Multi-aperture cores are used in balun (balance-unbalance) transformers and find wide
applications as broadband transformers in communications and CATV circuits. They are also
employed in airbag designs to prevent accidental activation.

All multi-aperture cores are supplied burnished.
All listed impedance values are typical values. Minimum impedance values are specified for the + marked
Multi-aperture cores are measured for impedance on the 4193A Vector Impedance Analyzer. The cores are wound
with a single turn through both holes, with the shortest practical wire length.
The 61 and 67 material multi-hole beads are tested for A
Performance curves for all multi-hole cores can be found on the Fair-Rite Products CD-ROM.
For any multi-aperture core requirement not listed, please contact our customer service group for availability and pricing.
Our "Multi-Aperture Core Kit" (part number 0199000036) is available for proto type evaluation. See page 68.
Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade last digit 2 = burnished.
Multi-aperture cores in 73 and 43 materials are controlled for impedance only. The 61 NiZn material is controlled for
both impedance and A
frequencies. The minimum guaranteed impedance is the listed typical impedance less 20%.
test winding is five turns wound through both holes.
