Fixed Inductors

Fixed inductors are widely used components in electrical and electronic circuits. Fixed inductors come in various shapes and performance specifications. The 0819R-24K series is one type of fixed inductors. It is specially designed for telecommunication applications, such as filter, amplifier, and modem circuits.

Application Field

The 0819R-24K is low-profile, surface-mountable inductor. It offers excellent high frequency characteristics, up to 5.5GHz equivalent series resonance frequency (ESR) and large current capacity up to 17A for saturation current @100KHz. It is a perfect choice for applications which require high efficiency and high power. These include, but are not limited to, power amplifiers for mobile phones, scanner antennas, ADC/DAC power supplies, base stations signal filter, RF switching, DC-DC converters, AC circuits, high frequency power line protection, and motor control circuits.

Working Principle

An inductor is a passive two-terminal electrical component that stores energy in a magnetic field. It consists of an inductor and a core. There are two types of inductors – air core and ferromagnetic core. The 0819R-24K inductor is built with a ferromagnetic core.

When a current passes through the inductor, the core helps to concentrate the magnetic fields in the inductor, thus amplifying the magnetic field produced by the passing current. This amplifying effect is enhanced when the inductor is operated at higher frequencies. The increase of the inductor’s current-induced magnetic field is proportional to the number of turns in the inductor.

Most of the inductors are designed to operate in the desired frequency range, and the inductance of an inductor is the most important parameter to consider. Inductors can be either air-core or ferromagnetic-core based. The 0819R-24K series inductors are ferromagnetic core based, which offer the highest inductance and frequency response for energy storing applications.

In summary, the 0819R-24K series is a type of fixed inductor that is suitable for high efficiency and high power-demanding applications. It features excellent high frequency characteristics and large current capacity.
