Thanks to the excellent temperature and voltage characteristics, they can attenuate the effects of environmental shifts on audio signals, while their low ESR allows for higher current peaks without resulting in large voltage drops.

Working Principle

A B25834D1106K4 capacitor consists of several layers of metal film that are spaced apart and insulated by a thin dielectric material. The capacitor’s capacitance is determined by the interplay between the size of the plates, the distance between them, and the dielectric constant of the insulating material. In order to withstand high voltage and temperature shifts, the dielectric must possess high breakdown voltage and temperature coefficients, respectively. The electrodes, on the other hand, must be spaced apart in a certain pattern, thus ensuring the highest capacitance values and the deepest insulation gaps.

When voltage is applied across the electrodes, electric field lines are established between them and a charge is stored in between them. This charge acts as negative feedback, thereby decreasing the current flow between the electrodes, allowing for efficient energy storage and transfer. At the same time, as the electric field is established, the dielectric undergoes electrical polarization, further boosting its insulation properties and protecting the capacitor against overvoltage.

The use of B25834D1106K4 capacitors provides substantial performance benefits in a variety of applications, such as AC motors, power supplies, switching converters, and audio amplifiers. Their potential makes them an excellent choice for many applications, allowing for efficient energy storage, improved electrical properties, and excellent heat resistance.
