R 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=$\sqrt{\mathrm{\text{'}mH\text{'} /\text{'}AL\text{'}}}$, (square rooted)
CWS ByteMark Part Number is the part number to use to place purchase order. 1 inch = 25.4 mm
O.D./ W is the outer diameter or width of the Ferrite
