What I really want to know is, was the component faulty, or was it something I did..
having it plugged into a standard ProCell 9v battery on about 5 different occasions, one of the capacitors ..... exploded when I plugged the battery into it
If its just the cap you could use should desolder the remains and either replace it (10uF) or use a decoupling capacitor off the board - depending on how good your surface-mount soldering skills are.
Are you saying nothing had changed between the successful connections and the explosion? On the occasions it did not explode (I can't believe I just wrote that) did it work as expected or was it dead?
... did it work as expected or was it dead?
but I may have caught the pins the wrong way at some other point...
Quotebut I may have caught the pins the wrong way at some other point... That might have damaged the capacitors causing a short in them. This then would have been enough for it to over heat and explode when it was connected the right way round for a little time.In over 40 years I have not known a capacitor explode for no reason, it is more likely you damaged it than it was faulty to begin with.
