Weird capacitor...
Hi everyone
I need to replace a capacitor that decided to blow up on an extremely old XT 8088 motherboard. This capacitor looks like a tantalum capacitor and has the following markings on it: 106 16. As far as I know that means 10 microfarad and 16V (can anyone confirm ?). But there is something weird. This capacitor has three legs instead of two! I looked around the Internet to find an identical one, but tantalum capacitors with three legs don't seem to exist. Does anybody know what type of capacitor this is ? Is the third leg there just to hold the capacitor in place, or does it actually do something ? Any idea where I can find a replacement ? Thanks to everybody in advance. |

Thanks to everybody in advance. I have occasionally seen a 3-legged capacitor where the middle leg is just for mechanical strength. Norm |

@libero.it says... I need to replace a capacitor that decided to blow up on an extremely old XT 8088 motherboard. This capacitor looks like a tantalum capacitor and has the following markings on it: 106 16. As far as I know that means 10 microfarad and 16V (can anyone confirm ?). That is correct. But there is something weird. This capacitor has three legs instead of two! I looked around the Internet to find an identical one, but tantalum capacitors with three legs don't seem to exist. They exist, but I don't know of anyone carrying onesey-twosey quantities for repairs. The idea is for mass production it is impossible to install wrong. Unless the board designer did something really stupid like use the end legs' connection to form part of the circuit, you can replace with a standard 2 lead capacitor. |

Sorry for the silly question I am about to ask but I'm a newbie when it comes to electronic components If I replace it with a two-legs capacitor, how do I know which leg of the old capacitor is the one to be "ignored" ? And by the way, could it be a double capacitor ? Do double tantalum capacitors exist ? Thanks again |

Sorry I don't know how to do that What do I need ? tongue-in-cheek "Meter it out" is a technical term: It's when you use a meter probe, and apply too much pressure to a leg of a component while taking a reading, resulting in the component coming out of the board. Possibly in more than one piece ... At which point, the answer to second question is "Not any more ...." \tongue-in-cheek -- --------------------------------------+------------------------------------ Mike Brown: mjb[at]pootle.demon.co.uk | http://www.pootle.demon.co.uk/ |

If so, use a jumper wire to replace them. ISTR there were some safety capacitors like this. N |
