About this product
470v 10k471 Varistor is non-linear resistor utilize a semiconductor electronic ceramic element mainly compose of Zinc Oxide and its resistor change as a function of the apply voltage. It s called Varistor or Transient surge absorber.
What is a varistor?
A varistor is a voltage-dependent resistor (VDR). Its resistance is variable and depends on the voltage applied. Hence the word is compos of parts of the words “ var iable res istor ”. Their resistance decreases when the voltage increases.
In case of excessive voltage increases, their resistance drops dramatically. This behavior makes them suitable to protect circuits during voltage surges. Causes of a surge can include lightning strikes and electrostatic discharges. The most common type of VDR is the metal oxide varistor or MOV.
Varistors are nonlinear two-element semiconductors that drop in resistance as voltage increases. Voltage-dependent resistor are often use as surge suppressor for sensitive circuits.
Here are some examples of different packages that are often encounter. The block packages are use for higher power ratings.
Disc Block Radial leaded Axial leaded Characteristics of 10k471 Varistor :
A voltage-dependent resistor has a nonlinear varying resistance, dependent on the voltage applied. The impedance is high under nominal load conditions, but will sharply decrease to a low value when a voltage threshold, the breakdown voltage, is exceed. They are often use to protect circuits against excessive transient voltage.
When the circuit is exposed to a high voltage transient, the varistor starts to conduct and clamps the voltage to a safe level. The energy of the incoming surge is partially conduct and partially absorb, protecting the circuit.
The most common type is the MOV, or metal oxide…
