T50-56 Torroid Equivalent diameter 1/2" inside 1/4"
This is a non standard material with a very high permeability of 125u AL value 56 flux density 7000
Alloy powder coated toroidal core outside diameter 1/2" inside diameter 1/4" height approx. 4 10ths
we cannot find an exact equivalent in the normal micrometal range so we have listed it as T50-56 guessing it sits in between the RFI end and the LF/HF sections of the radio toroid
Material is a more expensive mix of FE-NI-Mo alloy for good stability
