describe

PTC ( Positive Temperature Coefficient ) is a thermistor material. PTC heating elements offer a range of advantages unmatched by traditional heating elements, including automatic constant-temperature heating, long service life, energy saving, no open flames, excellent safety performance, easily adjustable heating value, and minimal influence from power supply voltage . They can be manufactured into various shapes and sizes, with round, rectangular, and ring-shaped shapes being common.

Regular diameter of round
12mm/8mm/19mm/17mm/20mm/6.7mm/5mm.

Regular rectangular sizes include 10x6mm/32x12mm/30x18mm/24x15mm/30x10mm/17x15mm/30x6mm/13.6x10.7mm/10x28.8mm, etc.
