👇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 [...]
🤚🏾 The electronic aluminum foil used in aluminum electrolytic capacitors, whether it is anode foil or cathode foil, requires the use of aluminum ingots to go through a complicated process [...]
🤚🏿In practical applications, the electrolytic capacitors can be classified in more detail according to the different metal materials and shapes of the anode valve of the electrolytic capacitor, the voltage [...]
🌟In the last article, we introduced that electrolytic capacitors have high specific capacitance, self-healing characteristics and high working electric field strength. 🌟Today, we continue to introduce the performance characteristics of [...]
Characteristics of paper dielectric film capacitors ⭐️Paper dielectric film capacitors are the earliest film capacitors. They are wound capacitors with capacitor paper as the medium and aluminum foil as the [...]
