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

<< < (16/64) > >>

nukie:
I have two 187 and a 189 of different manufacture batch. No leaky caps. No battery drain. Battery life has been great with Eneloops. I never have to worry about it.

I thought 187 doesn't have that cap ? See post #15.

nukie:
Yes I know 187s have no caps, what I mean was the 187s and 189 have similar battery consumption and I have replaced my 189 cap. It wasn't leaky or anything but it sure looks pretty rusty when I  got it last time.

BravoV:
Is that the new replaced cap ? I can see there is a (M) Mashusita logo on it, are you using the same type ?

Isn't that Mashusita brand product is no longer produced and replaced by Panasonic brand ?

nukie:
I bought it from rockby.com.au many years ago but it seems they don't have it anymore.

I bought some Panasonic FM, FR caps from Digikey recently they are still using the "M" logo. I have some bigger  EC series caps have the full "Panasonic" printed on them but the M logo would save them printing cost on caps that cost a few cents.

I found exact replacement here for $1

Disregard the specs on the webpage it's entered incorrectly the part no. ending with 104 is 0.1F

Capacitance: 0.10uF would not be a supercap. It would be a very poorcap.
