SCB75C-151

Fixed Inductors

A fixed inductor is an electronic component with an inductance that remains largely unchanged over a defined range of operating temperature and frequency. Fixed inductors are commonly used in power supplies and frequency-dependent circuits such as filters, oscillators and resonances. Fixed inductors include common types such as rod-type coils, wire-wound inductors, variable inductors, and toroidal inductors.

SCB75C-151 Application Field and Working Principle

The SCB75C-151 is a particular type of fixed inductor designed for a wide variety of applications including power supplies, filters, audio amplifiers, and various other analog circuit designs. The design of the SCB75C-151 employs a ferrite-filled core which helps minimize the effects of current, temperature, and other external influences. This core provides an exceptional amount of stability in the inductor’s inductance value. It also has a small size allowing it to be used in tightly spaced or low-profile designs.

The SCB75C-151 has a high saturation current of up to 2,200 mA and a low DC resistance, allowing it to support higher current through the device with minimal losses. It also has a low self-resonant frequency of 150 kHz, which helps to minimize any noise interference caused by mechanical vibrations or other external disturbances. Additionally, the SCB75C-151 has a low temperature coefficient and relatively low temperature drift, making it suitable for designs that need to remain stable in a variety of temperature extreme environments.

The operating principle of the SCB75C-151 can be broken down into four steps. First, an electric current flow through the device, which in turn creates a magnetic flux. This flux interacts with the ferrite core, causing inductance to be generated. Next, the inductance value increases as the current through the inductor increases. Finally, when the current flow is removed, the inductance value will fall back to its original state. This cycle is repeated over and over again each time the current through the induction is altered.

In short, the SCB75C-151 is a particularly useful fixed inductor for a wide variety of applications due to its exceptional stability and performance in extreme temperature conditions. Additionally, its small size and high current saturation make it an ideal choice for modern, low-profile designs.
