A varistor is an electronic component with a significant non-ohmic current-voltage characteristic. Topdiode VAR Series of transient voltage surge suppressors are radial leaded varistors (MOVs) designed for use in the protection of low and medium-voltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: 5mm, 7mm, 10mm, 14mm and 20mm, and feature a wide VDC voltage.

According to http://www.humblehomemadehifi.com/Cap.html ，WEET Shares Best Music Capacitor "Sound" in Hifi Collective and Audiophile Capacitors MusiCaps

WEE Technology Company Limited - WEE are Capacitors Specialist

WEET WMJ Coper Tupe Music Capacitors are warmly welcomed by raw speaker drivers (tweeters, woofers, subwoofer, midrange drivers, full range drivers), speaker kits, amplifiers, capacitors, resistors, and inductors. As for this WMJ type of capacitor, since audio is AC you will need to have a non-polarized capacitor. 

In our experience, WEET have never found anything better then a film PP capacitor for those audio applications. Please find below WMJ size table.MOQ for each value is 20pcs, free samples are here ready for you.

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.

WEET WPB 2000H at 105°C Super Low ESR Radial Polymer Aluminum Solid Electrolytic Capacitors Specifications

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.
