Fixed inductors, also known as suspension inductors, are electronic components that use coils with a single winding to provide inductance for electric circuits. The CIL21J3R3KNE is an example of a fixed inductor, and this article will discuss its application field and working principle.

Application Fields

Fixed inductors are widely used in a wide range of electronic applications, and the CIL21J3R3KNE is no exception. It is most commonly used to add inductance to power supply filter circuits or reduce the switching time of switching power supplies. It can also be used in low-frequency radio frequency filters, and as filtering or blocking chokes to protect against noise interference.

In addition, the CIL21J3R3KNE is also used in the protection circuit of electronic products and the AC converter in the electronic instrumentation and control area. It is also found in a variety of automotive applications, such RF filters, DC-DC converters, and hybrid inverters.

Working Principle

The working principle of a fixed inductor is fairly straightforward. When an AC current is applied to the coil of the inductor, it creates an opposing magnetic field which causes an opposing EMF, or “back EMF”, to be induced in the coil. This “back EMF” opposes the applied current and tries to stop it from flowing, thus creating opposition, or “inductance”, to the current.

The amount of opposition, or inductance, that the fixed inductor provides depends on the number of turns in the coil, the size of the magnetic cores used, and the type of material used in the core. The CIL21J3R3KNE is a fixed inductor with three windings, and therefore has a relatively high inductance.

Conclusion

In conclusion, the CIL21J3R3KNE is a fixed inductor that is used in a variety of applications which require inductance. Its working principle is fairly straightforward and involves the use of a coil to create an opposing EMF which opposes the applied current and creates inductance. In addition, its three windings make it more inductive than other types of fixed inductors.
