2、产品注意事项
瓷介电容器的静电容量易受温度½响,由后面的温度特性曲线可知道:Ⅰ类产品的容易受温度½
响相对偏小,Ⅱ类、Ⅲ类产品容量受温度½响呈非线性变化,因此进行容量测试前要把产品在½标规
定的标准测试条件 25±2℃的环境下放½
2~4
小时后再进行测试。
Ceramic capacitor electrostatic capacity is affected by temperature, the temperature
characteristic curve of the back know:
Ⅰ
products easily affected by temperature is relatively small,
Ⅱ, Ⅲ
product capacity is affected by the temperature change is nonlinear, so the capacity test before
to product the standards prescribed by the national standard test conditions to 25 + 2
℃
placed
under the environment of 2 ~ 4 hours before test.
