🎇Low purity aluminum foil is used for the negative electrode. If the aluminum component does not reach the purity of 99.9%, based on cost considerations, it can still be used for cathode aluminum foil, because the purity of the cathode aluminum foil only needs to reach the level that it will not be corroded by the [...]
🪐1. Failure of normal use The failure of film capacitors can be the failure of normal use, and the probability of such failure is extremely low, and generally small batch applications may not be considered. Except for the very low probability of failure in normal use, the most common failures of film capacitors are caused by [...]
🎈The failure rate is an important parameter of the quality and reliability of electronic components. In addition to the manufacturing level, the failure rate has a lot to do with the application conditions. 💡The main factors that affect the capacitor failure rate during application are operating temperature and operating voltage. The relationship between the failure rate [...]
🌟Metal film capacitors have obvious advantages over metal foil electrode capacitors, that is, "self-healing." ✨“Self-healing”: The vacuum deposition metal attachment directly attached to the plastic film is only 20-50mm. If there are weaknesses, defects or the dielectric strength of the insulator in the mixture in the insulator is exceeded, the insulator will be broken down. The [...]
🔊The purity of electrolytic capacitor electrode aluminum foil listed in the standards of China, Japan, the United States and other countries is as follows. 🌟In addition to purity, high-purity aluminum foil with the same aluminum purity will also cause differences in capacitor performance due to different trace impurities. At the same time, it will also have [...]
