Multi-Aperture Cores
Multi-aperture cores are used in balun (balance-unbalance) transformers and find wide application
as broadband transformers in communication and CATV circuits. They are also employed in auto
air bag circuits to guard against accidental activation.
• All multi-aperture cores are supplied burnished.
• For additional technical information on the use of these cores, see section “Use of Ferrites in Broadband Transformers”
• Multi-aperture cores are controlled for impedance limits only. They are tested for impedance with a single turn through two
• For impedance vs. frequency curves for these parts, see Figures 4-37.
• For any multi-aperture core requirement not listed in the catalog, please contact our customer service group for
