Component 100 6U? On H340 circuit-board. Capacitor?

Addendum: 17 Aug 08  I could not save the 'old' board in my h340.  I took Bambi's advice, bought an h320 and did a 'parts swap.  I installed the hard-drive and case-back from the h340 on the 'new' h320.  All systems are working.  WE ARE ROCKBOXING!

I learned a lot from this thread, but tracking down a bad capacitor and troubleshooting the h340 circuit-board was not feasible, for me.  With h320's running around $100 US, investing more time or attempting to get the board repaired by a professional is simply cost prohibitive, IMO.  It only took 30 minutes to swap the parts, so Bambi's solution was the most practical in my case.

-----------------------------------------------------

Just North of the Data port on my h340 circuitboard (on the same side as the display) there is a black box labeled 100 6U -- Is this a capacitor?

I get continuity through this component when test it with my Ohmeter (the buzzer goes bzzzzz..)  Should this thing be passing current?

I can't find the 107 6.3V capacitors discussed in the Mistic River "Repair of Fried Player' thread.  That thread refers to the H120 and I'm wondering if the H340 uses a different capacitor arrangement.

The reason I'm asking is that I'd like to check if over-voltage damaged the circuit board of my h340 -- to see if that explains some of my hard-drive issues.

Does anyone know if 100 6U is a capacitor and whether it should pass current?

Or, are the capacitors controlling the input voltage elsewhere on the h340? 

My h340 started locking in 'charge mode' in the original firmware and Rockbox USB mode.  Not sure what else to look at.

Thanks!

saratoga:
Surface mounted capacitors used in DAPs are generally too small to have writing on them, although some are large enough to.  If theres writing, I'd expect it to be some sort of IC.

Feel free to post a picture though.

It seems like it's a capacitor but I don't understand the code on it.  This might be helpful: http://www.misticriver.net/forums/iriver-h1xx-series/44799-repair-fried-players-maybe-possible.html#post480099

This might explain the code:  http://www.dzsc.com/uploadfile/company/99723/200811416743914.pdf
100 is the capacitance in microfarads.  That is the same value as 107 in the more common code, meaning 10 followed by 7 zeros picofarads.
6 is the voltage
U is a date code, in that particular example corresponding to July 2006

bascule:
Well, if it is a capacitor, it shouldn't pass a DC current, so it may be fried. But if it is too small to be distinguished, it could be anything...

yapper:
Posting a clear picture would really help. My suspicion is that it's an inductor.
