WEET How to Understand the Meaning of the WEET Polymer Aluminum Solid Electrolytic Capacitor Marking
WEE Technology Company Limited - WEE are Capacitors Specialist
What are the parameters of WEET Polymer Aluminum Solid Electrolytic Capacitors? How to understand the meaning of the WEET Polymer Aluminum Solid Electrolytic Capacitors marking?
For example, the solid-Polymer capacitor shwoing as WPA470603, which represents the capacity of 470uF, and 6.3V represents the withstand voltage of 6.3V. This kind of electrolytic capacitance has positive and negative polarity. Generally, it will be marked with "-" (negative pole) on the package surface, or it can be distinguished by color band.
The structure of solid-state capacitor is basically the same as that of ordinary electrolytic capacitor(SMD Ecap), except that the original liquid part is replaced by the current solid part. In terms of installation form, it is no different from the original aluminum electrolytic capacitor, so customers do not need to change the circuit board structure, and directly replace it with solid capacitance according to the design needs. The stability of solid capacitor is much higher than that of common electrolytic capacitor.

WEE Technology solid aluminum electrolytic capacitor can work stably in high temperature environment, and the performance of main board can be improved directly by using solid aluminum electrolytic capacitor. At the same time, it is suitable for power filter because of its stable impedance in wide temperature range. It can effectively provide stable and abundant power supply, which is particularly important in overclocking.
Solid state capacitors can still work normally in high temperature environment, and maintain various electrical properties. The change of capacitance is less than 15% in the whole temperature range, which is obviously better than the liquid electrolytic capacitance. At the same time, the capacitance of solid-state electrolytic capacitor is basically independent of its working voltage, so as to ensure its stable operation in the voltage fluctuation environment.
The solid electrolyte will not evaporate, expand or even burn like the liquid electrolyte in the high temperature environment. Even if the temperature of the capacitor exceeds its tolerance limit, the solid electrolyte will only melt, so that the metal shell of the capacitor will not burst, so it is very safe.
The working temperature directly affects the life of the electrolytic capacitor. The life of WEET solid electrolytic capacitor and liquid electrolytic capacitor is significantly longer under different temperature environment.

The WEET WCA high-voltage ceramic chip capacitor is a round chip capacitor with ceramic material as the medium.The shell is ceramic for insulation.
One of the main characteristics of high-voltage ceramic capacitor is that it has high withstand voltage, and the voltage is generally greater than 1KV
The high-voltage ceramic capacitor has the voltage of 2KV, 3KV and 4KV, Often used in high-pressure situations, Up to 30KV
In the porcelain capacitor, the voltage below DC50V is generally called low voltage, DC100v ~ 500V is medium high voltage,
DC1000V ~ 6000V and is high voltage, and the voltage above DC6000V is ultra high voltage
Safety Y capacitor is also a high-voltage ceramic chip capacitor
The WEET WCA ceramic chip capacitor can be divided into class I porcelain, class II porcelain and class III porcelain. Class I porcelain, NPO, has good temperature, frequency and voltage characteristics. Because the dielectric constant is not high, the capacity is not large; class II porcelain, X7R comes next, has good temperature and voltage characteristics; class III porcelain has high dielectric constant, so the capacity can be large, but the temperature and voltage characteristics are not good, High voltage ceramic capacitor is generally small in size.
In addition, after breakdown, the ceramic capacitors tend to be in a short circuit state(this is its weakness) and after the film capacitor fails, it is generally in an open circuit state.The capacitance of high-voltage ceramic depends on the occasion of use, and the typical function can eliminate high-frequency interference.High voltage ceramic capacitors used in high power and high voltage fields are required to be small, high voltage withstand and good frequency characteristics.In recent years, with the progress of materials, electrodes and manufacturing technology, the development of high-voltage ceramic chip capacitor has made great progress and has been widely used. High voltage ceramic capacitor has become one of the indispensable components of high power and high voltage electronic products.
