Film capacitors, popularly known as "plastic film capacitors", are almost all made of polyester, polypropylene film or impregnated paper as the dielectric substrate, while B25620B158K882 is one of capacitors in this category. As we know, film capacitors are widely used in everyday electronics, and the B25620B158K882 is no exception.

B25620B158K882’s application field, as an excellent film capacitor, makes it rather diverse. It performs well in power supply circuit, and is the perfect choice for use in the output stage of power supplies, linear applications and resonant circuit for converting rectangular to sinusoidal currents. Additionally, it can be used in the circuits of power factor improvement, energy saving, and as a filter element for functional circuits, such as audio circuits. Besides of that, it is also concluded in applications in audio crossover networks and phase splitting circuits, which is perfect for a wide range of consumer electronics from personal audio to automotive.

Additionally, with its working principle, B25620B158K882, a long life capacitor, is designed to last for many years. This capacitor works based on the principle of dielectric absorbtion. The working principle is in the following way: when a voltage is applied across the capacitor, the conductor on the surface of the electrode-dielectric system attracts and absorbs a small proportion of it. As a result, a non-polar layer composed of electrons, dipoles and dipoles becomes the conductive layer between the electrodes, and the resistor is formed.

As a result, the capacitor’s leakage current is very small. The dielectric absorption characteristics indicate that B25620B158K882 can easily provide the needed electrical energy for many applications. This electro-active layer quickly forms a discharge path after the electric charge. So the progressive absorption of electrons produces the “dielectric absorption voltage”.

Besides, the B25620B158K882 is able to operate in frequency range up to 100 kHz with the extra high insulation resistance and very low dissipation factor. To conclude, B25620B158K882 is a versatile film capacitor which offers stability, high insulation resistance, low DC leakage current and longer life compared to other capacitors.
