1.5 Inch Long x .25 inch Diameter Ferrite Rods. These are "Fair-Rite", Part Number is "4077266011".
I calculated the "AL" Value of these Rods to be 448 per 100 turns. So if you want to wind a Specific Inductance you can easily calculate the required number of turns. Using the Formula below will get you Very Close to the inductance Value you want.
EXAMPLE 1: If you want 50 uH, Divide the 50 uH by 448 and you will get 0.1116071. Now take the Square Root of this 0.1116071 and you get 0.3340764. Multiply this 0.3340764 times 100 and you get 33.4 Turns.
EXAMPLE 2: Assume you want 300 uH for a Pin Pointing coil for a PI Metal Detector. Divide the 300 uH by 448 and you will get 0.6696428. Now take the Square Root of this 0.6696428 and you get 0.818317. Multiply this 0.818317 times 100 and you get 81.8 Turns.
Excellent for "Pin-Pointer Metal Detector Coils" or "Stun Gun Transformers". Unit Cost is $0.60 USD, Plus the Shipping Cost.
