SMD Varistor 0402
The semiconductor ceramic electronic component zinc oxide varistor
is the main raw material for the manufacture of zinc oxide, the
resistance value changes depending on the applied voltage and the
non-linear change, since the resistance value of the voltage change
is very sensitive, said varistor or projections wave absorber.
