As a result, high-frequency noise is generated when inductance and stray capacitance of the wiring of board or inside IC resonate due to a sudden change in input current. The high-frequency noise can conduct to external circuits and cause abnormal operation of the set. This Solution Guide introduces examples of noise countermeasures using a three-terminal filter (feed-through filter for power lines) with low ESL, which is effective for noise countermeasures against noise generated on the input side of DC-DC converters.
