(1/13) Conformity to RoHS Directive NTC Thermistors NTCG Series(SMD, Pb Free) NTCG06/10/16/20 Types NTC(Negative Temperature Coefficient) Thermistors are manufac- tured from sintered metal oxides. Each thermistor consists of a combination of two to four of the following materials: Manganese, Nickel, Cobalt and Copper. NTC thermistors are semiconductor resistors that exhibit decreasing resistance characteristics with increasing temperature. TDK thermistors have low thermal time constants which result in extremely high rates of resistance change to accurately track the temperature.
