Fixed inductors are electrical components that produce a circuit with an inductance value. They’re usually used in passive components such as low-pass filters, high-pass filters, and tuned circuits, and are also employed in DC-to-DC converters. B78108T1392K000 is a type of fixed inductor with a wide range of applications.

B78108T1392K000 Application Field

The B78108T1392K000 is a high-performance fixed inductor specifically designed for switching power supplies. It offers excellent surge current, high operating frequency, high current carrying, high temperature operation, and superior vibration resistance capabilities. It can be used everywhere in the power system, such as the primary side, secondary side, and control side.

It can also be used in various electronic circuits such as power amplifiers, computers, and digital communication equipment. With its high saturation current and a wide operating temperature range, the B78108T1392K000 can meet the needs of a variety of applications, including high-power DC/DC converters, power overflow protection, high-frequency low-noise circuis, and frequency discrimination. Thanks to its excellent frequency characteristics and high reliability, it is the ideal component for larger power systems.

B78108T1392K000 Working Principle

The B78108T1392K000 consists of a number of coils that store energy and can create an induced current, hence why it’s also known as an inductor. It works based on the principle of electromagnetic induction, which describes how a changing magnetic field can induce a current in an enclosed wire coil.

When the current flows through the inductor’s coil core, a magnetic field is formed around the inductor. This field then causes a voltage to be induced across the inductor due to the principle of Lenz’s Law. The voltage is proportional to the rate of change of the magnetic field, hence when the current changes, a voltage is generated.

The B78108T1392K000 is equipped with a ferrite core, which can increase the inductance value and ensure better regulation capability. As a result, the B78108T1392K000 can be an ideal choice for frequency discrimination, high-frequency low-noise circuits, and power overflow protection.

Conclusion

The B78108T1392K000 fixed inductor is a suitable component for different types of switch mode power supplies thanks to its excellent attributes. It offers excellent high-frequency characteristics, strong temperature and vibration resistance, and high saturation current. With its wide range of applications, it can be used in computers, digital communications equipment, and power amplifiers. Moreover, its operation is based on the principle of electromagnetic induction, where a changing magnetic field induces a current in a wire coil.
