SCCE temperature measuring NTC thermistor chip

The thickness of the SCCE series welding chips ranges from 0.25 mm to 0.45 mm, and the size ranges from 0.80 mm to 2.0 mm. They are mainly used to make thermistors (thermal components, temperature sensitive components) encapsulated in epoxy resin (or other insulating sealing materials). sensor). SCCE series welded thermistor chips are produced using the most mature high-temperature solid-phase technology. Powder preparation, high-temperature sintering, slicing, electrode preparation, analysis and testing are all made with domestic leading high-performance equipment and company-made special equipment. All The raw and auxiliary materials and electrode silver paste are all made of high-purity environmentally friendly materials, which are purchased from well-known manufacturers at home and abroad. The channels are stable and the quality is controllable.

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.

　　SCCE series welding chips are mainly used to make epoxy encapsulated (or other insulating sealing material) thermistor chips. The chip is the core component of the thermistor (thermal element, temperature sensor). The accuracy, reliability, consistency, and long-term stability of the thermistor mainly depend on the quality and performance of the chip.
