It sings !

Incroyable.

hello there
I saw here few of you who use ICAR 50uf capacitors.I too want to order those caps 50MF SB25/R-FS-DECK - MULTICOMP - CONDENSATORE, 50UF, D-DECK STUD | Farnell Italia and i was wondering if they come with fixing system ?

 

[Marra]

The last time I bought studded caps they did'nt so you'll need some of these.

PYB7041 - KEMET - NYLON CAP NUT, M12 | Farnell United Kingdom

motor runs don't need isolation nut

 

[schultzsch]

they already have the fixing nut? i saw in the datasheet multiple fixing systems for those caps but doesn`t say nowhere if they come with anyone of them..I am a little bit confused

 

[Zen Mod]

all motor runs I saw are having either screw fixed on bottom , or slot mounting for same

in both cases , screw is isolated from cap (electrodes) itself , what's completely logical - they're serious professional devices , not usual audio mumbojumbo thingie

in case that these (linked ) caps are having slot mounting screws , it's normal to expect that you'll get screws along with caps

 

[AndrewT]

Some stud mounting capacitors have one plate connected to the stud/casing.

 

[Zen Mod]

not motor runs !

they're intended for mounting on (whatever gadget is in question ) case , which is always on safety gnd potential

 

[tinitus]

the special motor run caps are not stud mounted, are they ?

ahh, those in question are special 'lighting' caps
some plastic cased, some not
but all still appear to be 'dry caps' and with isolated can

are lighting caps good ?

hey, maybe they are the secret BlackGate caps

 

[Zen Mod]

certainly some Audiophool caps are just encased motor-runs

Motor-Runs !...........

.

Cheers.


Si.

ALL fully-insulated = No worries !!!

I hear motor-runs are hard to get, behind the Iron Curtain...
...mystery-buyer hoarding all available stocks...
...rumour has it; for Earth's LARGEST plastic PSU.

( I don't believe a word of it personaly...
...just another 'urban myth'...Mmmm...? )

 

[Zen Mod]

those black ones looks as motor start caps

nono in PSU , they're just bad electrolytics

 

[The Space Egg Corp]

Yep...!

They binned brother !

Si.

 

[sakellogg]

those black ones looks as motor start caps

Why are they a nono in a psu? And dose that include tube psu?

When you say bad.... Bad how?
Poorly made?
Don't last long?
Lower than spec?

Thanks for info.

 

[The Space Egg Corp]

Environment friendly, safe disposal...of course.

Si.

 

[The Space Egg Corp]

Hi dude

They WERE just 110volt electrolytics ( non-polar ( I think))
I did actualy chuck 'em in the back of the garage ( just in case ).

The white & silver ones are the polys.

Cheers.

RIFA PEH 200 has the stud screw tied to the cathode. That yields to a short circuit in the negative side of a +/- power supply if you connect it to PE of the chassis, how it is usually mounted. This will fry a diode bridge until break it in two. Lot's of smoke and cracks. I promise!




Pointing it out on the datasheet LOUD and clear? That's for sissies!

Mmmm...

Interesting...

Is the RIFA PEH 200 a motor-run ?

I don't think they would allow a motor-run like that in the UK...
...could be wrong of course !

Cheers.

Si.

 

[Zen Mod]

maybe they are , for some sissy UK motors
