Hello LF group,
I am trying to make a list of toroid core material that is suitable for
136kHz power applications, for impedance transformers and low-pass filters.
I would appreciate any information about the material (brand-type), the
application (transformer or filter) and the power level it was used/tested.
many thanks in advance,

Hi Rik,
matching the 136kHz PA output from 3,5 Ohm to coax cable 50 Ohm
I use a pack of four Philips RCC36,6/15.6 - 4C 65 (22mm/36mm).
the pack is cooled by a separate fan whenever the PA is switched
to >400W output. wire: prim 2mm, sec 1,5mm.
regards
