Bobbins (9677001015)

Part Number: 9677001015

77 BOBBIN GROUND

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 A_L 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 pricing.
