![]() You sir are a genius. I was going to check the capacitor but you beat me to it!

![]() Alright, so after doing some searching on the forums here I have gathered quite a bit of knowledge. Man you guys sure know what you're doing. I need your help yet again.
My TDK inverter board has three Taicon HD series caps but I have looked up and down Taicon's site and I can't find the spec sheet for it anywhere. In fact, the HD series isnt even listed on their site. I found this thread that references the HD series but no spec sheets: http://www.badcaps.net/forum/showthread.php?t=122 I'm tracking down the remaining caps from the power board now. I will report back once I have rounded them all up. Last edited by thewzard; 06-05-2011 at 09:45 PM.. Reason: Forgot to mention something |

![]() In the thread I mentioned above, someone said something about Nichicon still making this cap and I found a similar Nichicon cap but I'm not 100% certain. I need someone's input on this.

![]() Different manufacturer. NOT the same product. Some manufacturers have the same series codes. Do not be confused that one is the same as the other.
Dimensions, capacitance, voltage of inverter board Taicon HD caps? Last edited by Toasty; 06-05-2011 at 10:06 PM.. |

![]() Taicon is a part of the Nichicon family. Thats why I thought there might be some truth to that statement. Anyway, you would know better than me.
TAICON 35V 220uF ~10mm diameter ~12mm height 105C(HD)P C0621(M) |

![]() Alright so this is what I have come up with for the power board. This is as far as I can go for today. I cannot find the FDAI brand anywhere and I can't pull the specs from ELITE's site from any browser. Hopefully Elite's site will work better tomorrow. Has anyone heard of the FDAI brand?
EDIT: I took toasty's link from earlier (http://chinsan.co.th/files/PW.pdf) and altered the link to reflect the different series (http://chinsan.co.th/files/ES.pdf and http://chinsan.co.th/files/EJ.pdf) and it worked!! All I'm missing to complete the power board is to figure out the FDAI mystery. FDAI (I think) 50V 47uF U32 105C CD112A Picture available if necessary Measurements not available* Jamicon 100V 1uF TK P105C 624C2(M) Picture available if necessary Measurements not available* Elite 35V 470uF EJ(M) 105C (C)0616 FET Picture available if necessary Measurements not available* Elite 25V 220uF ES(M) 105C (C)0620 FET Picture available if necessary Measurements not available* Elite 450V 120uF PW(M) 105C (C)0623 FET Picture available if necessary Measurements not available* *I felt confident with this process and I didnt measure the caps. I now know that it was a foolish mistake on my part but it was partly because of the trouble im going through to get the measurements. My ruler wasnt made for this, its long and bulky and the measurements don't begin at the tip of the ruler. What are you guys using to measure? Last edited by thewzard; 06-05-2011 at 11:06 PM..

![]() While Taicon may be part of Nichicon, the series HD may or may not cross "family" lines. Information is sketchy at best.
There is no known Taicon HD datasheet "in the wild", so it's very difficult to compare. While the Nichicon HD's may prove to be a good match for this application, I'd be more inclined to go with some better series'. A toothpick, straw, or q-tip stick makes a good measuring device. You can mark it off every 5mm or so and get a pretty good idea of sizes. Your "standard" #2 pencil is nearly 8mm in diameter. A penny is 19mm and a quarter is just over 24mm. Look at some various brand caps datasheets and notice the standard diameters of 5, 6.3, 8, 10, 12.5mm. Same with heights, but height is -usually- not a big deal unless the cap is crammed into a really small area. Diameter is the bigger problem as many are typically crammed tightly together. Replacements may be difficult to find in a particular diameter and is the chief complaint when trying to replace caps. i.e.- The manufacturer put it out in 8mm but you can only find 10mm replacements. FDAI picture please. Toast Last edited by Toasty; 06-05-2011 at 11:24 PM.. |

![]() Okay I get it, its not a perfect process is what you're telling me. Sometimes you need to substitute one for another. Well, so far I have been pretty fortunate. I have found suitable replacements for all of the power board caps without too much trouble.
This guy is the only one that still eludes me. I cant find the manufacturer to get the ripple current specs. ![]() U32 might be the series? ![]() I guess, going by what you said earlier, the only thing left now would be to go with the specs I have (50V 47uF) and get the best quality, highest ripple effect on digikey.com. |

![]() Alright so I've got the power board down. Here is what I've got, maybe someone can confirm that I didnt completely mess this one up.
2x FOAI 50V 47uF U32 105C CD112A Size: 6.3x11 RC: 145mA Replacement: http://bit.ly/kZvfnG 1x Jamicon 100V 1uF TK P105C 624C2(M) Size: 5x11 RC: 19mA Replacement: http://bit.ly/iLWoWd 4x Elite 35V 470uF EJ(M) 105C (C)0616 FET Size: 10x30 RC: 1300mA Replacement: http://bit.ly/mrOCOz 1x Elite 25V 220uF ES(M) 105C (C)0620 FET Size: 8x12 RC: 730mA Replacement: http://bit.ly/kL2eRU 1x Elite 450V 120uF PW(M) 105C (C)0623 FET Size: 18x45 RC: 740mA Replacement: http://bit.ly/iJTwAG Now I just need to figure out this Taicon HD series problem. I'm going to grab the best 35V 220uF caps I can find that will fit the space. |

You have a monitor made in China with shit caps in it. Those shit caps lasted 3-4 years then failed. If the caps are that shitty, who says they were anything even close to the published specs??? The specs were probably just made up by the marketing dept. to be close or better than the competition's caps. Use a known good manufacturer/series and call it done. I "blindly" use Panasonic FM or FC in monitors and never give it a second thought.

![]() The Panasonic FM's are fine for the Taicon HD and 2¢ cheaper than the Nichicons.
All the other choices look fine. Good Hunting! Toast |

![]() Yeah, and when the ripple burns out the GPU, we'll see then won't we...

The problem is that while the caps may have been good when the board was manufactured, they don't stay that way. And endurance testing is very difficult (expensive!!) to do in an accelerated time frame. PlainBill |
