Hi All.
Currently I am working on a PCB design for a product which is relatively constrained in both board area and height. (Already using 0603 for resistors and small capacitors.) Currently I am working on the power supply section of the PCB and the placement of the larger (10uF) Decoupling capacitor, The issue that I face is that the top side of the PCB will only have a small amount of vertical clearance (<5mm) as a cover will be fitted over the top of the PCB, while it would be possible to include a cut out in this cover for the capacitor, I find that it may be more elegant to make use of a larger than usual ceramic capacitor and just eat the slight increase in cost.
Another option that I was originally considering is to place the capacitor on the bottom of the board, which is completely open, however this would lead to the capacitor being much further away from the power supply due to some nearby through hole pins.
Are there any hidden traps or reasons to not use large ceramics for decoupling? I understand that ceramics can have a micro-phonic effect, is this amplified at larger values?
Many Thanks.
