热敏电阻的B值重要吗?

Is B value of the thermistor important?

First is to look at the science and technology, passive components thermistor applications, whether using harsh environmental temperature or general environment, are very emphasis on the selection of B value, usually take 25 ° C - 50 ° C and some high temperature such as microwave ovens, must ask B value in the range of 25-200 degrees, 100 degrees to 100 degrees that I have ever seen the B value, in this manufacturing thermistor its difficult.General domestic factory B value is 25 ° C - 50 ° C, we are all 25 ° C to 85 ° C and 300 ° C.The difference in the manufacturing process and technology.

科技-被动元件热敏电阻首要是看应用场合,不管是严苛环境温度或一般环境下使用,都要很注重B值的选择,一般是取25°C - 50°C 而一些高温的比如微波炉,就必须要求B值在25度-200 度的范围,我见过100度到300度的B值,可想而知制造热敏电阻其高难度在此。一般国内工厂的B值是25°C-50°C,我们都是25°C-85°C甚至于300°C。其差别就在制造工艺及技术了。
