In electronics products such as vehicle, computer, and electric appliance, cutting-edge technologies are concentrated. New products are continuously produced to make our life convenient and comfortable.
Epoch-making improvement and development of electronic parts are necessary for creating new products. One of such electronic parts is the electrolytic capacitor (capacitor). Have you ever seen a small cylinder-shaped part on a board of home appliance?
 
The electrolytic capacitor has an important role; rectifying the flow of electricity and it is necessary for electronics products. In this electrolytic capacitor, the product of NKK, separator (insulating paper) plays an important role.
 
The role of separator is controlling the flow of electricity by separating positive and negative electrode in a capacitor. The thickness of the separator is only 15 to 130 micrometer. The thickness of a hair is approximately 80 micrometer, so you can imagine how thin it is.
 
In such ultra-small and ultra-thin environment, various performances such as durability for voltage, available electric capacity for storage, permeability, and instantaneous property are required for the separator according to the property of an electronics product.
