Component Cables use Coaxial Wire??

I need to get a 25-foot component cable for my HDTV home-theater setup. I have been looking around and is it true that component cables use 75 ohm coaxial wire in them? Or are there kinds that use rca-type wire and some that use coaxial cables but they both end in rca plugs?? Thanks for your help!

RCA plugs and sockets are 50 ohm
BNC plugs and sockets are 75 ohm

If your equipment uses RCA plugs and sockets then you might as well use 50 ohm audio cable as it is unlikely to make any diff.

BNC plugs can be 50 or 75 ohms two types are available, most RF equipment is 50 ohms, video 75 ohms.

Phono or RCA plugs are not 50 ohm or 75 ohm they are normally around 55-60 ohms, some manufacturers claim to have made 75 ohm 'type' plugs but in any case the mismatch is minor in comparison to the length of the cable.

You should always use a 75 ohm coaxial cable for video irrespective of the termination on the end.
