What are the differences between THB type X2 safety capacitors and regular X2 capacitors

For X2 safety capacitors, those who are not familiar with them believe that their function is to suppress power electromagnetic interference. In fact, X2 capacitors have many usage scenarios, some of which do not require high performance, but some require strict performance from X2 capacitors. Strong capacitor manufacturers, such as WEE Technology, will classify WFC-A X2 capacitors into anti-interference type, resistance capacitance voltage reduction type, THB high temperature resistance, high humidity type. What are the differences between THB X2 safety capacitors and ordinary X2 capacitors? What is THB type X2 safety capacitor?

Simply put, it means that WFC-A can pass the THB 1000h dual 85 test, also known as the dual 85 capacitor.

This test may seem simple, but for X2 safety capacitors, it is still difficult to pass because the two biggest factors affecting the lifespan of X2 capacitors are high temperature and humidity. Working in such an environment, ordinary X2 safety capacitors will quickly break down and have a short lifespan.
 Some electrical appliances are used in harsh environments, such as smart meters used outdoors, which may face high temperatures and humidity. In this case, THB type X2 safety capacitors must be used.

Characteristics and functions of THB type X2 safety capacitor:

Optimized series X2 certified type, using polymer polypropylene film medium, thickened metalized electrode, fully automatic spray welding process, 94V0 flame retardant PBT plastic shell, moisture resistant epoxy resin sealing, CP wire lead out. High voltage resistance, moisture and heat resistance, low capacitance drop, specifically designed for resistive capacitive voltage reduction circuits, such as LED driver modules, electric meters, small household appliances and other low-power electronic consumer products. The product can pass the THB1000h dual 85 test.

Compared to ordinary X2 capacitors, it has better high temperature resistance and high humidity performance, but the disadvantage is that the price will be slightly higher.
