Fixed inductors have a range of applications across many different industries, with the 78F100J-RC model being one of the most popular. Its construction and design offer various advantages over other types of inductors, making it well-suited for a variety of tasks. It features a low resistance value, high inductance, and an inductance stability over a broad temperature range. It is an ideal choice for power supply and low-noise audio applications.

Application Field

The 78F100J-RC inductor is a suitable option for all types of DC to DC conversion applications. It is used in step-up/step-down DC to DC converters, DC-AC inverters, and boost converters. It is often used as a choke or filter in AC to DC power supply applications. When used as a DC filament inductor, it provides improved current stability to the filament, helping to reduce power fluctuations. Its low-inductance design makes it ideal for a variety of other power supply circuits as well.

In terms of audio applications, the 78F100J-RC inductor has excellent performance parameters and can be used as an output filter in audio amplifiers and speakers. It is also used in low-noise preamps and audio circuit boards, as the inductor helps reduce the voltage ripple and lower the signal-to-noise ratio. This makes the 78F100J-RC a suitable option for both hobbyists and professionals who require clean and precise audio reproduction.

Working Principle

The working principle of a fixed inductor is quite simple. When the current is applied through the inductor, a magnetic field is created. This magnetic field induces a proportional voltage across the component. This voltage is the means by which the inductor stores the energy of the current and then gradually releases it when the current is no longer present.

When the 78F100J-RC is used in power supply circuitry, it acts as a store and filter of energy. It prevents the power supply from fluctuating, instead delivering a consistent voltage or current output. In audio applications, the inductor helps to reduce the noise and distortion by smoothing out the voltage ripple. This helps to preserve the clarity of the signal and ensures crystal-clear sound reproduction.
