These things pretend to be resistors - or worse, they sometimes pretend to be resistors! Only last night one nearly got me, but I'm wise to their evil ways now

Just to clarify, I wasn't referring to "tropical fish" capacitors - these are indeed very reliable. The ones I mean are ceramic discs - but unusually for a ceramic disc, they are square, and have 3 coloured lines to indicate their value. These lines don't go around the whole of the capacitor (like they do on "tropical fish" caps) - rather they are short strips on one side.
I'll try to remember to take a picture later tonight...
