LCDuino Supercapacitor

Postby Horio » December 1st, 2014, 11:57 am

The recommended supercapacitor (0.022F / 5.5V) does not appear to be stocked by either Mouser or Digikey anymore. Any issues going up to a 0.047F /5.5V supercapacitor? It looks to be just slightly wider (2mm) and a little bit taller.

Why not just use the Kemet NEC Tokin 0.022F one? (Mouser part # 80-FR0H223ZF). The 13.5mm diameter of the type F will probably interfere with U2 if my vernier calipers are to be believed. The Kemet is only 11.5mm diameter. For reference, the circle on the silkscreen measures 10mm.

BTW that's what's in my basket on Mouser, so if Ti says it's no good I'll have to rethink my build too.

Also look at Powerstor/Eaton KR-5R5H224-R or Elna DX-5R5H224U. The LCDuino-1 board also supports vertical mount supercapacitors, you just need to make sure there is enough rear clearance.
EDIT: nevermind, those are 0.22F rather than 0.022F. Go with the Kemet/NEC/Tokin FR0H223ZF. Due to its 14mm height, you'll need to mount it on the back side of the board.

The FR0H223ZF is on order at Mouser with a delivery date of next March, and Digi-key does not stock it.

Meanwhile you can find usable supercapacitors on ebay. Search for FYL0H223Z or FYD0H223Z. The FYL0H223Z can be mounted on the front side of the PCB due to its low-profile. The current ebay listings are in lots of 10 only, but they are inexpensive. You could also order the FYL0H223Z from http://www.circuitdiy.com for $0.65 each.

Just passing along info - I have no affiliation with these sellers.

Oops, sorry, the one I had recommended was in stock when I posted, but looking at the page (still open) it was only showing 2 in stock! I guess they sold them.

fwiw, you can do the build without it and add it later. of course its only purpose is to hold the RTC time during power failures. if you don't care about that, you can do the build and just leave the SC out until it comes back in stock again.

Thanks for the replies! I think I'll just go with the Elna supercap as there are plenty in stock at Mouser.

@Horio, which Elna? The one I mentioned is not correct as my edit shows.
See also KG-AMB's post above. Note that the supercap he links to is a 0.047F unit.
Panasonic EEC-S0HD223H (0.022F) is still available from Newark:

Hi, 80-FR0H223ZF leads don't fit LCDUino PCB holes. Not to mention height and diameter.
Can 0,22F cap (667-EEC-S0HD224H) be used instead of 0,022F?
667-EEC-S0HD224H still is in stock, while 667-EEC-S0HD223 is EOL.

EDIT: and what about some values in between, say 0,047F - 0,1F? They also seem to be in stock.
