0402 SMD temperature measurement Chip NTC thermistor

Product Item: 0402 SMD temperature measurement Chip NTC thermistor
Category: NTC

  • PRODUCT DETAIL
There are three types of mainstream NTC thermistor structures on the market. If arranged according to the time of appearance, it can also be expressed as three generations of products.
• The first generation product is called block ceramic NTC thermistor, and the structure is as follows:
 Block ceramic NTC thermistor


The first product was a block ceramic structure. The ancient ceramic manufacturing process is used to make brick-size NTC ceramics, and then the precision wire cutting process is used to cut the ceramic bricks into the required package size. The first generation products are more suitable for manufacturing NTC products with pins and assembled structures, and are not suitable for making NTC products of the chip type.

• The second-generation product is called a multilayer ceramic multilayer NTC thermistor, and its structure is as follows:
 
Multilayer ceramic multilayer NTC thermistor

The second generation product structure is based on the MLCC manufacturing process. This product is a multilayer ceramic structure with internal electrodes, very similar to the structure of MLCC. It is also used to prepare ceramic flakes, then stack them to form a plate blank and then sinter, and finally sinter the NTC ceramic plate for precision cutting.


• The third-generation ceramic thick film NTC thermistor has the following structure:
 Ceramic Thick Film NTC Thermistor
The third-generation NTC thermistor products have undergone drastic changes in structure and manufacturing process. This product has a thick film structure. It uses a mature thick film manufacturing process, a layer of thick (30uM) NTC ceramic material is printed on the ceramic substrate, and then it is equipped with a special electrode structure and then sintered.
