Fixed Inductors

The 1025R-92F is a type of fixed inductor, which is a passive two-terminal electrical component that stores energy in a magnetic field when electric current is flowing through it. It is made of a coil of insulated metallic wire wound around a core made of magnetic and non-magnetic materials, and typically comes in small sizes while its inductance can range from a few microHenries to several milliHenries.

Application Field

Fixed inductors can be found in various power supply circuits, including power factor correction circuits, half bridge supply circuits, full-bridge supply circuits, and more. Generally, they are used to provide a linear controlled current, or to limit the current in a given circuit. For the 1025R-92F, it is a heat-resistant surface-mount power inductor suitable for use in switch-mode power supplies, and can be safely used up to a maximum temperature of 350℃.

Working Principle

When a current flows through an inductor, it creates a magnetic field that, depending on the strength of the current, can vary in intensity. This magnetic field interacts with the electric circuit components and can induce a voltage, which in turn, causes other currents to be created. This phenomenon is known as inductance. With the 1025R-92F, this heat-resistant surface-mount power inductor can handle current fluctuation efficiently, thus making it suitable for various power supply circuits.
