Product Details
Zinc oxide varistors 7D561K for power circuits
Varistors 7D561K series are semiconductor voltage limiting surge
devices sintered from zinc oxide. They are widely used in
electronic circuits for their excellent nonlinear characteristics
and high surge absorption capacity. The products are mainly used
for surge protection on AC/DC power circuits and all kinds of low
frequency signals, control circuit boards and related lightning
protection modules. The varistor voltage can be from 18V to 1800V,
the same flow of the monomer can reach 70K[**] or even higher, the
diameter of the body has φ5φ7φ10φ14φ20φ25φ32φ40φ53 and 34*34 square
size.
