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
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
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
P0(S0) and P2(S3) are refer to the class of safety protection. P0(S0) means non-explosion-proof. P2(S3) means explosion-proof.
Some customers wonder what is the best pin length for PCB capacitor. Let’s show you our suggestions as below. Let’s make the summary as below when making the bending pin operation for PCB board. If you choose devices and jig during the operation, we suggest 6mm pin length is the best. It will save some … Read more
