How to Solve the Problem of Capacitor Temperature Rise

Capacitor temperature may rise too high due to long running time, improper capacitor selection, poor ventilation, medium aging, or increasing dielectric loss (Tan δ). Capacitor temperature rise will affect the life of the capacitor and eventually lead to capacitor damage. How to solve this problem? 1. The ambient temperature of the capacitor should be strictly … Read more

Aluminum Electrolytic Capacitor VS Film Capacitor

Capacitors, as one of the three basic passive electronic components in the world, occupy a significant position in the electronic components industry. Looking at the global capacitor market, ceramic capacitors and aluminum electrolytic capacitors have been occupied half of the capacitor market share. With the rapid development of power electronics technology in recent years, the application and market share of film … Read more

What is the principle of explosion-proof safety film capacitor?

The metallized electrodes adopt tiny fuses structure like picture 1. If there is any failure during capacitor operation, the power supply is automatically cut off by disconnecting the micro-fuse. In this way, the failure can be prevented and self-safety protection realized. Different Staus of the Segmented Films Pic. 2 Normal Status of safety Film Pic.3 The red point is accident … Read more
