Bobbins (9677182208)
Part Number: 9677182208
77 BOBBIN 3PC. ASSEMBLY COATED
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
– Last digit 8 = Coated Bobbin
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”.
For any bobbin requirement not listed in the catalog, please contact our customer service group for availability and
