In order to defend the type is classified, stick piece pressure quick resistor has been belonged to pressure defend parts of an apparatus, press too defend basis of parts of an apparatus of effect way differ to be divided again for switch model press too defend parts of an apparatus and clamp bit-type are pressed too defend parts of an apparatus; Stick piece pressure quick resistor belongs to clamp bit-type to be pressed too defend parts of an apparatus. Stick piece pressure quick resistor applies in electric home appliances<gj and other electron product widely, overvoltage is protected since, prevent thunder, restrain surge electric current, absorb aiguille pulse, be restricted, high pressure destroys semiconductor of a confusion of voices of arc, disappear, protection yuan the action such as parts of an apparatus.

 

Stick piece pressure quick resistor is to press quick a kind of resistor, also be weighed for / piece type is pressed quick resistor. It is to use zinc oxide nonlinear the electric impact that resistor component serves as core and makes protects parts of an apparatus. Zinc oxide is nonlinear resistor component is with zinc oxide (ZnO) gives priority to body material, add a variety of other microelement, with the compound semiconductor component that craft of pottery and porcelain makes. Its main character is electric current what one voltage concerns is nonlinear. Should add in its voltage of two end under voltage of a certain a powerful person, namely “ is pressed quick when voltage ” , its resistance is great, become for; of million Europe class add in its voltage of two end to be pressed more than quick after voltage, resistance drops along with the heighten quickness of voltage, but small to ohmic class, fine long hair ohmic class.

 

 

Pressure quick resistor and common resistor are different, common resistor abides by Ohm’s law, and stick piece pressure quick the voltage of resistor and electric current are shown special nonlinear relation. Should stick piece pressure quick what two end add resistance when voltage is worth under nominal and rated voltage, its resistance approachs infinity, interior has flowed without electric current almost. Should stick piece pressure quick resistor two upright voltage summary prep above is nominal and rated when voltage, it will be guided connect by rapid puncture, turn into by tall block condition low block condition, working electric current increases quickly also. When its depress of two end report at nominal and rated voltage, stick piece pressure quick resistor can restore to be tall block condition again. Should press quick two upright voltage exceed resistor its are the biggest when restricting voltage, pressure quick resistor damages complete breakdown, can no more restore by oneself.

 

Stick piece pressure quick resistor because its volume is minor, apply more and more extensively at a few electron facility that hold equipment and miniaturization. Use at protecting component and circuit, prevent to be supplied in power source, control and the ESD that line produces. Stick piece pressure quick it is normal that capacitance value can divide the applied basis of resistor to mix for application of small electric capacity capacitance application:

 

1, application of product of small electric capacity, be like line of HDMI/DVI/USB high speed, IEEE 1394 port.

 

2, application of normal capacitance product, if be in advocate board the I/O port that go up (RS232, USB, PS2, VGA, frequency) with notebook computer, machine top box, MP3 player, DVD player, and butt joint system.

 

Stick piece pressure quick the main parameter of resistor has: Nominal pressure ratio of voltage of voltage, the electric pressure ratio, biggest control, incomplete, connect shed capacity, leakage current, voltage temperature coefficient, electric current temperature coefficient, voltage is nonlinear capacitance of coefficient, insulation resistance, static state.
