Ferrite Toroidal Cores

A generic image
F-series


AL (nH/Square Turn or nH/N2) is the AL value.
L is inductance in nH (nanohenries)
N is the number of turns of a wire
Required turns (N) = square root of (desired 'L' /'AL'), √'L' /'AL', or 1000 turns='mH' /'AL', (square rooted)
CWS ByteMark Part Number is the part number to use to place purchase order. 1 inch = 25.4 mm
O.D. is the outer diameter of the toroid core
I.D. is the inside diameter of the toroid core
HT is the height of the toroid core
Color may vary by material and coating characteristics
Parts are RoHS compliant
