This looks like a positive step. Any comments anyone. Pat. From: KIM::HUBBERSTEY 28-JUN-1990 18:34:08.89 To: MCCARTHY CC: HUBBERSTEY Subj: Radial vs. axial capacitors I talked with Don Wrightnour about what is and isn't auto-insertable and he said that the machines can only handle up to 0.8" lead spacing. The 47uF axial capacitor we currently use, 124009-476, has a PCB footprint larger than this and so can't be auto-inserted. Don also said that where hand insertion is required, his preference is for radial components. So . . . I am going to standardize on a 25 volt radial unit, 123015-476, for future designs. I'd also like to suggest that we standardize on a few voltages for electrolytic caps since the board space and cost differences usually amount to pennies and it would mean stocking fewer parts. 25 volts is a good number for general use since it gives at least a 30% working voltage margin in most of our audio circuits.
