In this article, we will discuss the application field and working principle of the CDRH8D43HPNP-2R7NC, a fixed inductor designed for high-frequency applications.

Applications and Specifications

The CDRH8D43HPNP-2R7NC is a high-performance, low-profile, surface-mount, fixed inductor with a tolerance of ±20% for frequencies up to 30 MHz. It has an inductance of 2.7 nH and supports frequencies up to 1 GHz. It is designed for a wide range of applications including RF power amplifiers, voltage regulators, voltage-controlled oscillators, antenna matching circuits, and frequency filters. It also has a broad temperature range, operating from -55°C to +125°C. In addition, it is RoHS compliant and offers excellent impedance and thermal characteristics.

Principle of Operation

The CDRH8D43HPNP-2R7NC is a type of fixed inductor, which is a passive two-terminal electrical component. It is made of two conductive plates or filaments wound together around a core material, such as ferrite or air. The basic principle of fixed inductor operation is based on Faraday’s law of electromagnetic induction, which states that when a wire is moved through a magnetic field, a current is induced in the wire. The induced current is proportional to the rate of change of magnetic flux through the coil. Fixed inductors are used to store energy as well as to produce a desired phase shift between two currents or voltages.

Uses

Fixed inductors are used in many applications due to their high power, high current handling capabilities and low losses. They are used in circuits such as broadcast and narrow band radio receivers, transmitters, and receivers for satellite communications, and in digital television systems. They are also used for RF power amplification, for antenna matching and frequency filtering, for impedance matching in voltage-controlled oscillators and voltage regulators, and for impedance matching in RF sources.

Conclusion

In conclusion, the CDRH8D43HPNP-2R7NC is a high-performance, low-profile, surface-mount, fixed inductor designed for a wide range of applications, from RF power amplifiers to antenna matching. It is based on the principle of Faraday’s law of electromagnetic induction and is used in applications such as broadcast and narrow band radio receivers, transmitters, and receivers for satellite communication, and in digital television systems.
