Fixed inductors are electronic devices that store energy in a magnetic field, usually in the form of electric currents. These inductors can be found in a variety of electronic components and can be classified according to their design, material, output power, environmental conditions, etc. A recent addition to this family of inductors is the B82143A1222K, a permanently connected, self-supported wirewound fixed inductor. While this component has multiple uses, this article will discuss its application field and working principle.

The B82143A1222K is designed to induce currents in a single phase, two-wire AC circuit for various applications. It has an insulated base that houses four cores, two of which are connected by a winding while the remaining two are connected to the line. This arrangement makes the device well-suited for use in capacitor-start, capacitor-run, and split-phase induction motor circuits. In addition, the B82143A1222K can be used in isolating wiring in transformerless power supplies, as it provides a high-efficiency magnetic shield to reduce electric fields.

The working principle of the B82143A1222K involves the alternation of the current and voltage due to the application of a variable alternating current. This alternating current causes the inductor to produce a magentic field that induces a counter-EMF in the winding. This counter-EMF is proportional to the rate of change of current and is opposite in direction to the current. As a result, inductors act as a resistor to AC current. Since the B82143A1222K is self-supported, it does not rely on an external core and has a higher level of inductance.

In addition to the previously mentioned applications, the B82143A1222K can be used in other settings such as high-frequency applications, voltage regulation circuits, pulse transformers, and filter circuits. It can also be combined with other elements to form a complete circuit, which makes it a versatile and reliable component.

The B82143A1222K is a useful and versatile device due to its design and working principle. By inducing a counter-EMF in an alternating current, it functions as a resistor while the self-supported design provides a higher inductance. These features make it one of the most widely used inductors in a broad range of applications. Its use in capacitor-start, capacitor-run, and split-phase induction motor circuits, as well as in isolating wiring in transformerless power supplies, make it ideal for industrial and domestic use.
