standardising radial caps

(1 / 1)


This looks like a positive step. Any comments anyone.

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.
