Film Capacitors

A film capacitor is a type of capacitor that is constructed using a film as the dielectric medium. This type of capacitor offers a number of advantages over other capacitor types, such as a low losses and wider temperature range. As a result, film capacitors are commonly used in a wide range of applications across different industries, including automotive, power electronics, audio/video equipment and telecommunications.

B32642B6273J application field and working principle

The B32642B6273J is a type of film capacitor that is developed by the German manufacturer Epcos. This type of capacitor is mainly used in motor start and interference suppression applications that require higher frequency and higher operating temperature range. It is also used in power electronic applications such as frequency converters or inverters, or even in industrial or medical equipment.

The B32642B6273J capacitor is designed to have a low ESR (Equivalent Series Resistance), which is advantageous for applications that require a smooth DC voltage at the output. The capacitor is also designed to have low losses at higher frequencies, making it suitable for interrupting applications with high current loads. Furthermore, the B32642B6273J has a wide temperature range of -40 to +125°C and a voltage range of 250 to 1000V. This makes it a suitable candidate for applications that require high temperatures or high voltages.

The working principle of the B32642B6273J capacitor is fairly simple. When the voltage across the capacitor is constant, the current passes through the capacitor with no resistance. When there is an AC voltage applied, the capacitor will store the voltage, creating a dielectric field between its two plates. This dielectric field acts as an insulator and blocks the flow of current, storing the built up charge and allowing for a smooth flow of current through the capacitor.

The dielectric material used in the B32642B6273J capacitor is typically a plastic film. This type of material offers excellent dielectric properties and is highly resistant to temperature change. The plastic film also has a low dissipation factor and is highly resistant to moisture and other environmental conditions.

Overall, the B32642B6273J capacitor is a highly reliable product with excellent electrical properties and an excellent temperature range. It is suitable for a wide range of applications, including motor start and interference suppression, as well as power electronic applications such as frequency converters or inverters. Additionally, it has excellent dielectric properties, moisture resistance, and high temperature range. As a result, it is an excellent choice for applications that require electrical components that can withstand high temperatures and frequencies.
