The WEET THB grades for film capacitor is a safety-approved X2 capacitor designed to withstand a high temperature of 85℃ and high humidity of 85% RH. It must be used in accordance with the principles of circuit matching and safety regulations; otherwise, the following consequences may arise:
1. Incorrect Connection Position (Most Critical)
Connecting the THB grades for film capacitor improperly between the live wire and protective earth (PE) will pose risks of electric leakage and electric shock.
2. Mismatched Voltage Specifications
Using a capacitor with a voltage rating lower than the circuit’s operating voltage may easily cause a short circuit, blow the fuse, and in extreme cases, even lead to electrolyte leakage from the capacitor casing and ignition of the circuit board.
Selecting a capacitor with excessively high capacitance will increase circuit power consumption and shorten service life. On the contrary, insufficient capacitance will fail to suppress electromagnetic interference (EMI), resulting in frequent device crashes.
3. Improper Soldering
Excessively high soldering temperature will cause the sealant between the THB grades for film capacitor pins and the main body to crack, thus losing its Dual 85 high temperature and humidity resistance. Mounting the capacitor close to heat-generating components may cause thermal expansion and bulging of the capacitor.

We've all heard of X2 capacitors, but there's only one series that can withstand harsh environments - the WFC-A THB X2 series. It is a capacitor that passes the 85℃, 85% relative humidity (double 85) humidity and heat resistance test. Do you know where to use it?
INTRODUCTION
High-reliability home appliances
THB X2 series is used in the electronic control units of high-temperature and high-humidity home appliances such as dishwashers and disinfection cabinets.
Outdoor electrical equipment
It applies to outdoor LED street lamp power supplies and outdoor charging pile control modules.
These devices operate outdoors for long periods, exposed to high temperatures, high humidity, and heavy rain and snow, which accelerate the aging of ordinary capacitors.
Automotive electronics.

It is a component that integrates both a resistor and a capacitor, and is generally referred to as an X2 RC network.
So how can we judge X2 safety capacitor RC quality?
INTRODUCTION
The core method is to verify its capacitor section and built-in resistor section separately, combined with a visual inspection.
The commonly used tool is a digital multimeter.
Below are the detailed steps:
1. Visual Inspection
Check the appearance of the X2 Safety Capacitor RC for signs of cracking, deformation, or charring.
Examine whether the pins have issues such as severe oxidation, corrosion, or breakage.
Verify if the specification parameters on the surface are illegible.
2. Testing the X2 Safety Capacitor RC Built-in Resistor
The resistance value of the built-in resistor in an X2 RC snubber for AC power typically ranges from 1MΩ to 10MΩ.
Touch the two pins of the component with the probes of the digital multimeter respectively.
If the displayed resistance value matches the nominal value or the deviation is within ±10%, the resistor section is in normal condition.
3. Insulation Test
Touch the X2 Safety Capacitor RC two pins with the multimeter probes.
If the display shows OL, the insulation is good and there is no leakage.
If a numerical value is displayed and the buzzer sounds, the capacitor has leakage and is unfit for use.

What is the price of MKT Foil Capacitor 12uF? This is one of the top concerns for audio enthusiasts. However, the price of WEET WML Compact MKT capacitors is actually influenced by a variety of factors.
INTRODUCITON
Capacitor Specifications and Parameters: Capacitance and voltage rating are key influencing factors. Generally, the larger the capacitance, the more materials are required, and the higher the price. The same applies to the voltage rating. Additionally, it should be noted that the package size also affects the price.
Raw Material Costs: Price fluctuations of capacitor raw materials, such as metallized electrode materials and polyester films, directly impact the production cost.
Purchase Quantity: Typically, the larger the purchase quantity, the lower the unit price.
Policy and Environmental Factors: Government environmental policies may increase the production costs of enterprises. To comply with these regulations, enterprises need to invest more funds in environmental protection equipment and measures, and these costs are ultimately reflected in the product price.
SUMMARY
Based on the above analysis, the price of MKT capacitors is not fixed; It can be expensive at times and cheaper at others. However, WEET has consistently maintained a trend of high cost-effectiveness (can compete with Audyn MKT axial 12uF 160V Capacitors).
