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 a small bobbin (Figure 1) in 43 material.
• For power applications, bobbins in 77 material are specified for A
• Bobbins in Figures 2-5 can be supplied with a uniform coating of thermo-set plastic coating which can withstand a minimum
• The listed dimensions are for assembled bobbins without thermo-set plastic.
• Bobbins are tested for AL value at 1kHz < 10 gauss.
• Bobbins 9677142089 through 9677242489 can also be purchased as tack bobbin cores. (See page 103).
• For any bobbin requirement not listed in the catalog, please contact our customer service group for availability and pricing,

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". Bobbins in Figure 5 can be supplied with notches at one end only. This changes the last digit of the
part number to a "7". Bobbins of this type can also be provided with a themo-set plastic coating. The last digit becomes a "6".
