This component is also commonly used in power supplies, solar inverters and lighting systems.

The working principle of RCH654NP-390K is based on the principle of inductive reactance. As current passes through the component, a magnetic field is created, which in turn causes the voltage to be stabled. The magnetic field of the RCH654NP-390K has a linear relation with the amount of current, and the voltage remains constant over time and frequency. This is because the component is made of a ferrite material with a low hysteresis loop, which means that the magnetic field remains constant, even if the current changes.

In summary, RCH654NP-390K is a versatile fixed inductor based on a ferrite core with 390uH inductance value. Its special feature of a resin coating provides excellent dimensional stability and vibration resistance, and its wide application field includes automotive and industrial control, voltage regulators and lighting systems. This component works based on the principle of inductive reactance, with the magnetic field linearly proportional to the amount of current, providing an easy and stable solution for low-voltage power applications.
