Fixed inductors, otherwise known as chokes, store electrical energy in the form of a magnetic field in the space surrounding the windings of the inductor. The B78108T1222K000 is a type of fixed inductor, and it has many uses. This article will explain the application field and working principle of the B78108T1222K000.

The B78108T1222K000 is a fixed multi-layer inductor consisting of four windings. It has a rated inductance of 1.2 μH, a maximum current rating of 2.3A, and a maximum DC resistance of 0.0085 ohms. The package size of the B78108T1222K000 is 3.20 × 0.95 × 1.45 mm. It is typically used for applications related to current sensing, power supply, DC-DC converters, and on-board radio frequency (RF) circuits.

The working principle of the B78108T1222K000 is based on Faraday\'s Law, which states that a changing magnetic field creates an electromotive force (EMF) in a conductor. When a current passes through the inductor\'s windings, a magnetic field is generated. This magnetic field interacts with the coils, resulting in the generation of an opposing EMF. This EMF tends to oppose the current and limits it, thus getting the inductor to act as a choke.

The B78108T1222K000 is used in a variety of applications, including power flows, current sensing, and RF circuits. They are used for current sensing applications, because they can sense small changes in current and turn them into electrical signals. In power supply applications, the B78108T1222K000 can limit the ripple in the output voltage, as it reduces fluctuations in the current. It is also used in DC-DC converters as it helps regulate the transfer of power from the source to the load. Finally, in RF circuits, they are used to filter out radiation, reduce noise, and improve signal fidelity.

In conclusion, the B78108T1222K000 is a type of fixed multi-layer inductor, characterized by its four windings and a maximum DC resistance of 0.0085 ohms. Its application field includes current sensing, power supply, DC-DC converters, and on-board radio frequency (RF) circuits. Its working principle is based on Faraday\'s Law, with the magnetic field generated by the current passing through its windings resulting in an opposing EMF that opposes the current and limits it.
