Thermistor Characteristics
In Ya Xun, thermistor is the most important feature of long life, high precision. After the ultra-high temperature, high pressure test. The product is still high precision, high sensitivity, high reliability, it can still work for a long time stable.
1. Thermistor typical characteristics are sensitive to temperature, different temperatures show different resistance values.
2. (PTCR) The higher the temperature, the greater the resistance value. Negative Temperature Coefficient Thermistors (NTC) have the lower resistance at higher temperatures, and they belong to the same semiconductor device.
3. PPTC thermistor (polymer positive temperature coefficient) is made of polymer material filled with carbon black particles. This material has a certain conductivity, and thus can pass the rated current.
4. High sensitivity, the resistance temperature coefficient than the metal 10 to 100 times higher, can detect the temperature change of 10-6 ℃;
5. After making the temperature sensor, the working temperature range is wide, room temperature device for -55 ℃ ~ 315 ℃, high temperature device temperature is higher than 315 ℃ (currently up to 2000 ℃), low temperature devices for -273 ℃ ~ -55 ℃;
6. Small size, it is possible to measure other thermometer can not measure the gap, and the temperature of the body cavity of a biological vessel;
7. Easy to use, the resistance value can be arbitrarily selected between 0.1 ~ 100kΩ;
8. Easy to process into a complex shape, can be mass production;
9. Good stability, strong overload capacity.
Application Classification of Thermistors
At present Ya Xun to provide semiconductor, metal and alloy three kinds of materials, thermistor manufacturing, the function of each material, features have their own uniqueyou. Taking into the account the cost factors, our engineers are happy to propose the most suitable material recommendations based on your product characteristics and project budget.
Our company has developed different characteristics of thermistor, the main applications are: NTC thermistor, PTCR thermistor, PPTC self-recovery fuse, temperature compensated thermistor, power thermistor, using our advanced processing equipment, can also be assembled into different types of temperature sensors.
NTC Thermistor
NTC thermistor is a metal oxide for the full mixing, molding, sintering made of semiconductor ceramic resistors, the main materials are manganese, copper, silicon, cobalt, iron, nickel, zinc and other metal elements, a thermistor having a negative temperature coefficient, the temperature rises the resistance decreases exponentially.
In Ya Xun, continuous improvement of transistor technology, thermistor research has made significant progress. NTC thermistor is widely used in temperature measurement, temperature control, temperature compensation and so on.
In order to facilitate the installation and application of customers, NTC thermistor has a different package: SMD seal, Glass sealed diode, epoxy resin, single-ended glass seal, SMD glass seal, enameled wire.
