NTC (negative temperature coefficient) thermistor is a heat-sensitive semiconductor resistor. Its resistance value decreases as the temperature increases. The temperature coefficient of resistance is in the range of -2%/k~-6%/k, which is about that of metal. 10 times the temperature coefficient of resistance. Changes in the resistance value of the NTC thermistor can be caused by changes in the external ambient temperature, or can be caused by self-heating due to the flow of current. His various uses are based on this property. NTC thermistors are constructed from polycrystalline ceramics with mixed oxides. The conductive mechanism of this material is quite complex.

Introduction to SCD high power NTC thermistor:
NTC (negative temperature coefficient) thermistor is a heat-sensitive semiconductor resistor. Its resistance value decreases as the temperature increases. The temperature coefficient of resistance is in the range of -2%/k~-6%/k, which is about that of metal. 10 times the temperature coefficient of resistance.

His various uses are based on this property. NTC thermistors are constructed from polycrystalline ceramics with mixed oxides. The conductive mechanism of this material is quite complex.
Huaju Electronics is an early professional manufacturer of NTC thermistors in China. The NTC thermistors produced by the company are widely used in various handheld devices and miniaturized electronic equipment. They are also widely used in various temperature measurements and temperature compensation. In surge suppression and other occasions, the NTC thermistors produced by Huaju Electronics Co., Ltd. are low-priced and of high quality, and can completely replace foreign brands such as Murata, TDK, and EPCOS.
1. Product introduction
In order to avoid surge current in electronic circuits at the moment of power-on, a power NTC thermistor is connected in series to the power circuit, which can effectively suppress the surge current at power-on, and after completing the function of suppressing the surge current, Due to the continuous action of current passing through it, the resistance value of the power NTC thermistor will drop to a very small level. The power it consumes is negligible and will not affect the normal operating current. Therefore, it is used in power circuits. Power NTC thermistor is the simplest and most effective measure to suppress surges during startup to ensure that electronic equipment is protected from damage.
2.Application scope
It is suitable for the protection of conversion power supply, switching power supply, UPS power supply, various electric heaters, electronic energy-saving lamps, electronic ballasts, power circuit protection of various electronic devices, and filament protection of color display tubes, incandescent lamps and other lighting fixtures.
3. Features:
·Small size, high power, strong ability to suppress surge current
·Fast response speed
·The material constant (B value) is large and the residual resistance is small
·Long life and high reliability
·Complete series, wide working range
