I have seen ring files containing transparent plastic pages with small compartments in them. These spaces hold electronic components (Resistors, Ceramic Capacitors, Electrolytic Capacitors). Each page consists of a lot of components in these separate compartments on these pages. The compartments are closed with plastic lids.
It seems that this is the most compact and mobile way of storing all the resistors and capacitors instead of buying a storage cabinet with small drawers and the components separately. The only problem is that I can't find them on the internet. Does anybody know where I can find these component files? I am sure just 1 file will contain all values for a given series.
