Product Overview
The 2873000102 Multi-Aperture Core is designed for suppression applications, balun (balance-unbalance) and other broadband transformers. It is also utilized in airbag designs to prevent accidental activation. All multi-aperture cores are supplied burnished. A Multi-Aperture Core Kit (part number 0199000036) is available for prototype evaluation. For custom requirements not listed, please contact customer service.

Material Notes: 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. Impedance measurements for 73 and 43 materials are performed on the E4990A Impedance Analyzer with a single turn to both holes, using the shortest practical wire length. Impedance measurements for 61 and 67 materials are performed on the E4991A / HP4291B Impedance Analyzer with a single turn to both holes, using the shortest practical wire length. 61 and 67 material multi-hole beads are tested for AL value at 10 kHz at < 10 gauss with a five-turn winding through both holes.
