whats the purpose of this white goo around capacitors?
Capacitors are held down onto the PCB by 2 wires that will snap off during testing if the weight of the capacitors wiggles the wire around too much while the board is vibrating due to the effects of the propellers. It''s a bad thing when pieces end …
The engineer''s complete guide to capacitors
This series examines the most popular types of capacitors and the most common capacitor applications to help you choose the most effective capacitor no matter your requirements. This guide is meant for any engineer …
Is a magnetron recoverable at home?
Quick answer on those cheap magnetron''s is no, the typical failure is the filament shorts to the copper block, though you do get a short circuit forming in the …

So I just got a little shocked by a capacitor
One thing is to know that a capacitor can get charged, and another one is to actually comprehend that a capacitor can get charged and shock you. My first question is: I …
What''s the white stuff on the capacitors? Is it a sign …
Nah they''re fine, that''s some sort of residue from the manufacturing process - note how it sits in concave and lower sections of the capacitor body, where it''s unlikely to be wiped off during handling.

whats the purpose of this white goo around capacitors?
In fairness, I have not seen this happen with this white compound but I''ve seen it several times where hot melt glue across connections or PCB traces turned …
Updated (I know): Why are my capacitors getting so hot?
The output was oscillating at 330Hz at 9Vp-p – so quite hard on the poor output capacitor. The load was a motor (270μH + 1Ω) and the output capacitor is 470μF – which I …

Electric...thing? We have been jokingly calling it a flux capacitor …
The capacitors appear to take in 120VAC in series (capacitors block DC, so I guess that rating isn''t what it appears to be), then pass it to the large coils, which could be …
Working on treadmill, What will a Bad Capacitor do?
The cream white stuff under the capacitor could be glue applied during manufacturing. If the capacitor gets hot, try replacing it, preferably with one with a higher …
Why is this capacitor covered in glue : r/AskElectronics
In laptop supplies and other high-component-density applications, it is sometimes used for reasons of electrical clearance. The electrical insulation of this stuff is better than air, so if a …
