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.
THB grade X2 film capacitor is adopted in the filter circuits of on-board chargers and battery management systems (BMS) for new energy vehicles.
The engine compartment is characterized by high temperature and humidity, coupled with extremely high safety requirements.
Free samples of the WEET WFC-A THB X2 series are available upon request. Please contact our sales team if you have any needs.

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.

MF 0.1% High Precision Metal Film Resistors are a widely used type of resistor. Literally speaking, they are metal resistors with leads at both ends. Have you ever carefully observed the color bands on them? What do they mean? How to identify the colors of 5-band metal film resistors?
Let WEET guide you to distinguish these colorful bands!
Introduction
First of all, the color band marking of 5-Band Metal Film Resistors contains three types of information: significant figures, multiplier, and tolerance. Different colors on the resistor represent different values. Next, I will list the corresponding values of each color one by one: Black = 0; Brown = 1; Red = 2; Orange = 3; Yellow = 4; Green = 5; Blue = 6; Purple = 7; Gray = 8; White = 9
1st band = First significant figure
2nd band = Second significant figure
3rd band = Third significant figure
4th band = Multiplier
5th band = Tolerance
Take the MF 5-Band Metal Film Resistors in the figure as an example, with color bands of red, black, black, black, brown:
Significant figures: Red = 2, Black = 0, Black = 0
Multiplier: Black = 10⁰ = 1
Tolerance: Brown = ±1%
Calculation result: 200 × 10⁰ = 200Ω (with a tolerance of ±1%)
After such an explanation from WEET, isn't it easy to identify the colors of 5-Band Metal Film Resistors?
