| ZINC OXIDE VARISTOR | |||||||||
| 1) Are non-linner resistors utilize a semiconductor electronic ceramic element | |||||||||
| mainly composed of Zinc Oxide and its resistors change as a function of the | |||||||||
| applied voltage. It's called varistor or Transient surge absorbers. | |||||||||
| 2) Features | |||||||||
| Widely voltage 18v-1.8kv; | |||||||||
| Fast response to the rapidly increase voltage(≤25ns); | |||||||||
| Excellent non-linearity votage; | |||||||||
| Symmetric V-I characteristics; | |||||||||
| Great withstanding surge current(2000A/cm2); | |||||||||
| No follow-on current; | |||||||||
| Long life; | |||||||||
| 3)How to select a varistor(only reference) | |||||||||
| A:Varistor voltage | |||||||||
| Varsto voltage should be more than the operating voltage in over protective | |||||||||
| circuit, the formula is shown as the follow. | |||||||||
| V1mA=a.v/b.C | |||||||||
| a-power Voltage ripple coefficient usually 1.2; | |||||||||
| v-DC Voltage (significant value only AC power); | |||||||||
| b-Tolerance usually take 0.85 | |||||||||
| c-Ageing coefficient usually take 0.9 | |||||||||
| B:Withstanding surge current | |||||||||
| In general , withstanding surge current is max, Pulse current value which determined | |||||||||
| by test conditions such as wave-shape,amplitude and intermal time,when the amplitude | |||||||||
| decrease to 50% of the initial,it should be increased to 2 times of the initial in | |||||||||
| order keep the life longer,the surge current which is sbsorbed by the varistor should | |||||||||
| be less than max. withstanding surge current. | |||||||||
