temperature sensor
Temperature Sensor

Temperature sensing is a different sensing resistor chip package inside the probe, commonly used temperature sensitive components are: thermocouple, platinum resistance, thermistor and so on. Temperature sensing customers in the design and styling, we need to select sensitive chip used, the probe dimensions and material, type and temperature of the wire. After the chip welding wire, After the probe is filled and encapsulated, a complete sensor device is formed, and the production process takes several hours. My products through: SJ 20722-1998, GJB 7396-2011, GJB 2433A-2011, ISO / TS16949: 2009 certification. ......Including: ntc temperature sensor, ptc temperature sensor, Pt100 temperature sensor, water temperature sensor, car sensor, ds18b20 sensor.


Thermistor
Thermistor
Thermistors are a class of sensitive components, divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to temperature coefficient. Typical characteristics of the thermistor are temperature sensitive and exhibit different resistance values at different temperatures. Our thermistors accord: JB / T9476-1999, JB / T 9474-1999 standard ...... include: ntc, ptc, SMD thermistors, thermistor power type, resettable fuse, Motor protection thermistor, etc.


varistor
Varistor
Varistors are resistor device having a nonlinear volt-ampere characteristics, mainly used for over-voltage clamping circuit when subjected to pressure, the excess current sink to protect sensitive devices. The main material is the metal oxide (MOV, Metal Oxide Varistor), which contains ceramic particles consisting of zinc oxide particles and a small amount of other metal oxides or polymer spacings. Varistor referred to as VDR, varistor called "surge absorber", sometimes referred to as "surge suppressor. Now widely used "zinc oxide" (ZnO) varistor, its main material has divalent elements zinc (Zn) and hexavalent elemental oxygen (O) formed.

resettable fuse
Resettable fuse
Resettable fuse is an over-current electronic protection components, can replace the ordinary current fuse. Traditional fuse over-current protection, can only be protected once, burned to be replaced, while the Resettable fuse with overcurrent / overheat protection, automatic recovery dual function. Polymer polymer PPTC and ceramic CPTC two kinds of Resettable fuse two, according to the package can be divided into two types, lead plug-in and SMD two. Can also be divided according to the voltage 600V, 250V, 130V, 120V, 72V, 60V, 30V, 24V, 16V, 6V and so on. .....
