Product name: PTC sensor thermistor for over-heat protection

Item: MZ5 series

Details:
PTC sensor for over-heat protection

Brief Introduction:
MZ5 series as a temperature sensing 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 sensor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit with installed PTC sensor will turn on or cut off loop through resistance changing to achieve protection purpose.

Product application:
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

PTC Sensor Working principle:
As in Fig 2,in normal ambient temperature, PTC sensor thermistor resistance Rp

Advantages:
1.Small size and convenient installment;
2.Good stability
3.Wide protection temperature range:60-130 degree Celsius
4.Quick action
5.No resetting after over-heat protection
6.Wide application

Marking of Part Number:

1.Series: PTC sensor thermistor for overheating protection
2.R25 resistance:  101R<100Ω          331R<330Ω
3.Protection temperature:Ts:T100-100℃
4.Type: A-pin form       B-metal form
