| 429302 | 2006-02-12 01:20:00 | Yeah, I just desoldered it. Its 10 volts and 1500uF | bob_doe_nz (92) | ||
| 429303 | 2006-02-12 02:54:00 | Oki Doki, I've just decided to get the following capacitors to replace those crappy LAC's Code: RE6304 1000uF 10V Code: RE6306 2200uF 10V Big thumbs up :thumbs: to GrahamL and Goddie |

| 429304 | 2008-05-22 23:59:00 | Hi. I have replaced aii caps on 80 P4 Mbs. and had no problems, you have to have a good soldering station and and patients. At the moment I am trying to find 25 1800 too 2000uf caps that are 8mm dia. for 6 P4 compaq boards. any suggestion's. thanks Leslie | leswood (9787) | ||

Prob a bit better to start a new thread so are the OP and people looking will see your Post/question first. I see some 25 2200UF might be close enough www.jaycar.co.nz |

| 429307 | 2008-05-23 04:32:00 | Hello, welcome to 2006 :p My brother salvaged a discarded geforce card which was thrown away because the capacitors were leaky. He replaced them and he pretty much scored a geforce for free. Don't the uF ratings have to be exactly the same? Its obviously safer and more reliable if they are. The only matching capacitors my brother had were quite tall, which made the graphics card out of spec (as the cap was too high), but he didn't have anything in the slot underneat so its ok. |

| 429308 | 2008-05-23 05:44:00 | They don't have to be exactly the same, but it's not good to change the values too much. Voltage rating should be same or higher than the originals (but not too high - running a high-voltage rated cap at a significantly lower voltage is bad for it) capacitance should be the same but close enough will usually do (besides some have up to 20%+/- tolerance so their values may be a bit different to what's on the label!) so if you had faulty 1200uf but all you had was 1300uf for replacement it would be fine ;) The only time you could get away with signifcantly different values would be if you know the exact circuit, eg: if you had 4x 2200uf in parallel you could replace with 2x 4400uf and you'd be fine because the total capacity would be 8800uf either way |

| 429309 | 2008-05-23 06:47:00 | bob_doe_nz, how did you get on with that board? I fixed the mobo. And sold it after three months use. |

| 429311 | 2008-05-25 04:05:00 | ... it's not good to change the values too much. Many electrolytics have a stated tolerance of 20 - 50%. If a replacement one physically fits, and its voltage rating is high enough, it's fine. The capacitance doesn't have to be the same: they are power supply smoothing devices; not parts of a tuned circuit. Within reason, more capacitance is a b]good[/b] thing. (Far too much is not so good ... the initial charging current can be a problem ... but in general, one that's got far too many microfarads won't fit). The odd values 27, 33, 47, etc, are not random; they are carefully chosen to allow normal production variation. One that's at the top of the allowed range for one value will be at the bottom of the allowed range for the next value. |
