[Amps] Computer Grade Electrolytic Capacitors vs. Radial (score: 1): Author: ko4nrbs@yahoo.com (Bill Smith); Date: Wed, 4 Sep 2002 11:47:29 -0700 (PDT); I was give 12 radial 450 vdc 220uf capacitors and was wondering if they were ok to use in a HV power supply. What would I gain if I spent the extra money for the computer grade? Are the radial types; /archives//html/Amps/2002-09/msg00027.html (8,048 bytes)
