Default Re: Capacitors. Is physical size important?

Over the last 40 years or so, electrolytics have become tiny in comparison to their 70's precursors.

There are still physically large types, low ESR 400VDC types available for e.g. decoupling low impedance high-speed switching circuits, taking big gulps of power out of a DC bus (pulse circuits), and these cost substantially more, but a component rated 40V and 6,800uF will be very small compared to its ancestor.

Small, but absolutely fine! As usual, you will find people trying to persuade you that a capacitor for an 'audio' role has to cost £40, but it's just profiteering!
