Zinc Oxide Varistors

5D471K Piezoresistor Zinc Oxide Varistor P5mm Varistor 05D471K is a kind of metal oxide semiconductor nonlinear resistance element mainly composed of zinc oxide. Resistors are sensitive to voltage and turn on quickly when the voltage reaches a certain value. Because the varistor has good non - linear characteristics, large flow, low residual pressure level, fast action and no continuous flow, etc. Widely used in electronic equipment lightning protection. Features: 1. Small

Metal Oxide Film 10D561K Piezoresistor Zinc Oxide Varistor Varistor 10D561K is a voltage limiting element sensitive to voltage changes, which is characterized by: at a specified temperature, when the voltage exceeds a critical value, its resistance value will sharply decrease, the current through it sharply increase, voltage and current do not show a linear relationship. Therefore, varistors are also called nonlinear rheostat. Features: 1. Small size, large flow capacity and
