CLQ4D10NP-221NC

Fixed Inductors

Fixed inductors are passive electronic components that store energy in the form of a magnetic field. They are used to filter or couple electric signals or to form a power supply for an electronic circuit.

The CLQ4D10NP-221NC is a fixed inductor that is designed to provide good impedance performance in high power DC/DC applications. The device includes an epoxy core, a winding material, and a coil form. It also has a scalable inductance rating that ranges from 1.2 to 390uH, and a high saturation current rating of 10A.

Application Field

The CLQ4D10NP-221NC is well suited for a wide variety of applications, including DC/DC converters, power supply filters, and audio circuits. It is also suitable for general-purpose switching-type DC/DC power supplies, such as those used in computers, communication equipment, and consumer electronics.

Working Principle

In a DC/DC converter for example, the CLQ4D10NP-221NC is used to increase the voltage of the input signal and to reduce its ripple noise. The fixed inductor is inserted between the input and output of the converter and acts as an impedance element to increase the current. This helps to reduce the output ripple voltage and to improve the overall performance of the converter.

In power supply filters, the inductor helps to reduce interference and noise, improving the stability of the power supply. It also helps to increase the efficiency of the power supply. In audio circuits, the device increases the signal-to-noise ratio, allowing lower frequencies to be heard more clearly.
