PO Box J,One Commercial Row, Wallkill, NY 12589-0288 Phone: (888) 324-7748 www.fair-rite.com Frequency Range: Suppression Applications for Broadband Frequencies 20-300 MHz (43 material) Application: Suppression Components Where Used: Board Component Part Type: Multi-Aperture cores 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. Minimum impedance values are specified for 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 AL value. The test frequency is 10 kHz at < 10 gauss. The test winding is five turns wound through both holes. -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 prototype evaluation. -Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade last digit 2 = burnished.
