Film capacitors are electronic components that have been extensively used in many electronic products and circuits due to their superior performance and wide application. They can be found in various fields such as communication, medical, general industrial, consumer electronics, etc. One of the most popular types of film capacitors is B25856K4404J13.

Application Field: B25856K4404J13 is designed for DC applications such as general industrial equipment and lighting equipment. It features a metallized polyester film dielectric for long life and excellent performance. Other features include an operating temperature range of -25ºC~105ºC, withstand voltage of 500VAC 50/60Hz and a capacitance value of 4.4uF. This capacitor is also UL approved and RoHS compliant.

Working Principle: B25856K4404J13 is a type of capacitor that works as a charge storage element. In its simplest form, a capacitor consists of two conductive plates separated by an insulating film. When charged, either through a linear or nonlinear charge process, the capacitance of the capacitor is determined by the product of the dielectric constant of the film and the area of the plates. When an alternating voltage is applied to the capacitor, it will release its stored energy and the current will flow through the capacitor. Thus, B25856K4404J13 can store a certain amount of energy and efficiently discharge it.

In addition, B25856K4404J13 have a low equivalent series resistance (ESR) and excellent self-healing properties, which make them ideal for high-power applications. Furthermore, they have high insulation resistance, low thermal dissipation, and long-term stability, making them suitable for long-term use in many electronic circuits.

In summary, B25856K4404J13 are ideal for D3 applications that require a high energy storage capacity with low dissipation. The long-term stability, ESR, self-healing properties and excellent performance of these capacitors make them widely used in a variety of applications.
