It's the newly application NTC thermistor, which use for current compensation in christmas light strings. Its function is current compensation.
The schematic of protection open circuit for Carnival / Christmas lights with NTC thermistor, it wont increase the current cause the relative resistance of circuit current and each working resistance of bulb lights.
To avoid the current failure cause the original design, which the current increased by copper oxide. It can cut down the cost and more reliability if useing NTC thermistor for open circuit protection, the use life of Christmas lights string which use NTC thermistor over three years.
Feature:
*Glass sealed, water proof, more stable.
*Small size, light weight,firm structure.
*Usable in high-temperature and high-moisture environments due to the glass wrapping.
*Fast Response time.
*Operating temp. Range: -40 ~300C.
Applications:
-Temperature sensor.
-Induction cooker, micro oven, automotive.
-Current compensation.
