Electrical – Why 0.1u decoupling capacitors

capacitordecoupling

Why is always prefered the value of 0.1u as decoupling capacitors that they placed very close to the chips?
Why don't use larger, like 0.22u, 0.47u, 0.68u or 1u for example?

Best Answer

0.1uF capacitors may attenuate higher frequencies better than, say, a 1uF capacitor due to larger (SMD) capacitors having more inductance.
