Fluke 189 with leaking surface mount supercap (also Fluke 287, Fluke 289)

<< < (3/64) > >>

About 6 years old I think

JohnDee:
To answer BravoD's question below, the supercap on my Fluke189 looks very much like the one in mikeselectricstuff's 287 picture below. 
The original Panasonic supercap (P/N EECEN0F204AK) is still available in the USA and Canada from Digikey, Allied and others but with a min buy qty of 2,000pcs.  May as well buy a new DMM...  However I did a datasheet comparison and ELNA P/N DSK-3R3H204T614-H2L (corresponding to Digikey 604-1147-1-ND at $2.81ea, no min qty) as suggested by tsmith35 below looks like a good candidate for replacement.  I will probably go with that one.

ElektroQuark:
What does FLUKE say about this?
Warranty?
;)

A huge high res photo of 287's gut -> Fluke 287 DMM Teardown and photos , although its not very clear whether its using Panasonic cap, can't identify the (M) Matsushita logo like Mike's.

Mike, looks like you need to de-solder that cap off, worry it will going to burst out the goo once the container structure collapsed eaten by rust.  |O


My two 287s are manufactured in Jan and April 2013, will open it up to see which brand, its very unlikely they're using Panasonic Goldcap like Mike's since Panasonic already discontinued that for a while.

BravoV:
My 287 is manufactured in April 2013 (Box label) with serial no 23780XXX.

The ultra cap's date code 1204 is also showing corroded sign, not as bad as Mike's though. Definitely not Panasonic (Matsushita brand) with that (M) logo like Mike's.   ???

Does this thing leak ?  Anyone knows what brand is that ?

Dave, this issue should be a good material for a short video blog.
