Hi Erik,
Madisound and Parts Connexion will have CMR & CSA in stock soon. I can provide free samples to substantiated manufacturers. I run an occasional group buy for hobbyists and smaller OEMs who need custom values or can’t justify factory MOQs.
Since the surface area of the end spray increases with diameter, the benefit of coppering the ends is greatest with the higher value caps. This led us to shift catalogued aspect ratios toward larger diameters and shorter lengths. In turn the narrower metalized film stock employed further reduces ESR. The downside is that fatter caps may not fit in some applications.
