Fixed inductors are important passives for the implementation of electrical circuits. For radiofrequency applications, they are essential for impedance matching, filtering, decoupling, and for storing energy. B78108S1122K000 is a fixed inductor developed by EPCOS. Such inductors are used in a variety of applications, including low-noise analog circuits, power supplies, traction systems, and high-power RF applications, to name a few.

B78108S1122K000 features a thin, low-profile SMD construction with a large surface area for optimized inductance. It is fabricated with ceramic material and rated for a maximum operating temperature of 125°C. The inductance value is 11µH with a tolerance of ±10%, and it is able to tolerate a maximum direct current of 1.74A. A ferrite core material is used in this inductor, making it suitable for higher frequencies. The size of the inductor is 0.59×0.47×0.2 inches.

The working principle of this inductor is based on Faraday’s law of electromagnetic induction. When a current passes through a conductor, a magnetic field forms around it. When the magnetic field of a coil changes, an EMF is induced in the coil. Since the coil consists of numerous turns of the conductor, the induced EMF value is high, and the inductor can store electrical energy.

B78108S1122K000 is mainly used in analog circuits, particularly for high-frequency applications. It is used for differential signal lines in mixers, low-noise amplifiers, oscillators, active filters and linear circuits. It is also used for RF choke applications in switching power supplies. The small size and low profile of this inductor allows it to be used in a variety of applications that require a compact form factor. This inductor is also often used in timing circuits due to its high inductance and low DCR.
