A separate specification lists the rated ripple current IAC, R at 100Hz at the upper temperature (+ 85 ℃, + 105 ℃ or + 125 ℃). The known core temperature (the core temperature can also be indirectly calculated by ripple current load, ambient temperature, wind speed and other parameters) and the service life under working voltage depend on the following service life formula: central temperature, rated life under rated voltage W.V., central temperature and inferred life under time voltage
When aluminum electrolytic capacitors are used, climatic conditions must be limited (partly for reliability and partly for temperature characteristics of electrical parameters). Therefore, it is important to follow the minimum / maximum temperature and humidity conditions stated in the IEC climate category. For the IEC category of each model, please refer to the corresponding specification. (1) The conductivity of electrolyte decreases with the decrease of temperature, which leads to the impedance of electrolyte
1. Aluminum electrolytic capacitor is of bipolar structure (see the mark on the capacitor body). Pay attention to the polarity during installation, and do not install it reversely. Application of alternating current or reverse voltage may cause short circuit or damage to the capacitor: the polarity in the AC circuit may be reversed or undetermined, so bipolar capacitors are not suitable for AC applications.
(1) Rated voltage VRThe rated voltage VR is the DC voltage that the capacitor is designed to withstand and is printed on the product body. For aluminum electrolytic capacitors, the rated currentThe voltage of 100 V is usually called "low voltage" capacitor, while the rated voltage > 100 V is called "…
What is the basic structure of aluminum electrolytic capacitor? Because the working principle of aluminum electrolytic capacitor depends partly on the electrochemical process, the product occupies a special position in various series of capacitors. Based on the advantages of high volume efficiency (…
