Heat Resistance PPTC Thermistor Stable Performance Practical

Small Volume PPTC Thermistor Stable Performance And Strong Overload Capacity

PPTC thermistors ((Polymer Positive Temperature Coefficient)) are made of polymer material filled with carbon black particles. This material has a certain ability to conduct electricity, so it can pass the rated current. If the current through the thermistor is too high, its heating power is greater than the heat dissipation power, at this time the temperature of the thermistor will start to rise continuously, and at the same time the polymer matrix in the thermistor starts to expand, which causes the carbon black particles to separate, and causes the resistance to rise, which very effectively reduces the current in the circuit. At this time, there is still a small current flowing in the circuit, and this current keeps the thermistor at a high enough temperature to maintain a high resistance state. When the fault is eliminated, the PPTC thermistor will cool down quickly and will return to the original low resistance state, so that it can work again like a new thermistor.

PPTC resettable fuse features:

1. The resistance temperature is high, ten to a hundred times larger than that of metal, and it is more sensitive to temperature changes;
2. The working controllable temperature range is wide, which is suitable for normal temperature devices, high temperature devices and low temperature devices;
3. Long working time and long service life;
4. Small volume, it can measure the temperature that cannot be measured by other temperature measuring devices;
5. The application and structure are simple, and it is very convenient to use. The resistance value can be arbitrarily selected between 0.1~100kΩ, and it can also be processed and produced;
6. Stable performance and strong overload capacity.
PPTC resettable fuse has a wide range of applications and can be used in various fields such as household appliances, automotive electronics, industrial electronics, power adapters, communications, and aerospace. It is an overcurrent protection component.
