Jinke-Find Ptc Thermistors For Overcurrent Protection pptc On Jinke Ptc-8

The positive temperature coefficient thermistor (PTC), as a new type of over-current protection element, has been widely used in the user interface circuit of program-controlled switches in preventing high-voltage lightning strikes, alternating current lapping, etc. Thermistors (PTC) can be divided into two categories: organic polymer PTC and ceramic PTC. Organic PTC is formed by mixing polymer with carbon powder and extruding. The carbon powder forms a carbon chain to conduct electricity. When heated, the polymer expands, and the carbon chain breaks to form a high resistance. The ceramic PTC is made of barium titanate powder with positive temperature coefficient characteristics by high-temperature sintering through electronic ceramic process.

The main advantages of organic PTC are: the zero-temperature resistance at room temperature can be made smaller, suitable for series overcurrent protection and temperature fuses in power circuits with large currents. The resistance value changes quickly, the heat capacity is small, and the recovery time is short. . However, its biggest disadvantage is that it is determined by the organic polymer material and structural mechanism. After each flow impact, the resistance value increases and cannot be restored to the original value. When the high-voltage and large-current pulse impacts, the outer envelope is easy to burst.
