🌕This article is about the failure analysis of ceramic capacitors, which may fail in different environments. 1.Influence of humidity on deterioration of electrical parameters 🌝When the temperature in the lost [...]
1 Frequency Characteristics of Ceramic Capacitor 🍉1.1 Q value and frequency characteristics of ceramic capacitor The capacitance of the first type of ceramic dielectric capacitors (such as COG) is substantially [...]
Electrolytic capacitors aluminum foil corrosion process is widely used in industrial production.In actual industrial production, the tunnel corrosion process is generally used, including the steps of pre-stage chemical treatment → [...]
🔊In the production of aluminum electrolytic capacitors, increasing the capacitance value per unit volume is the direction of continuous improvement of capacitors. The capacitance is proportional to the effective area [...]
👇1. Q value and frequency characteristics of ceramic capacitor ⭐️The capacitance of the class Ⅰ of ceramic dielectric capacitors (such as COG) is substantially invariant with frequency over the entire [...]
🎇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 [...]
🪐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 [...]
🎈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 [...]
🌟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 [...]
🔊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 [...]
