Fixed inductors, also referred to as “paramagnetic cores,” are electrical components that have a fundamental purpose of increasing or decreasing the amount of electric current flowing along a conductor. The CDRH62BNP-270MC-B is a type of fixed inductor that is used in various applications, from RF interference suppression to ripple mitigation in switch-mode power supplies.

The CDRH62BNP-270MC-B consists of a ferrite core wound with a few layers of silver-plated copper wire. This particular inductor is designed to be “rugged”, offering insulation between its core and its leads for reliable performance in hostile environments. It also has a high saturation current rating and low-profile construction, making it an ideal choice for use in high-reliability industrial applications.

This inductor is available in a variety of footprints for easy integration into custom applications. It also has a very low DCR (direct current resistance) and a high creepage capability, meaning that it can handle higher power levels than conventional inductors. Its low DCR also eliminates the need for heat sinks, allowing it to be used in a wide range of applications.

The CDRH62BNP-270MC-B\'s primary application is as an RF interference suppression component, used in applications such as cellular base stations and other RF communications systems. Additionally, it can be used in switch-mode power supplies to reduce the high-frequency ripple of the input voltage. This is done by allowing a small amount of current to “creep” through the inductor, thereby smoothing out the input voltage.

The working principle of a fixed inductor is relatively simple. When a voltage is applied across the inductor, the core of the inductor stores energy in the form of a magnetic field. This magnetic field induces a voltage in the wire which is inversely proportional to the rate of change of the current passing through the inductor. Thus, when the current increases, the voltage induced across the inductor increases, resulting in an outward “push” on the current. This outward “push” of the current causes an opposition to the increase in current, which is referred to as inductive reactance.

In summary, the CDRH62BNP-270MC-B is a type of fixed inductor used in a variety of applications, from RF interference suppression to ripple mitigation in switch-mode power supplies. It has a high saturation current rating, a low DCR, and a high creepage capability, making it an ideal choice for use in high-reliability industrial applications. The working principle of a fixed inductor is based on the principle of inductive reactance, wherein the induced voltage opposes the increase in current.
