Fixed Inductors

Fixed inductors are inductive components, such as coils and chokes, which have a fixed inductance and are designed to be used in a specific application. They are used in a variety of consumer electronic products and the automotive industry, such as electronic ballasts, wireless charger modules, buck-boost converters, and high voltage power supplies. In these products, fixed inductors are used for a variety of purposes such as voltage regulation, filtering, damping, and power conversion. They are also used in various stages of antenna amplifiers and oscillators.

The B82476B1472M100 is a fixed inductor designed specifically for use in high-voltage circuits. It has an inductance of 14.72 mH and an operating temperature range of -55°C to +125°C.The inductor is manufactured using high-quality material for robust and reliable operation. It features a compact design with an interwinding capacitance of 30 pF and a maximum current rating of 22A.

Working Principle

Fixed inductors work on the principle of self-induction, which is the process by which a time-varying current induces an electromotive force (EMF) in its own circuit. When a current is applied to an inductor, it produces an associated magnetic field which, in turn, induces an opposing EMF across the inductor windings. This EMF opposes the rate of change of the applied current, resulting in an increase in the voltage drop across the inductor.

In addition, the inductor is designed to exhibit a stable inductance even when the applied current or voltage varies over time. This is because the opposing EMF is proportional to the rate of change of the applied current, and is therefore, constant when the current is varied gradually over time. The magnetic flux associated with the inductor affects its inductance, and therefore, the inductance of the B82476B1472M100 is fixed.

Application Field And Advantages

The B82476B1472M100 is mainly used in high-voltage circuits and power supply applications due to its high operating temperature range and high current rating. With a maximum current rating of 22A, it is capable of withstanding high current loads without the risk of damage.
