Siemens MKV makes noise when shaken

12 Cents · 25th January 2005, 08:06 PM

Hello,

I have two Siemens MKV caps here, each of them making a little sound somehow like a can of coke when I shake it. Is this normal? They are B25834-K6475, Non-PCB, date code seems 11.94.

Regards,
luke

They are filled with oil.

ok, but somehow I thought they would be filled completely...? But ok maybe this is just normal production procedure.

this is the simple procedure to identify if unknown can-shaped-capacitors are oil filled.

Not really, some have a thick & greasy oil, MKV is very liquid...

BTW, I really like them as coupling caps.

But what should I do with MKV's that don't have the Non-PCB label? Can the PCB "dry out" of the cap causing desease? Shall I evacuate the house and call a specialist in the case that they explode??
