures its long life in high temperature and reliability in electric circuit.

Working Principle

As a type of fixed inductor, the 4445R-14J works by mutual inductance, via the electromagnetic field generated by the electric current. Its working principle is based on Faraday’s law of induction, more specifically, Lenz’s law. When there is a voltage drop in the circuit, the electric field takes the direction of the voltage, so the current can flow in the circuit and induces a magnetic field.
The magnetic field created can then induce a voltage in the circuit, with the opposite direction of the original voltage drop. This process continues for as long as the circuit is powered, resulting in an inductor-like effect, with the electric current stored in the magnetic field. The stored energy in the magnetic field is provided to the circuit when the current flow is disrupted, which allows the electric current to circulate repeatedly.

Conclusion

The 4445R-14J is a popular type of fixed inductor, which has a wide application field and a simple working principle. It can reduce the power loss in electric circuits and improve the system efficiency, due to its low DC resistance and high temperature stability. This makes it a reliable and effective choice for many electric applications.
