产品描述
产品规格及参数

　　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.

　　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 measurement and temperature compensation occasions. The NTC thermistors produced by the company are low in price and of high quality, and can completely replace foreign brands such as Murata, TDK, and EPCOS.

7. Precautions:
1). Do not bend the resistor wire frame at will to avoid causing the chip and wire frame to fall off and cause poor resistance;
2). The temperature during welding should not exceed 300°C, and the welding time should not exceed 0.5 seconds;
3) . Use a hot air gun when heat shrinking the sleeve, and the temperature of the air gun should be controlled at about 120°C;
4). When welding, use a constant-temperature soldering iron with a flat tip. Hold the resistor in one hand and the wire in the other hand for butt welding, which can improve production efficiency and shorten the soldering time. Welding time;
5). Special reminder: Do not touch the chip (i.e. the top of the resistor) with your hands!
