Fixed inductors are components used in electrical circuits to conduct current. The 2256-21J inductor, in particular, is a dry wound tetric type that provides an operating temperature range of up to 175°C. This product is widely used in applications such as pulse transformers, bias supplies, and filter circuits.

2256-21J inductors are generally composed of a coil of an insulated wire, an iron core, a plastic enclosure and magnetic material. The horizontal enclosure of its design allows for increased heat dissipation for more efficient operating conditions. The core and the coil, which are the core components of an inductor, are sealed with a coating that provides excellent resistance to moisture and dust.

The working principle of a 2256-21J inductor is based on Faraday’s law of electromagnetic induction. The core of the inductor is used to store energy by creating a magnetic field when current passes through it. This magnetic field is then used to induce a voltage across an inductor\'s windings. This induced voltage is in opposition to the applied voltage, and so the current is then limited in an inductor.

To ensure optimal performance, 2256-21J inductors require a secure electrical connection. This can be achieved by using relatively long runs of wire or cable between the coil terminals and the circuit. This will reduce the potential for skin effect, thus reducing inductance, and improving high frequency responses. The core material of the inductor must be chosen carefully, as it affects the overall performance. The most commonly used materials are iron, ferrite, and powdered iron.

The 2256-21J is the most common fixed inductor in use today. Its low inductance makes it an ideal choice for pulse transformers, bias supplies, and filter circuits. With proper connection and core material selection, its performance can be maximized to ensure efficient operation. It is also capable of withstanding high operating temperatures, making it a viable solution for applications sensing temperatures up to 175°C.
