Fixed inductors are electronic components used in applications which require inductance over a specified frequency range. The CDEP12D38NP-7R7MC-120 is a type of fixed inductor, and its application field and working principle are described below.

Application Field

CDEP12D38NP-7R7MC-120 is a low-profile surface-mount inductor, suitable for a wide variety of power line applications. It is suitable for powerline safety-critical application, such as critical medical equipment, as it meets UL94V-0 recognition. The CDEP12D38NP-7R7MC-120 is also suitable for board-level power-line conditioning, as it offers low DCR values. Finally, it is suitable for powering buck-boost power-line converters, which are used to increase/decrease the voltage of the power supply.

Working Principle

The CDEP12D38NP-7R7MC-120 is a fixed inductor, meaning that it has a constant inductance over a specified frequency range. This inductor works on the principle of electromagnetic induction, where a conductor is exposed to a changing magnetic field- in this case, the current passing through the wire. This induces a voltage across the conductor. The magnitude of this voltage is proportional to the flux change of the magnetic field- which is constant in fixed inductors.

The CDEP12D38NP-7R7MC-120 is wound with a high-quality enameled copper wire. This winding is encapsulated in a soft molded bobbin, to protect the wire from damage. The bobbin is then encapsulated in epoxy resin, ensuring a long product life. Finally, the inductor is coated with a humidity-resistant lacquer to protect it from corrosion.

In summary, the CDEP12D38NP-7R7MC-120 is a fixed inductor, suitable for use in a wide range of power line applications. It works on the principle of electromagnetic induction, and is wound with high quality copper wire. It is then encapsulated in a bobbin and epoxy resin, and coated in a humidity-resistant lacquer for protection.
