• High frequency performance of NFM18PS series
• Optimize of bypass capacitors using chip 3 terminal capacitor
Comparison of performance as bypass capacitor
Amount of parts can be reduced.
NFM18PS series has better high frequency performance compared to normal chip 3 terminal capacitors.
Effect
Noise suppression effect of NFM series is better than MLCCs. (1 NFM is better than 4 MLCCs)
