Introduction

Fixed inductors are inductors whose inductance is fixed, and they do not change significantly with variation in frequency or current. Fixed induction coils are widely used in many electronic circuits, such as high-frequency and RF circuits, and especially in power inductors for switching power supplies. The CDEIR8D38FNP-220NC is a specific type of fixed inductor which is commonly used in various applications.

What is CDEIR8D38FNP-220NC?

CDEIR8D38FNP-220NC is a general-purpose, 8-pin, surface-mount, shielded, low-profile, power inductor. It consists of a ferrite core and a coil enclosed in a plastic casing. It has a nominal inductance of 220nH.

Application field

The CDEIR8D38FNP-220NC is typically used in power management, battery supplies, converters and other switching applications. It is also used in audio systems, automobile electronics, LCD TVs and other electronic products. The main advantages of using the CDEIR8D38FNP-220NC are its low profile, wide operating temperature range, high current capabilities and low DC resistance.

Working principle

An inductor is a passive electrical component which by Faraday’s law creates a voltage proportional to the rate of change of current flowing through it. The CDEIR8D38FNP-220NC is an inductor which works on the same principle, however, its inductance is fixed; it does not change significantly with changes in frequency or current.When a voltage is applied to the CDEIR8D38FNP-220NC, current flows through it, and an electromagnetic field is generated. This field opposes the flow of electrical current, creating an additional electrical resistance which is known as "inductance". The inductance of the CDEIR8D38FNP-220NC is 220nH.

Conclusion

In conclusion, CDEIR8D38FNP-220NC is a fixed inductor which is typically used in power management, battery supplies, converters and other switching applications. It consists of a ferrite core and a coil enclosed in a plastic casing and it has a nominal inductance of 220nH. It has a wide operating temperature range, high current capabilities and low DC resistance. The working principle of the CDEIR8D38FNP-220NC is based on Faraday’s law, wherein it creates an additional electrical resistance proportional to the rate of change of current.
