Varistors are widely used in power circuits, communication equipment, household appliances, and industrial control systems, mainly for lightning protection and overvoltage protection.
Voltage Dependent Resistors (VDRs), also known as Varistors, are a special type of resistor
Varistors are made using ceramic technology, and their internal microstructure contains zinc oxide grains and grain boundaries. Due to the very neat arrangement of crystal molecules inside the grains, the electrical resistivity
Depending on the cross-sectional area of the current passing through, there are also situations where 0.1mA and 10mA are used to measure the varistor voltage. At present, chip varistors all use 1mA DC current input
As shown in the figure below, an NTC thermistor (Rv) is connected in series with a precision measuring resistor (Rm) to form a basic voltage divider circuit. The reference voltage VCC in this circuit
The polymer ESD suppressor (PESD) mainly applies the principle of nonlinear volt ampere characteristics of conductive polymer composite materials to provide ESD protection for electronic circuits. Its positive
If only considering the ESD characteristics of capacitors, it is necessary to ensure that the voltage across the capacitor does not exceed its breakdown voltage. However, in some specific circuit designs, composed of capacitors and resistors
The switch temperature, also known as the Curie temperature, is reached at which the resistance value shows a step increase, that is, when the resistance value reaches twice the minimum
