Patch pressure sensitive resistance application range chip type patch pressure sensitive resistance exterior structure and size
Publish:Shenzhen Tergy Technology Co., Ltd.  Time:2016-09-09

Patch based pressure sensitive resistance is a kind of voltage limiting protection device. The nonlinear properties of MLCV, when overvoltage appears in between the poles of MLCV, SMD varistors can voltage clamp to a relatively fixed voltage value, in order to achieve protection of circuit. The main parameters of the patch are: voltage, current capacity, junction capacitance, response time and so on.
Response time of MLCV for ns level, than the air discharge tube quickly, than the TVS tube slightly slow some, generally used for electronic circuit overvoltage protection of the response speed can meet the requirements. Junction capacitance of MLCV general in hundreds to thousands of PF magnitude, in many cases should not be applied directly in the high frequency signal line protection, application in AC circuit protection, because the junction capacitance than Congress to increase the leakage current, in the design of protection circuit need full consideration. MLCV flow capacity is larger, but the ratio of the gas discharge tube is small.

The biggest characteristic of MLCV is when added at a voltage above it below its threshold "UN", the current flowing through it minimal, equivalent to a shut the valve, when the voltage exceeds the UN and its resistance smaller, thus making the current flowing through it surge and little effect on other circuit changes so as to reduce the influence of peccadillo voltage on the subsequent sensitive circuit. By using this function, the abnormal overvoltage can be suppressed in the circuit, which can protect the circuit from excessive voltage.
Tergytech is specialize in the production of wholesale sensitive components, company production of plate type chip varistors are widely used in mobile phones, computers, MP3 and other electronic products, manufacturers are supporting the TCL, Konka, ZTE, Tianma micro, Tongzhou IT vendors. And to some large enterprises OEM oem. From the science and technology with its excellent product quality and strong R & D team, won the respect and trust of the same industry. Due to its small size, the patch patch is more and more widely used in many handheld devices and miniaturization of electronic devices.
