Custom Self Healing Film Capacitors

Short Description:

Film capacitors are excellent capacitors due to their many excellent properties. Film capacitors are widely used in analog circuits. Especially in the part of signal connection, it is necessary to use capacitors with good frequency characteristics and extremely low dielectric loss, so as to ensure that the signal will not be too distorted during transmission.

FAQ
What does self-healing in film capacitors mean?
Self-healing characteristics of metallized film capacitors: When the metallized film capacitor breaks down due to the existence of a bottle point in the dielectric, an arc current will be generated immediately at the breakdown point, and this current density is concentrated at the middle point of the breakdown. Due to the thinness of the metal layer, the heat generated by this current is sufficient to melt and vaporize the metal near the breakdown point. A metal-free area is formed to restore the insulation between the capacitors, so that the capacitors can resume normal operation. The capacitance of the capacitor will decrease slightly after self-healing, but generally it will not affect the normal work.
