Bobbins - Fair-Rite Products Corp.

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 thermo-set plastic coating which can withstand a minimum breakdown of
500Vrms. This coating will change the dimensions a maximum of 0.5 mm (0.020"). 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.
