Filter choke specs

Hello,
Can power supply filter chokes be used beyond their stated current
ratings? Are they typically rated for continuous duty? If so, if used in
ICAS service can I draw more current than rated?
For example, I have a choke rated for 5 Henries at 400 MA (25 Ohms). I'd
like to use it in a circuit drawing up to 650 MA peak. This would be for
a class C amp -- CW only.
Thanks for any input.

If the choke ratings are actually CCS (and not ICAS as many were/are), I
would go for it. If it doesn't quite work out, and the smoke bothers your
eyes, there is another easy solution. Since this is about homebrew, it is a
relatively simple project to rewind a choke (except, horror of horrors, a
potted choke). Use a little heavier wire. Since there probably won't be
enough
room for as many turns, you'll lose a little inductance, but who will know
the
difference? A little hum on a CW signal is quite distinguished anyway.
