Part Type Information
Multi-aperture cores are used in suppression applications and in balun (balance-unbalance) and other broadband transformers. They
are also employed in airbag designs to prevent accidental activation.
-All multi-aperture cores are supplied burnished.
-Multi-aperture cores in 73 and 43 materials are controlled for impedance only. The 61 NiZn material is controlled for both impedance
and AL value. The high frequency 67 material is controlled for AL value. All listed impedance values are typical values. Minimum
impedance values are specified for the + marked frequencies. The minimum guaranteed impedance is the listed typical impedance less 20%.
-Multi-aperture cores in 73 and 43 material are measured for impedance on the 4193A Vector Impedance Analyzer. The 61 multi-aperture
cores are tested on the 4191A Impedance Analyzer. All impedance measurements are performed with a single turn to both holes, using the
shortest practical wire length.
-The 61 and 67 material multi-hole beads are tested for AL value. The test frequency is 10 kHz at < 10 gauss. The test winding is
five turns wound through both holes.
-Preferred multi-aperture cores are the suggested choice for new designs. Samples are readily available and orders have typically
shorter lead times than other multi-aperture cores. For any multi-aperture requirement not listed here, feel free to contact our
customer service group for availability and pricing.
-Our 'Multi-Aperture Core Kit' (part number 0199000036) is available for proto type evaluation.
