The reason why X2 safety capacitors are called safety class X2 capacitors is that they are used in situations where the failure of the capacitor will not cause electric shock or endanger personal safety. WEET WFC X2 Used for cross line and interference suppression circuits.
The X capacitor is connected across two lines of the power line, i.e. between "L-N". The X capacitor can suppress differential mode interference and is usually a metalized thin film capacitor with a capacitance of uF level. Most X capacitors are square in shape, similar to a box, and are usually marked with safety certification marks, withstand voltage words (usually AC300V or AC275V), and other information on their surface.

Select appropriate dipped varistors:
Different types of WEET Radial Leaded Metal Oxide Varistor have different protection voltage ranges. Select the type of varistor that can meet the circuit protection requirements based on specific application requirements.
Connect multiple varistors in series:
When the expected protection voltage exceeds the rated voltage of a single Radial Leaded metal oxide varistors (MOV), it is possible to consider connecting multiple varistors in series to increase the protection voltage. However, it should be noted that series connected varistors may increase the overall resistance value, affecting the normal operation of the circuit.
Parallel connection of other components:
In addition to using radial metal oxide varistors, they can also be connected in parallel with other components such as capacitors, voltage regulators, etc. to provide a more comprehensive protection circuit.
Control current limiter:
In circuits protected by radial leaded varistors, adding a current limiter can control the flow of current during overvoltage.
WEET shares some photos about 14D varistors Manufacturers Suppliers and 20D Series Metal Oxide Varistors MOV.
The resistance material of radial leaded metal oxide varistor is semiconductor, and the widely used "zinc oxide" (ZnO) varistors are composed of divalent element (Zn) and hexavalent element oxygen (O) as their main materials.
WEET will give you an example of a metal oxide varistor China dipped radial MOV, a lightning resistant varistor.
As the name suggests, the main function of lightning protection round zinc oxide varistor is to protect electrical appliances during thunderstorm weather.
The working principle of this type of WEET radial leaded zinc oxide varistor 6KV3KA is to be connected in parallel with the electrical appliance in the circuit. During normal operation of the electrical appliance, due to its high resistance, it basically does not work.
When a large current flows through the circuit, the lightning protection 10mm DIP Radial Varistors instantly conducts and causes all the current in the circuit to flow through the lightning protection varistor, thereby protecting the electrical appliances.
One issue that engineers need to pay attention to here is that although lightning protection radial leaded varistors can absorb a large amount of surge energy, they cannot withstand continuous currents above milliampere level.
Therefore, this must be taken into account when used for over voltage protection. In the usual selection process, the selection of lightning protection dipped varistors is usually based on two parameters: nominal radial metal oxide varistor voltage V1mA and current carrying capacity.

If choosing a low-quality varistor With Straight Leads or Kink Leads, there are several situations where it may fail:
The first type of degradation is manifested by an increase in leakage current and a significant decrease in the voltage sensitive voltage until it reaches zero.
The leakage current refers to the maximum direct current voltage applied at 25C or other specified temperatures
The second type of explosion, if the surge energy caused by overvoltage is too large and exceeds the maximum bearing capacity of the selected 6KV 3KA MOV Metal Oxide Varistor Surge Protection, the dipped varistor will experience ceramic explosion when suppressing overvoltage.
The third type of perforation, if the peak overvoltage is particularly high, the failure mode of the Radial Leaded Zinc Oxide Varistor 6KV3KA is mostly manifested as deterioration of each perforation (short circuit).
The solution is to connect a suitable circuit breaker or fuse in series with the dipped varistors when using it to avoid accidents caused by short circuits.
In summary, when a radial leaded varistor absorbs a surge and experiences a drop in breakdown voltage, its operating current will become too high until it burns out.
When a rupture occurs (such as cracking of the packaging layer and separation of the leads from the ceramic body), it will break the circuit and render the protection ineffective.
When this short circuit occurs, it will burn it out. When the usage environment or humidity of the epoxy varistor is too high, it will deteriorate (collapse voltage decreases), resulting in excessive working current until it burns out or short circuits.
When the operating voltage of the epoxy coated metal oxide varistors exceeds the rated working voltage, it will deteriorate (the breakdown voltage will decrease), resulting in excessive working current until it burns out or short circuits.
So, choosing high-quality products is very important, and we are exactly the partner you can trust completely.

A resistance device with nonlinear volt ampere characteristics, made of semiconductor materials, is called a High Power DIP Varistor.
The resistance material of WEET WVA Varistors is semiconductor, so it is a variety of semiconductor resistors.
The widely used "zinc oxide" (ZnO) varistors are composed of divalent element (Zn) and hexavalent element oxygen (O) as their main materials, hence they are also known as Metal Oxide Varistor China Dipped Radial MOV.
The over voltage protection of Radial Leaded Zinc Oxide Varistor 6KV3KA Varistors can be used in power protection, communication equipment, industrial control systems, and other fields. The lightning protection of
Round Zinc Oxide Varistor is mainly used for outdoor power systems and electrical equipment. The over current protection of DIP varistor 5D180K diameter 5mm can be used to protect power equipment, large electromagnets, and large motors from equipment damage caused by over current.
The role of WEET WVA Radial Leaded Metal Oxide Varistor in electronic products is mainly reflected in the following aspects:
1. Lightning protection:
MOV Zinc Oxide Varistor 5mm Disc Varistors can respond to and shunt lightning strikes or other overvoltages, protecting other components in the circuit from the effects of lightning strikes.
Varistors play different roles in different situations, but of course, in order for them to perform their intended function, it is necessary to use high-quality and high-performance Round Zinc Oxide varistors.
2. Over voltage protection:
The main function of a 6KV 3KA MOV Metal Oxide Varistor Surge Protection varistor is to clamp the voltage to a relatively fixed voltage value through its nonlinear volt ampere characteristics when the circuit is subjected to over voltage, thereby absorbing excess current to protect electronic components.
When the voltage in the circuit exceeds the threshold of the Varistor With Straight Leads or Kink Leads, its resistance value will sharply decrease, thereby converting the excessive voltage into a relatively small voltage to prevent damage to subsequent circuits or electronic components caused by over voltage.
3. Over current protection:
In some applications, High Power DIP Varistor can also be used for over current protection. When the current in the circuit exceeds the rated current of the Radial Leaded Zinc Oxide Varistor 6KV3KA, the resistance value rapidly decreases, diverting the additional current to ground and protecting other electronic components.
