Increasing demand for high-temperature film capacitors

Film capacitors have the self-healing capability, which is beneficial to any electrical system as it prevents the circuit from getting damaged and allows for the continuous operation. Many applications, such as drilling and mining, require machines that work at extremely high temperatures.

Many electronic devices, such as power correction systems and high-performance power conditioning equipment, are used in the avionics and aerospace sectors. These devices require capacitors that can work at elevated temperatures. Discrete capacitors, such as electrolytic capacitors and tantalum capacitors, can get damaged due to high temperatures.

Introduction of nanolayer film capacitors

In nanolayer film capacitors, the width of the film (dielectric) layer is some nanometers. Nanolayer cells have been introduced that can handle up to 150ºC. One of the most important features of a capacitor is the dielectric strength of the material. For improving the dielectric strength, it is necessary to improve the energy density of the dielectric.

An increase in the energy density is also necessary to reduce the overall size of the component. Also, film capacitors should be operable at higher temperatures. This makes them useful in industrial applications. A nanolayer dielectric can provide both these features. It has a high energy density, which is a required feature while developing next-generation capacitors.
