Film capacitors

On my previous design, I made a total newbie mistake: putting tantalum capacitors directly on signal paths. This was quickly caught by one of the experts who is advising me on the project, and I’ve decided to replace them with film capacitors. Unfortunately, the ones we need must have a 220 μF capacity, which is a lot for a film capacitor. As a result, their individual size is 28.0 × 42.5 ×  41.5 mm, which is too large for our small ADC modules. Therefore, we’ve decided to mount them on the backplane instead. We will most likely use EPCOS film capacitors. Updated design coming soon…
