Fixed Inductors – B78108S1225K000 Application Field and Working Principle

Fixed inductors, or inductors that are able to maintain constant inductance values independent of current, are commonly found in power-conversion circuits in various types of electrical applications. The B78108S1225K000 fixed inductor is one such device that can be used in a variety of applications. This article will cover the various applications and the working principle of this device.The B78108S1225K000 fixed inductor is a relatively small component with an outer diameter of 19mm and an inner diameter of 2.6mm. It has a breakdown voltage of 1.5V@100mA and is able to dissipate power up to 1.2W. This inductor is constructed out of ferrite with a magnetic core and two terminals, which makes it suitable for operation in higher temperatures.The main applications for the B78108S1225K000 fixed inductor include high-frequency switching applications, power supplies, and inverters. In high-frequency switching applications, this device is used to filter out high frequency noise signals, provide a path for current flow, and to help control the heat and energy generated by the circuit. In power supplies, this device is used for energy conversion and to help maintain a stable power output. Lastly, in inverters, this device is used to store energy and help maintain a constant voltage or current output.In terms of its working principle, the B78108S1225K000 fixed inductor works much like any other inductor. It acts as an energy storage element that stores energy in the form of a magnetic field when electric current is flowing through it. When the electric current is changed, either decreased or increased, the magnetic field collapses, releasing the stored energy. The amount of energy that is released depends largely on the inductance value, and for the B78108S1225K000, this value is 1225nH.The B78108S1225K000 fixed inductor is an excellent choice for use in high-frequency switching, power supply, and inverter applications. It is a durable component with a high breakdown voltage and is able to dissipate power efficiently due to its small size. Its working principle is relatively simple and works like most other inductors, storing energy in a magnetic field and releasing the energy when the electric current is changed. With this versatile device, designers can quickly and easily integrate it into a wide range of applications.
