Typical shape

The Pressure Sensitive Resistor Can Not Be Used Casually, Choose The Pressure Sensitive Resistor To Pay Attention To The Model.We Need To Understand The Following Points When Using Piezoresistors

(1) No matter how the voltage changes, its large fluctuation value cannot exceed the voltage sensitive resistance's large allowable value, if the continuous working voltage exceeds the large allowable value, the voltage sensitive resistance will reduce the service time.

(2) When the varistor is connected between the power line and the earth, it may increase the voltage between the power line and the earth for some reasons, such as not having a good grounding. The varistor equipment we use must use a higher voltage than the voltage between the power line and the earth.

(3) The voltage sensitive resistor in the process of work to absorb the current as far as possible less than the flow of the product. The varistor MOV is mainly used for surge protection of low-voltage electrical appliances, most of which are zinc oxide varistors.It is a polycrystalline semiconductor ceramic component with zinc oxide as the main body, doped with a variety of metal oxides and made of typical electronic ceramic technology.The response time of the piezoresistor is ns, which is faster than the gas discharge tube and slightly slower than the TVS tube. In general, the response speed of the piezoresistor used for the over-voltage protection of the electronic circuit can meet the requirements.
