Introduction to Fixed Inductors

Inductors, also known as coils, chokes, and reactors, are components of electric circuits that are essentially composed of a wire wound around a core, and are used to store energy or to pass signals. Inductors are used in every type of electrical circuit, from basics like AC/DC power supplies and power amplifiers to advanced micro-electrodynamics and consumer electronics products.In this article, we will discuss the specific characteristics and applications of a CDRH3D14/HPNP-3R2NC (CDRH) fixed inductor, as well as the working principle behind this base inductor model.

Overview of a CDRH3D14/HPNP-3R2NC Fixed Inductor

The CDRH3D14/HPNP-3R2NC is a base fixed inductor model, capable of providing a reliable, stable, and precise signal output with excellent frequency response. This inductor is designed to provide exceptional voltage and temperature characteristics, making it an excellent choice for many electrical applications.The CDRH model measures a full 14 mm in diameter with a 9.2 mm height, making it a medium-sized inductor that is suitable for most applications. The core material in the CDRH is a non-magnetic ferrite core, and the windings are composed of copper or aluminum foil, depending on the application and requirements. The inductance of this model is rated at 1.2 mH, making it an ideal choice for signal filtering and switching operations that require precise and fast delivery of signals. In addition, the CDRH model offers a wide range of maximum voltage ratings, starting from 1 to 10, which allows it to be used in a variety of applications. The operating temperature for the CDRH model ranges from -40 to +85 degrees Celsius.

Applications of the CDRH3D14/HPNP-3R2NC Fixed Inductor

The CDRH3D14/HPNP-3R2NC fixed inductor is suitable for a wide range of applications, ranging from general-purpose DC/DC converters to advanced digital filters, audio amplifiers, and power supplies. It is also well-suited for switching circuits, travel systems, and automated control systems. This base model is especially useful in audio amplifiers, where its precise inductance allows it to filter higher-frequency audio signals without introducing distortions or unwanted noise. Additionally, the wide range of maximum voltage ratings makes the CDRH suitable for applications with high-voltage requirements, such as power supplies, automotive solutions, and adjustable power converters.

Working Principle of the CDRH3D14/HPNP-3R2NC Fixed Inductor

The working principle behind the CDRH fixed inductor is fairly simple. When a flow of electrical current is applied to it, an electro-magnetic field is created, which causes the surrounding wire to coil around the core of the inductor. This creates a resistance which causes a voltage drop in the inductor. This resistance is also known as inductance, and it is this property that allows the fixed inductor to filter out higher-frequency signals, thus resulting in a more reliable and consistent signal.In addition, some models of CDRH fixed inductors come with a ferrite core material, which helps to reduce noise, interference, and power consumption. This ferrite core also has a higher permeability than other materials, which results in a higher inductance.

Conclusion

The CDRH3D14/HPNP-3R2NC fixed inductor is a medium-sized base model suitable for a wide range of applications, from basic power supplies to audio amplifiers and automated control systems. Its core material, copper or aluminum winding foils, and wide range of voltage ratings make it an ideal choice for many electrical applications. The working principle of the CDRH fixed inductor involves an electro-magnetic field created when an electric current is applied, resulting in the formation of a resistance, or inductance, that filters higher-frequency signals and produces a reliable signal output.
