Fixed inductors, as the name suggests, are electronic components that use a coil of wire wrapped around a core to inductively hold current in a circuit. The key feature of a fixed inductor is its ability to store energy in a magnetic field created by the inductor’s core. Fixed inductors are used in a wide range of applications, from amplifying low-level signals to providing necessary power levels in applications such as motor control, power supplies, and DC-DC power conversion.

The L0402R82BHLTR fixed inductor is a low-resistance surface-mount device designed for general-purpose applications. It has 112 nH of inductance and can handle currents up to 1.3 A. The L0402R82BHLTR is constructed from a high-temperature ceramic-steel material that offers superior thermal and electrical properties for reliable operation.

The primary application area of the L0402R82BHLTR fixed inductor is in switched power supplies. It is often used as part of the switching power supply feedback circuit, which monitors the output to regulate the power delivery. This feedback loop reduces power losses and helps maintain a constant voltage and current output level over a wide range of input voltages. It can also be used in electronic ballasts and motor control circuits.

The working principle of a fixed inductor is simple. When current passes through the inductor’s coil, the core material (usually ferrite) creates a magnetic field around it. The magnetic field then opposes any changes in the current flow, causing a back EMF (electromotive force) to be generated. This back EMF opposes the current flow, preventing it from exceeding a certain level. This is called inductive reactance and it’s what causes the inductor to act like a filter, blocking higher-frequency signals from passing.

The L0402R82BHLTR fixed inductor is an ideal choice for a variety of applications due to its low-resistance design and high current-handling capabilities. It can be used in applications requiring low-loss AC/DC power conversion, as well as in motor control circuits. Its compact size and excellent thermal properties make it suitable for use in high-density circuit boards.
