Hi,
I am trying to identify a small ferrite core transformer with a centre tapped primary of 4 ohms total (approx .3mH inductance) and a single secondry of 1.2 ohm (approx 4.6mH).
From what I've been able to find out, I believe it has an 'RM Core' ... and is approx 15mm across by 10mm high.
I require 3 of them to repair some pcb's which are approx $700 each.
I've attempted to dismantle one, but it had been potted in some sort of rubbery material and there is no way it is going to come apart well enough to identify the way it's been wound.
If anyone could suggest where else these things may be used so I can see if I can find something suitable, I would really appreciate it.
There are a couple of photos of the device at the bottom of the attached pdf.
Thanks, Wes
