High Reliability 20D9 NTC Thermal Resistor Strong Ability To Suppress Surge Current​

NTC thermistors are generally made of metal oxides such as manganese, cobalt, nickel and copper, and are manufactured by ceramic technology. These metal oxides are completely similar to semiconductor materials such as germanium and silicon in the way of conduction. When the temperature is low, the number of carriers (electrons and holes) of these oxide materials is small, and its resistance is high; when the temperature is high, the number of carriers (electrons and holes) of the oxide material is large, and its resistance is low.

The main advantage

1. Small size, no leads, fast response speed, small space occupied by electronic equipment,
2. Using three-layer electroplating process, it has excellent solderability and solder resistance, suitable for wave soldering and reflow soldering, and suitable for high-speed, high-density surface mount.
