Multi- Aperture cores (2867002702) Part Number: 2867002702 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.

The 61 NiZn material is controlled for both impedance and A value. The high frequency 67 material is controlled for A value. Minimum impedance values are specified for L L the + marked frequencies. The minimum impedance is listed on our catalog drawing. Catalog Drawing Multi- aperture cores in 73 and 43 material are measured for impedance on the E4990A Impedance Analyzer. The 61 and 67 multi- aperture cores are tested on the E4991A / HP4291B 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 value. The test frequency is 10 kHz at < 10 gauss. The test winding is L five turns wound through both holes.CSV Download Fair- Rite Products Corp.
