I have a couple of old Hammond 12S200 chokes. They’re swinging chokes with a rating of 4 – 21 henries @ 200 ma and with a peak voltage of 5K. Would it be safe to assume that they could used in a circuit of up to, say 400 ma, with a significantly lower voltage?
NO.
The current rating is a current rating.
It, combined with the size of the frame, the surface area, and the DC resistance …
Determines what the maximum current at “ambient conditions” you can safely use.
Nothing related to age.
Nothing related to “lower voltage”.
