Fixed Inductors

Fixed inductors, sometimes referred to as coils, are electrical components that operate through magnetic induction in a circuit. They are generally classified into two categories: unshielded and shielded types. Fixed inductors can be used to store energy, damp oscillations, and terminate transmission lines. The specific part known as the B82422T1222J000 is a type of fixed inductor made by EPCOS that is well-suited for use in high frequency, small signal circuits, and power supplies.

Application Fields

The B82422T1222J000 is a general-purpose fixed inductor designed for use in a variety of electrical and electronic applications. It is perfect for high frequency, small signal circuits, and power supply filters. It can be used to build an adjustable inductor in a tank circuit for experimental purposes. This particular part is well suited for situations where switching speed and stability are of critical importance, such as in television circuits, adjustable filters, and switching power supplies.

Working Principle

An inductor operates through magnetic induction where a current is produced when a changing magnetic field is encountered. It consists of a conducting wire loop or coil and an iron core. When a current passes through the inductor, a magnetic field is created, which stores energy in the form of electrical current. As the current flowing through the coil changes, due to the inductance, the magnetic field will also change and generate an electrical voltage in the coil. This voltage is opposed to the source, and is generated by the changing magnetic field, which is generated by the changing current. This inductance effect is generated by the inductor’s coil and core configuration.

The B82422T1222J000 is a wire-wound fixed inductor constructed of a copper alloy core and a ropelike metallic winding formed around the core. It is a two-terminal component with a nominal inductance of 1222 nH, an SRF of 16 GHz, and a Q of 94. This inductor is designed for use in high frequency switching circuits and power supply circuits that require a high level of accuracy and stability. The bottom line is that the B82422T1222J000 is a great choice for any application that calls for an inductive component.
