Toroid FT82-43
Toroid core weight = 6.65 grams
OD = 21mm 0.82"
ID = 13.2mm 0.3"
Height = 6.35mm 0.25"
Material: ferrite, type 43.
FT82-43 toroids are used to make EFHW transformers in some antenna designs. But if the design you are following does not specifically require FT82-43, you might like to consider a 2643625002 or 2643251002 toroid instead.
This size is a bit on the small side for making a balun by winding coax around it, we suggest using FT114-43 or larger for that.
We also sell larger toroids of the same material and of a similar shape here: FT114-43 / FT140-43 / FT240-43
Toroid cores are brittle so avoid banging them against hard surfaces.
