Ferrite Shielding Beads : Large Beads or Cylindrical Toroids

---

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=$\sqrt{\mathrm{\text{'}mH\text{'}\; /\text{'}A_L\text{'}}}$
O.D. is the outer diameter of the bead
I.D. is the inside diameter of the bead
HT is the height of the bead
Hole type is the number of holes in the ferrite beads. Some beads have multiple holes
CWS ByteMark Part Number is the part number to use to place purchase order. 1 inch = 25.4 mm
Color may vary by material and coating characteristics
