• Part number is for a single core.

• These U cores have the same minimum cross-sectional area as the listed effective cross-sectional area.

• AL value is measured at 1kHz, < 10 gauss.

• For any U core requirement not listed in the catalog, please contact our customer service group for availability and pricing.
