Appliance&Features
PTC ceramic thermistor has been wildly used in electric devices as temperature sensor to control local temperature.In such assembly, PTC should be fixed in proper positon such as damper windings so as to contact with heat source directly. PTC elements are usually connected in series in order to monitoring multi-points so that control units would receive signals of increasing resistance. We could provide both single and trio overheat protection elements according to cutosmer demands.
Temperature range for our overheat protection components: 90－180℃
Application Area of overheat protection components:
▲ Overheat protection for machine winding(single and trio)
▲ Overheat protection for transformer
▲ Overheat protection for high-power transistor
▲ Fixed temperature detector
Advantage:
1.Protected by insulation cover
2.Low resistance&high sensitivity
3.High-temperature insulated silvering wire
4.Range of temperature: 90－180℃
5.Environmental friendly
