180V Varistor Voltage Metal Oxide Varistor 05D181K Ce TUV Ios 9001 Certificate

Zinc oxide varistor

Color: Blue

Verification: CE

Product description

The varistor is a voltage limiting type protection device. Using the nonlinear characteristics of the varistor, when an overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby protecting the latter circuit.

Product specifications

Product advantages

1. Low standby power and no subsequent current

2. Suppress the stable performance of voltage characteristics

3. Low leakage current

4. A variety of lead forms: straight, curved and other special lead types

working principle

The varistor has its own sensitive voltage. When the voltage at both ends is equal to or exceeds its sensitive voltage, the resistance will decrease from infinity and rapidly decrease. It is similar to the short circuit and blows the circuit front fuse. The purpose of protecting the latter circuit is achieved. For a pulse with a small current and a high voltage, since it is equivalent to a short circuit, the high pulse is bypassed by him. When the high voltage is passed, his resistance value returns to infinity, thus protecting the latter circuit. Worn out by high voltage or high pulse

Use attention

1. When using the varistor, avoid direct sunlight and should not work in the open air or outdoors.

2. Do not use a solvent such as acetone to clean the varistor during use to avoid damaging the encapsulated epoxy resin.

3. Varistors may cause other problems due to the effect of the impedance of their capacitors on high frequency applications.

4. Direct exposure to the sun or the ambient temperature next to the heater may exceed the operating temperature that the varistor can withstand

Company profile

Thor has been designing new products to meet the RoHS directive since 2006. Thor’s ongoing commitment to RoHS compliance includes continuing efforts to reduce the presence of hazardous substances in the design and manufacture of a growing number of popular products. is committed to meeting the requirements of the European Union's Waste Electrical and Electronic Equipment (WEEE) directive. This prompt varies producers of electrical and electronic equipment to finance the take-back for re-use or recycling of their Products placed on the EU market after 2005.
