Fixed Inductors

A fixed inductor, also known as a coil, choke, or reactor, is an electrical component used to store magnetic energy. It consists of a wire, usually of copper or other electrically conductive metal, wound around a core material, usually of a soft ferromagnetic material like iron, nickel, or cobalt. The core material is chosen to enable the inductor to hold large amounts of energy with minimal losses, and the wire is chosen for its electrical conductivity.

42103C application field and working principle

The 42103C is a popular fixed inductor, available in a variety of sizes and inductance values. It is commonly used in power supplies, audio applications, and other applications where electromagnetic energy must be controlled or stored. The 42103C holds a maximum voltage of 350 volts and a maximum current of 4.5 amperes.

The working principle of a fixed inductor is based on the behavior of electricity when passing through a coil. When a steady current flows through a coil, a steady magnetic field is generated around it. This magnetic field can hold an amount of energy determined by the current flow and the inductance of the coil. Thus, the coil acts as a capacitor, which can store energy, or be used to regulate current in a circuit.

In the case of the 42103C, the coil consists of two windings of 100 turns each, wound around a ferrite core. The inductance of the 42103C is dependent on the number of turns and the size of the core material. When the inductor is subjected to a current flow, a magnetic field is produced, which stores energy in proportion to the current and the inductance. As current through the coil is increased or decreased, the inductor can absorb and release energy in a predictable manner.

The 42103C is used in a variety of applications because of its ability to efficiently store and control electrical energy. It can be used to smooth out undesirable spikes or surges in current, filter out high-frequency noise, and even regulate the supply voltage in power supplies. The 42103C is a versatile and reliable component, capable of providing a variety of functions in electrical and electronic circuits.
