Hello,

i have some ferite core (like EER or ETD) to get data sheet for that parameter.

a  = 40 mm
b  = 13 mm
h1 = 23.15 mm
h2 = 16.16 mm
d2 = 30.25 mm
d3 = 13 mm

thanks

without knowing what material it's made of or who manufactured it, there's really no way to tell what it is.  are there any markings on the cores at all?
