Film capacitors were initially developed as a commercial replacement for the older paper capacitors, with their first prototype being created in 1924 by the Sprague Electric Company. These capacitors utilize a unique technique in the construction and production of a capacitor: the dielectric or electric insulating material is formed from a thin film, hence the name. Today, these capacitors are used in a wide variety of applications, from high-power transmission electronics to consumer electronics, and for their ability to withstand a wide range of temperatures and operating conditions.

The B25620B0567K703 capacitor falls under the subcategory of film capacitors. Its application field consists of medium to high-voltage and medium to high-power applications, commonly referred to as "medium current" applications. It is most often used as a precision part in power supplies, audio/video amplifiers, instrumentation, motor controls, and EMI/RFI filters. Not only does it have a high capacitance value of 470pF, but it also offers a high self-healing time of 750-900V for a single capacitor.

The working principle of the B25620B0567K703 capacitor relies on the property of the dielectric layer between the two conductive plates that makes it a capacitor. This dielectric layer is composed of three parts, the "first layer" which gives the capacitor its capacitance value, the "second layer" which contains the primary bulk of charge, and the "third layer" which acts as a buffer between the two other layers.

The main feature of the B25620B0567K703 is its ability to withstand a wide range of temperatures, while still providing high thermal resistance. This is made possible through the inclusion of an Aluminum oxide layer, which acts as a shield against high temperature and rapid thermal cycling. Furthermore, the B25620B0567K703 is designed with a high self-healing time and is able to withstand up to 900V and remain operational for a long time.

In summary, the B25620B0567K703 capacitor is an excellent solution for medium current applications, as it has a high capacitance value, high self-healing time, and excellent temperature resistance. It is particularly suited for power supplies, amplifiers, motor controls, and EMI/RFI filters, due to its distinct properties and long life expectancy.
