Molypermalloy (MPP) Toroidal Cores

CM Series

A_L (nH/Square Turn or nH/N²) is the A_L value.
L is inductance in nH (nanohenries)
N is the number of turns of a wire
Required turns (N) = square root of (desired 'L' /'A_L'), √'L' /'A_L', or 1000 turns=

\sqrt{'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
Material is toroid material
Color may vary by material and coating characteristics
