TEC is the abbreviation of thermal electric cooler , which is utilized to cool and heat objects based on Peltier effect. In temperature regulation, TEC has many advantages of high stability, high reliability, no noise, and a simple structure with no moving parts. TEC has been widely used for controlling the temperature of laser system, air conditioner, water heater and computer CPU. However, it still has some shortcomings: low efficiency, low thermal power and high cost. For better use of TEC, P...(more)
NTC thermistor can be used as an electronic circuit component in instrument circuit temperature compensation and thermocouple cold end temperature compensation. When using the self-heating characteristics of NTC thermistor to realize automatic gain control, it can form a RC oscillator, which is used to delay and protect circuit. The resistance of the thermistor is related to the dissipating condition of the environment when the self-heating temperature is far higher than the ambient temperature,...(more)

NTC thermistor can be applied in many fields, such as temperature measurement and control, temperature compensation, surge current suppression, environmental measurement, etc. There are some common failures and causes for NTC thermistor 1. Short circuit: When theloop current is higher than Imax, or power rating is higher than Pmax for a long time, it will make the temperature of the thermistor higher than Tmax. At the start, the thermistor will have a rather low resistance, and then the thermist...(more)

NTC thermistor in series in AC circuit functions like current insurance. How does this insurance do in the circuit? When the circuit is powered on, there produces an instant surge current. Thermistors can suppress this current. After this, the current will keep stable, and then the NTC thermistor will decrease its resistance to an ignorable value, which will not influence the current. During power-off at room temperature, the resistance of thermistors is relatively high, and at the moment of pow...(more)
