Am I right in thinking that a common mode choke such as this can be wired in two ways?
The normal way (according to the datasheet) is "both dots on the left". Used for noise rejection, and to prevent noise from the load being passed back into the PSU. Happy to be corrected. I believe in such mode the choke provides almost no inductance and therefore almost useless for power smoothing in a filament supply.
My question is, can such a choke be wired "top dot left, bottom dot right" so that it DOES provide inductance and in conjunction with a cap would provide some smoothing and ripple reduction?
