Abstract
The EMI countermeasure components such as capacitors and ferrite beads are used for the power supply line of the IC to reduce unnecessary radiation. When a countermeasure component is arranged on the actual circuit board, a surrounding environment and so on has an influence, and it's difficult to evaluate the countermeasure effect in a good reappeared manner. So, we examined the evaluation method for components applying the standard of the radiation measurement for IC.
