What is a Fixed Inductor

A fixed inductor is an electrical component that stores energy in the form of a magnetic field when an electric current passes through it. It is used in a variety of applications including audio systems, power supplies, and circuit boards. Fixed inductors are made of metal coils that have a core and a winding of insulated wire. The core determines the inductance of the inductor while the windings form the magnetic field.

ER1641-473JM Fixed Inductor

The ER1641-473JM fixed inductor is designed for use in high frequency switching power supplies and other applications. It has an inductance of 0.47 mH with a tolerance of 28%. The operating temperature range of the ER1641-473JM is -55 degrees Celsius to +125 degrees Celsius. It has a high-frequency ferrite core material with terminals for connection.

ER1641-473JM Application Field

The ER1641-473JM fixed inductor can be used in high frequency switching power supplies, audio systems, circuit boards, and consumer electronics. In power supplies, the inductor helps convert direct current (DC) into alternating current (AC) at the desired voltage and frequency. In audio systems, the inductor helps filter out noise and provide a consistent signal. It can also be used in circuit boards to help stabilize the current and protect components from overcurrent.

ER1641-473JM Working Principle

When an electric current passes through the ER1641-473JM fixed inductor, the core of the inductor becomes magnetically charged, storing energy in the form of a magnetic field. This magnetic field has a resistance to changes in current, which helps regulate the current as it passes through. This helps protect components from overcurrent and helps stabilize the voltage and frequency of the current.
