Foil inductive capacitors at high temperature and high pressure-control measures(III)

The control of the effect of heat seal on the breakdown of capacitor:

The heat size of the heat seal and the length of contact between the heat seal and the core should be adjusted to the benefit of the aluminum foil. In addition, the length of the outer film should be moderate, too long wave waste raw materials, too short hot seal easy to iron aluminum foil to make the two poles conductive breakdown.
