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.

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
