There are several general classifications of thermistors
There are several general classifications of thermistors：
A. Classified by temperature variation characteristics - positive temperature coefficient (PTC), negative positive temperature coefficient thermistors.
B. Classified by sensitivity to temperature changes - high sensitivity type (mutation type), low sensitivity type (slow change type) thermistors.
C. Classified by heating method - direct heating thermistors, side heating thermistors.
D. Classified by structure and shape - various types of thermistors such as circular (sheet), cylindrical (cylindrical), circular (gasket), etc.
The most common names for thermistors are PTC thermistors and NTC thermistors. So what is the difference between these two types of thermistors?
1、 PTC thermistor
PTC thermistor structure - made from materials such as barium titanate (BaTiO3), strontium (Sr), zirconium (Zr), etc.
PTC thermistor characteristics - the resistance value is directly proportional to the temperature change, that is, the resistance value increases as the temperature increases. At room temperature, its resistance value is small, only a few ohms to a few tens of ohms; When the current flowing through it exceeds the rated value, its resistance value can quickly increase to hundreds to thousands of ohms or more within a few seconds.
PTC thermistor function and application - widely used in the demagnetization circuit of color televisions, the starting circuit of refrigerator compressors, and circuits for overheating or overcurrent protection. It can also be used in small household appliances such as electric mosquito repellents and curlers, electric heating pads, and heaters.

Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
What Is The Difference between Resettable Fuses and Traditional Fuses?
PPTC and fuses both do the same job: protecting electronic circuits from overcurrent related issues. The difference is that the fuse must be replaced after tripping, while PPTC can reset itself. PPTC can handle sudden overcurrent events without the need for replacement.
Technical Standards for Fuses
PPTC thermistors should be packaged according to zero power resistance levels, and the resistance range should be indicated on the outer packaging.

The Application of Socay NTC Thermistors in The Field of Temperature Measurement, The Temperature Measurement Range of Thermistors Can Reach -40 ℃ to +125 ℃
NTC is a negative temperature thermistor, whose principle is that the resistance value decreases as the temperature rises. It is usually composed of 2 or 3 types of metal oxides, mixed in a fluid like clay, and forged into a dense sintered body in a high-temperature furnace. The packaging size is diverse, and they can be as small as 0.01 inches or smaller in diameter. There is almost no limit to the maximum size, but it is usually suitable for sizes below half an inch.
