Default Common-mode choke before or after?

Hi
In various schematics of DHT filament, commom mode choke is using.
Can I use with Tentlabs modules?
And if I can where to put, before rectifiers diodes or just before filament?

I don't know of a reason why you should not be able to use it with the Tentlabs modules.

If you have sufficient voltage the best place would be right after the rectifier so that you would have choke input.

Others report good results with a choke just before the filament.

Why not try the various options for yourself and report back to the forum?
