Part Type Information
Bobbins are an economical and well-proven core design for many applications where relatively low but stable inductance
values are required.
-For higher frequency designs, use small bobbins in 43 material.
-For power applications, bobbins in 77 material are specified for AL and dc bias limits.
-Bobbins in Figures 2-5 can be supplied with a uniform coating of thermo-set plastic coating which can withstand a
minimum breakdown of 500Vrms. This coating will change the dimensions a maximum of 0.5mm (.020''). The last digit of
the thermo-set plastic coated part is an '8'.
-The listed dimensions are for assembled bobbins without thermo-set plastic.
-Bobbins are tested for AL value at 1kHz < 10 gauss.
-For any bobbin requirement not listed in the catalog, please contact our customer service group for availability and
pricing.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, last digit 8 = coated bobbin.

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
A ½ turn is defined as a single pass through a hole.
