All of us have seen them – maybe used them too. And we theoretically know what’s inside them, but how many have cut open to see what’s actually inside?
The victim : A 4.7uF electrolytic Capacitor rated for up to 400V operation.
1) The external sheath
2) Terminal hold
4) Aluminum ribbon
5) Paper soaked in Dielectric
The operation procedure :
Cut open the plastic coating which acts as a label as well as a protective sheath. use any sharp object. I used my teeth.
The aluminum canister housing the metal sheets is now exposed. Cut it off with any metal cutter. I used my tested wire stripper – teeth wouldn’t work.
You’ll see two tightly woven aluminum sheets. The terminals at the bottom of the capacitor are connected to these sheets. Sandwiched between the sheets is a kind of brown paper impregnated with a dielectric of gel-like consistency, sticky to touch.
In this case the victim could not be restored to its original state :( .
This was a very basic demo of things to come.
