NTC stands for Negative Temperature Coefficient, which means that the resistance of the material decreases as the temperature increases. An NTC thermistor is a type of semiconductor component made from metal oxides such as manganese, cobalt, nickel, and copper, using a ceramic manufacturing process. These materials exhibit semiconductor-like properties, similar to those of silicon or germanium. At lower temperatures, the number of charge carriers (electrons and holes) in the material is limited, resulting in higher resistance. As the temperature rises, more carriers are generated, causing the resistance to drop significantly. NTC thermistors typically have resistances ranging from 10 ohms to 1,000,000 ohms at room temperature, with a temperature coefficient between -2% and -6.5%. They are widely used in various applications, including temperature sensing, thermal compensation, and inrush current suppression. Their high sensitivity and stability make them ideal for precision temperature control systems and industrial monitoring solutions.
