The second is the impact life, that is, can reliably withstand the prescribed impact of the number of times. After the pressure-sensitive resistor intervention system, in addition to the "safety valve" protection, but also bring some additional effects, this is called "two times effect", it should not reduce the system's normal operating performance. At this time to consider the main factors are three, one is the pressure-sensitive resistance of the electrical capacity (dozens of to tens of thousands of PF), the second is in the system voltage leakage current, the third is the Varistor nonlinear current through the coupling of the source impedance of other circuits.
