Non-Polarity MOV-07D Metal Oxide Varistor Wide Voltage Range
Generally From 18V To 1800V
The varistor is a voltage limiting protection device. Utilizing 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
realizing the protection of the subsequent circuit.
When the voltage applied to the varistor is lower than its
threshold, the current flowing through it is extremely small, which
is equivalent to a resistor with infinite resistance. That is, when
the voltage applied to it is below its threshold, it acts as an
off-state switch. When the voltage applied to the varistor exceeds
its threshold, the current flowing through it surges, which is
equivalent to a resistor with infinitesimal resistance. That is,
when the voltage applied to it is higher than its threshold, it
acts as a closed switch.
