EMI Suppression Effect
!Example of IC Protection
" Testing Method
1. Put ESD surge to IC (7404 family) input terminal with
ESD simulator based on IEC 801-2.
2. Check IC's operation.
3. If IC's operation is normal, increase ESD voltage in 1kV
step.
4. Continue above steps 1 to 3 till IC's operation becomes
abnormal.
