Fixed Inductors

Fixed inductors are passive two-terminal electronic components which store energy in the form of a magnetic field. The CF453215-3R9K can be classified as a type of fixed inductor.

CF453215-3R9K Application Field

The CF453215-3R9K is primarily used in switching power supplies, being able to withstand high ripple currents while providing superior performance. It is also used in the filtering of intermediate and high frequencies, further helping to filter out noise interference. It is typically found in consumer electronics, automotive, aerospace, industrial instrumentation and power converters.

CF453215-3R9K Working Principle

The operating principle of the CF453215-3R9K is based on the basic inductor structure, consisting of a conductive material, typically copper, and a magnetic core material. When an AC current is applied to the inductor, a magnetic field is generated which induces an opposite EMF. This EMF will oppose the source voltage, causing the current to decrease. The strength of the EMF, as well as the amount of current that can be induced, is a function of the inductance. The larger the inductance, the higher the induced EMF and the lower the current.

The CF453215-3R9K has an increased inductance, due to the presence of the ferrite core. This allows it to have an increased EMF, decreasing the current even further. It also exhibits high ESR which allows the inductor to have a much larger internal resistance and makes it more suitable for switching power supplies as it will better absorb the ripple currents.

The CF453215-3R9K also has a high self-resonant frequency which helps reduce the amount of noise and interference in the signal. By having a higher self-resonant frequency, it is able to filter out higher frequency signals more efficiently, resulting in a cleaner signal.

Conclusion

The CF453215-3R9K is a type of fixed inductor which is primarily used for switching power supplies and filtering high frequency noise interference. It has increased inductance, ESR and self-resonant frequency which make it a suitable choice for applications which require low current and clean signals.
