Fixed Inductors

A fixed inductor, also known as an inductor or choke, is a passive two-terminal electronic component that stores electrical energy in the form of an electric current in a wire wound as a coil around a core. It is used in electronic circuits to increase the efficiency of power supplies, reduce interference, limit the electrical current in the circuit, and control the voltage levels in the power supply. Fixed inductors are widely used in high-frequency applications such as radio and television transmitters, receivers, amplifiers, digital communications, and other electronic systems.

The B82476A1154M000 is a fixed inductor produced by TDK-EPC corporation.

The rated current of the B82476A1154M000 can be increased 1.3A with a temperature rise of 40°C.

The basic working principle of the fixed inductor is to create a closed, or "short-circuit", loop to increase the electrical current in the circuit. This creates an interference which affects the electrical current entering the circuit, allowing the power supply to work more efficiently and limiting the current to the desired levels. Additionally, the inductor produces a magnetic field in the core that increases the efficiency of the power supply. It also limits the voltage levels in the power supply by changing the impedance of the circuit.

The B82476A1154M000 fixed inductor is widely used in power supply circuits for audio amplifiers, receivers, and other electronic devices.
