temperature sensor ptc thermistor for protection from heat mz5 series-九游会下载

brief introduction of temperature sensor ptc thermistor:

mz5 series as a temperature sensor is in small size and low heat capacity,can display overheating situation of power components in switching mode 

power supply effectively.making use of the characteristics that the resistance of ptc thermistor increases sharply above curie temperature, 

when ambient temperature increases abnormally, protective circuit with installed ptc thermistor will turn on or cut off loop through resistance 

changing to achieve heat protection purpose.

product application of temperature sensor ptc thermistor:

1.switching power supply

2.all types of electricity machinery that work continuously such as automatic lathe,motors,electro-thermal oven,ball grinder etc.

3.transformers

4.power parts

5.fire alarm

working principle of temperature sensor ptc thermistor:

as in fig ,in normal ambient temperature,ptc thermistor resistance rp

advantages of temperature sensor ptc thermistor:

1.small size and convenient installment

2.good stability

3.wide protection temperature range
