| Capacitor that looks like a resistor? |

| Skyfox:
While I'm not a noob when it comes to electronics, this is definitely a beginner question because I've never noticed this before. Attached is a photo from the motherboard in my Commodore 64. I have to do some troubleshooting and repairs, and noticed this component. It looks like a resistor, has colored stripes like a resistor, but has a green body as opposed to the traditional beige of neighboring resistors and is in spot marked for a capacitor. The service manual indicates this is supposed to be an 82pf cap with 5% tolerance, which the gray-red-black-gold seems to indicate. I had a very hard time finding consistent color coding charts, at least when it comes to the tolerance. Some charts show gold at 5% tolerance, and others show no tolerance indication for that color. I take it the white stripe is supposed to be the voltage rating, but one chart shows that's 3 volts while another chart shows that's 900 volts. There are a few others like this on the board of various ratings. Anyway, is this in fact an axial capacitor? Certain other sources show axial inductors with a green body and stripes like this so I don't know how I'd tell them apart. And does anyone have a reliable color coding chart for this so I know what the colors in the tolerance and voltage lines are actually supposed to be? Thanks! |

Looks like a capacitor according to this schematic. |

There are such capacitors. Skyfox Your capacitor is 91pF. |

Axial capacitors.I've see a few of these but never really looked at the construction.Are they a wrapped film or cylindrical? |
