Fast Response Speed 20D15 NTC Thermal Resistor Has Excellent Solderability And Solder Resistance
NTC is the abbreviation of Negative Temperature Coefficient, which means a negative temperature coefficient, and generally refers to semiconductor materials or components with a large negative temperature coefficient. The so-called NTC thermistor is a negative temperature coefficient thermistor. It is made of metal oxides such as manganese, cobalt, nickel and copper as the main materials, and is manufactured by ceramic technology. These metal oxide materials all have semiconductor properties, because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carriers (electrons and holes) in these oxide materials is small, so its resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases. The variation range of NTC thermistor at room temperature is 100~1,000,000 ohms, and the temperature coefficient is -2%~-6.5%. NTC thermistors can be widely used in temperature measurement, temperature control, temperature compensation, etc.
Uses of NTC thermistors:
1. Temperature compensation of transistors, ICs, and crystal oscillators in mobile communication equipment
2. Temperature sensing of rechargeable battery
3. LCD temperature compensation
4. Temperature compensation and sensing of car audio equipment (CD, MD, tuner)
5. Temperature compensation of various circuits
6. Suppress surge current in switching power supply and power supply circuit
