Introduction

Fixed inductors are electronic components that store energy in the form of a magnetic field. They are widely used in different types of circuits ranging from power to radio-frequency applications. The CDRH2D18/HPNP-1R7NC is one such type of fixed inductor from the LEM range of products. This inductor has a wide range of applications in both digital and analog circuit design. In this article, the application fields and working principles of this inductor will be discussed in detail.

Applications

The CDRH2D18/HPNP-1R7NC inductor is mainly used in a variety of power and RF circuits. One of the most common applications is in switch-mode power supplies (SMPSs) where it can be used as the primary or secondary inductor. This inductor also finds use in DC/DC converters, power filters, and voltage-controlled oscillators in both commercial and industrial applications. Additionally, it can also be used in high-end audio circuits for filtering and debouncing applications.

For RF applications, the CDRH2D18/HPNP-1R7NC inductor can be used as the primary inductor in base station amplifiers and FM radio broadcast systems. It is also commonly used in linear amplifiers, antenna couplers, and other high-frequency transmission circuits.

Working Principle

The basic working principle of a fixed inductor is based on Faraday’s Law of Induction. In this, an electric current passing through a coil of wire creates a magnetic field around it. When the current through the coil changes, this field induces a voltage in the opposite direction, which causes an opposing electric current to flow if there is an electrical load on the circuit.In the case of the CDRH2D18/HPNP-1R7NC inductor, a fixed coil is used to create a magnetic field and hence achieve inductance. The magnitude of the inductance depends on the number of turns in the coil and the material used for the coil structure. The inductor can store a fixed amount of energy and can convert between different AC frequencies.

Conclusion

In conclusion, the CDRH2D18/HPNP-1R7NC fixed inductor from the LEM range of products is a versatile component that finds use in a variety of power and RF applications. It stores energy in the form of a magnetic field using a fixed coil, exploiting Faraday’s law of induction. It is used in switch-mode power supplies, DC/DC converters, power filters, voltage-controlled oscillators, linear amplifiers, antenna couplers, and high-frequency transmission circuits.
