Multi- Aperture cores (2867006802)

Part Number: 2867006802

67 MULTI- APERTURE CORE

Explanation of Part Numbers:

– Digits 1 & 2 = Product Class

– Digits 3 & 4 = Material Grade

•– Last digit 2 = Burnished

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.

•Our “Multi- Aperture Core Kit” (part number 0199000036) is available for prototype evaluation.

For any multi- aperture requirement not listed here, feel free to contact our customer service group for availability and

pricing.

Multi- aperture cores in 73 and 43 materials are controlled for impedance only. The 61 NiZn material is controlled for both

impedance and A

the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.

•Multi- aperture cores in 73 and 43 material are measured for impedance on the 4193A Vector Impedance Analyzer. The 61 and

67 multi- aperture cores are tested on the 4291A 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 A

five turns wound through both holes.
