Small Size 10D 431k Metal Oxide Varistor Fast Responding To
Transient Over-Voltage
The main characteristics of varistors are wide working voltage
range (6~3000V, divided into several files), fast response to
overvoltage pulse (nanosecond level), strong ability to withstand
impact current (100~2000A), and small leakage current (micro Ampere
level), small temperature coefficient of resistance, high
performance and low price, small size, it is an ideal protection
component, which can form overvoltage protection circuit, noise
elimination circuit, spark elimination circuit and absorption
circuit. When overvoltage pulses are superimposed on the power
supply network, after the varistor is connected, the peak waveform
of the overvoltage will be flattened and limited within a certain
range. When turning on or off the load circuit with inductive and
capacitive, the DC waveform appears switching spikes, and the
varistor can absorb this counter electric force in the circuit,
thus effectively protecting the switching circuit from damage.
Commonly used varistors include silicon carbide varistors and zinc
oxide varistors. Among them, zinc oxide varistors are more widely
used. It uses zinc oxide as the main raw material and adds a
variety of trace metal oxides. After mixed molding, A new type of
ideal overvoltage protection device assembled by sintering. Its
conductivity value changes nonlinearly with the change of applied
voltage. People call it a varistor or a surge absorber.
