Multiple decoupling capacitor in parallel? -SOLVED
A 10 µF capacitor will filter low frequencies (60 Hz - 10k Hz) then it starts to loose its effectiveness and no longer decreases impedance with frequency. A 0.1 µF capacitor has minimal effect in the below 10K Hz range but above these frequencies it is actual more effective than the 10 µF capacitors, especially around 10 MHz and above.
