Subject: Aluminum Electrolytic Capacitors
Can anyone provide info concerning the use of aluminum electrolytic capacitors in a controlled, benign environment? From past employers in the defense/aerospace industry, we always avoided these capacitors due to possible outgassing, creating a fire/explosion situation if a spark occurred. This was over 10 years ago, though. Has the technology of these capacitors changed and are they safer to use? Appreciate any help you can provide. Please e-mail to me as well as respond to this forum. Thanks again.

I refer to Bruce Dudley's response, is the approval(for use in airborne conditions) applicable to all manufacturers or only certain manufacturers? Would I be able to find any technical reports that show all Al Electrolytic Capacitors are safe to use in airborne conditions or list of approved manufacturers? If Al Electrolytic Capacitor is fully potted, will it be safer or more hazardous? Will the potting cause the safety vent unable to release internal pressures ? Thank you.
