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.

Ordering Guide
B value range: 3000-4600 B value accuracy: less than ± 1% B (25/50) Resistance range: 1K-500K, resistance accuracy (25 degrees) ± 1% ± 2% ± 3% If the user needs to specify the resistance value at a specific temperature between -30°C and +150°C, it should be stated when ordering. When the parameters and dimensions of the epoxy components ordered by the user are not within the above range, further detailed instructions must be provided. When the user cannot explain the component parameters, he or she can provide samples or RT tables of the components currently used. Be sure to find out whether customers have special requirements for components Delivery cycle: 20 days--30 days model
