Fixed inductors are electrical components that store energy in the form of an electromagnetical field. They are manufactured in a variety of styles and shapes such as screw terminal, radial lead, surface mount and through-hole for power electronics, automotive and custom applications. The SCRH74B-331 is a sophisticated fixed inductor with multiple features and applications.

Components and Technology

The model SCRH74B-331 is a small size radial lead inductor characterized by an inductance value of 330 μH ±30%, and a DC resistance of 0.6 ohms. It is encapsulated with an E-shaped polyurethane resin which makes it dust and moisture proof. The technology used in the manufacturing of the SCRH74B-331 is laser trimming, which ensures that the inductance values remain consistent regardless of the temperature changes. This reliable construction technique ensures that the inductor works consistently over a long period of time. Additionally, its wire wound core provides superior performance, making this model suitable for hard switching applications.

Working Principle

The working principle of a fixed inductor is quite simple. It consists of a circuit that is designed to store energy from the electrical current and the electromagnetical field. The voltage supplied to the inductor is alternating current (AC) and it changes from a positive peak to a negative peak. As the current passes through the inductor, energy is stored in the form of a magnetic field. When the voltage changes in the opposite direction, the energy stored in the magnetic field is released.

Applications

The SCRH74B-331 fixed inductor is widely used in the following applications:

• DC-DC converters
• Power supplies
• Motor speed controllers
• High power audio amplifiers
• LED lighting
• Communication equipment
