Hi All Diys !
I have some Rubycon oil caps, and in one side of the cap is aluminium ,but the other side is insulated ,like in an Electrolytic cap,and my question is if i can connect it either way ,or does it have to be connected in a special way,like the aluminium side for input or output? Positive or negative ?
Thanks

It can go both ways, but...The aluminum side, the can that surrounds the cap, is usually connected to the source and the insulated end to the load. The can acts like a shield.

Thanks Semperfi... and i noticed the caps have some arrows,and now i know that indicates the path of the signal....didnt have experience with this caps before...

What are the voltage and capacitance rating of these capacitors? What's the approximate size of the can? That can style is unfamiliar to me in the Rubycon line.

If it's a polarized cap the arrow indicates DC polarity. If it's a nonpolarized cap the arrow indicates the inner foil connection. In some circuits sensitive to stray electrostatic coupling it may help with noise reduction to connect the outer foil side to the part of the circuit that has the lower impedance to ground, etc.

Thanks!

The can mesures 3 cm long ,the radius is 1,8 cm and there is a code
CP-C 29 ,and 0,22uf at 600 V .
Thanks
