Re: Ryobi 36V (aka 40V) 6Ah Faulty Battery Pack
Thanks for the detailed comments!
This battery pack is now pulled to pieces (beyond repair) since last night!
I decided to remove all of the packs cells and measure their individual voltage. Problem was the cells were well "hidden" within the plastic enclosures (holders) and with conductive metal strips spot welded to each end of the cells. So in order to remove the cells, I had to literally rip off the metal strips and unscrew and tear off parts of the plastic cell holders. In the process of...

Re: Ryobi 36V (aka 40V) 6Ah Faulty Battery Pack
I forgot to add that the battery pack voltage as measured via the negative PCB pad and the positive pack terminal has now reduced to only 2V !!!?? Initial charge voltage was around 34.5V yesterday. So there seems to be some serious discharging going on inside this battery pack!Leave a comment:

Re: Ryobi 36V (aka 40V) 6Ah Faulty Battery Pack
All comments noted, thanks!
So the five inline holes marked from SWDIO down to GND is the interface for programming the microcontroller.
As mentioned in my initial post, there are no other "RESET" markings apart from the RESET hole within the 5 inline holes (for programming). Also there is no "RST" marking on this circuit board anywhere for specifically resetting the BMS. Some Ryobi battery pack circuit boards do have a "RST" hole together with an adjacent hole (which may...Leave a comment:

Ryobi 36V (aka 40V) 6Ah Faulty Battery Pack
Purchased a Ryobi 36V 6Ah battery pack maybe just over a year ago.
Battery pack had been used on about 3 or 4 occasions for powering a cordless lawnmower. I was wanting to use this battery pack again recently, but on checking the battery charge state via the battery pack test button, there was no LED indication at all of charge state which suggested the pack was fully discharged.
I found this to be odd as I usually fully recharge battery packs shortly after use. So either the pack developed some sort of fault which completely discharged the pack cells (after recharging),... -
Re: Post help identifying capacitors here
It appears to be a Partsnic capacitor.
There doesn't seem to be a valid website for this manufacturer, but details of many of their capacitors (including this FHX series) can be found [URL="http://www.paullinebarger.net/DS/Daewoo-Parstnic/"][b]here[/b][/URL]Re: Post help identifying capacitors here

Re: Resistance value
OK. The resistor color code appears to be -
brown
black
silver
gold
But the problem is you can't have two tolerance values on a resistor as denoted by silver and gold. So the "silver" looking band is probably meant to be "grey" (the resistance value multiplier).
So the resistance seems to be 1,000,0000,000 ohms (that's 1 Gohm) with a 5% tolerance.
However, if the silver is actually silver (and not grey), then the resistor value seems to be 0.1 ohm at 5% tolerance!

Re: Post help identifying capacitors here
Capacitor from a MSI card I believe. Card part number unknown, although as far as I know there is only one version of this card from MSI.
Partly by chance by searching on the internet, I now suspect that this capacitor is customized for MSI and possibly manufactured by Apaq.
Apaq have an EA series of capacitors with markings similar to this capacitor in question. But the standard EA series capacitors are marked in red color, and also include Apaq "eye" logo at the beginning of the second line of text/marking....Leave a comment:

Capacitor from a GTX 1070 Ti card.
Elite capacitor? Maybe, but EA(X) series not shown on their website. Unless capacitor is discontinued, or maybe capacitor is custom made (by Elite)?Leave a comment:

The markings on this capacitor look vaguely familiar, but I haven't found the manufacturer of this capacitor (yet). Capacitor from video card.
Who manufacturers this capacitor?

Re: ASUS ROG STRIX GPU capacitor manufacturer
Can't positively identify any of these capacitors.
There is no definite match to known capacitors from known manufacturers.
However, as is fairly common these days, many capacitors are manufactured specifically for OEM's, particularly those that manufacture motherboards and video cards. As these capacitors are special ordered, there is usually no public information available for these capacitors, unfortunately.
So, it is likely these capacitors are custom ordered, with no information on them being...Leave a comment:

Re: need help identifying caps on a video card again: emTek HV Geforce GT 220 Prime
The capacitors marked with the voltage, capacitance, and the batch/lot code only (and all printed in that order), are suspected to be custom made. There is no known manufacturer that produces such capacitors as part of their regular capacitor series.
Since these capacitors are (apparently) custom made, there is no data sheet publicly available. Plus the manufacturer is unknown anyway as there are no logos, names, initials, or series marked on these capacitors.Leave a comment:

Re: Problem with LG LW40 Express
This is a Panasonic tantalum capacitor from the TQC series. Capacitance is 22uF at 25V. Google for replacement sources.Leave a comment:

Re: Reqd Date Decoder for Rubycon Electrolytic capcitor
Not entirely certain, but the letter usually indicates manufacturing location.
The "08" indicates the year 2008.
And "06" and "12" usually indicate the week of manufacture.
So 3M0806 capacitor was manufactured in week 6 of 2008, and A0812 capacitor was manufactured in week 12 of 2008.Leave a comment:

Re: PNY 6800GS unknown caps
For future reference, these unknown capacitors are, I believe, Rubycon TZV series.
The BE capacitor is rated at 25 V, and the BF capacitor is rated at 16 v. Both are 100 uF.Leave a comment:

Re: Identifying capcacitor.
I know this is an old thread, but for future reference I believe the capacitors are Nichicon PCF series, 220 uF at 16 V. Manufactured around June 2008.Leave a comment:
