Fixed Inductors

Inductors are among the basic components in electronic circuits, with the function of storing energy through the phenomenon of self-induction. Fixed inductors, obviously, refers to the simplest form of inductor in which the inductance value is fixed and does not change with different time and voltage. Fixed inductors are widely used in different kinds of electronic circuits, due to their convenience and low cost.

One standard fixed inductor is the CIL21J1R5KNE. It is an axial wound round wire air core inductor suitable for use at frequencies up to 200kHz. This inductor is suitable for applications where low inductance values are required such as in DC/DC converters, voltage regulators, low loss radio frequency filters and Balun transformer, etc. The size of CIL21J1R5KNE is 17.5x11.5x14mm and it has a rated current of 1.1A.

The working principle of the CIL21J1R5KNE can be understood by looking at the inductor’s types. CIL21J1R5KNE is an air core inductor, which means there is no magnetic core inside it. Instead, it uses an air core and the core is enclosed by an axial wound and round wire coil. This type of inductor exhibits two fundamental characteristics: inductance and impedance. The inductance of CIL21J1R5KNE is determined by the number of turns in the coil, the size of the core, the current in the coil, and the material of the inductor. The impedance of the CIL21J1R5KNE is determined by the inductance and tends to be higher at higher frequencies. The working principle of the CIL21J1R5KNE is based on the phenomenon of electromagnetic induction. When a current through the CIL21J1R5KNE, it induces an electromotive force in the coil, which generates a magnetic field. This magnetic field creates a force that opposed the motion of the inductor and thus the inductor\'s impedance is increased.

CIL21J1R5KNE fixed inductors are widely used in various electronic systems, especially in power converters, voltage regulators, low loss radio frequency filters and Balun transformer, etc. They provide stable inductance and low impedance at higher frequencies. Understanding the working principle of CIL21J1R5KNE make it easier to choose the right one for a specific application.
