I bought these hoping to avoid handwinding 46 turns of #30 on FT50-61 cores. The cores I received measured ((Tenma Auto LCR) about .04 ohms and 92 to 93 uhy at 1khz. The Q was 39 at 10 khz , maximum "Q" was at 38 khz typically, but Q is below 25 at all frequencies above100 khz and no parallel resonances. Likely a Mn-Zn ferrite. I needed a Q of more than 150 at 1.2 mhz. These would be useless on most designs that operate above 30 khz, unless you need RF/EMI filtering. If these used a Ni-Zn ferrite, like type 61 ferrite or even type 43, the cores would be a much better product and still profitable. Nice looking winding job.
