Iron Powder Toroidal Cores For Power Conversion and Line Filter Applications

T 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=$\sqrt{\mathrm{\text{'}mH\text{'}\; /\text{'}A_L\text{'}}}$, (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 the Iron Powder core material
Color may vary by material and coating characteristics

Material 8/90 is the same as 8 and can be used on RF, Power Conversion and Line Filter applications.
Material 2 may also be used for all RF, Power Conversion and Line Filter applications.
Materials 28 and 30 are insignificantly different, just as materials 34 and 35 are to material 33.

Typical Part Number: (Type/Size (inches) - Material/Alternate HT)
Ex: T106-18  T = Toroidal,  1.06 = O.D. Dimension,  18 = Material Type or Mix
O.D. is divided by 100 to get measurement in inches
