Product Description
Features
1. Advantages
(1) Minimal capacity decay over extended usage;
(2) Easier metal spraying thanks to the thick coating compared with aluminum films;
(3) Low resistivity due to zinc oxide during metal spraying.
2. Disadvantages
Poor resistance to atmospheric corrosion, limiting long-term storage capabilities.
Applications: Capacitors of power, refrigerator, air conditioners, and other devices
Structure
1. Non-thickened aluminum-zinc film edges
2. Thickened aluminum-zinc film edges
