PTC (Positive Temperature Coefficient) refers to the characteristic where the electrical resistance value changes by a positive coefficient as the temperature increases. The "characteristics of PTC" are: ● When the temperature is low, the chain of conductive particles connects, making it easier for current to flow. ● When the temperature rises, the semiconductor terminals expand, breaking the chain of conductive particles and making it difficult for current to flow. By utilizing this characteristic, it is set so that the temperature does not rise further once the set temperature is reached, making it a surface heating element that excels in "energy saving" and "safety." PTC has the characteristic of controlling and maintaining temperature and power consumption according to the surrounding environment and heat dissipation, so it maintains the set temperature, reduces running costs, and does not overheat. —- Parrot, Cockatoo, Reptiles, Turtle, Lizard, Java Sparrow, Hamster, Guinea Pig, Rabbit, Squirrel
