2843001502

Overview

Fair-Rite 2843001502 is a multi-aperture ferrite core utilizing Material 43. It features seven apertures with an inner diameter of 0.150 inches (3.80 mm) and an outer diameter of 0.295 inches (7.50 mm). The component has a length of 0.525 inches (13.34 mm) and weighs 1.700 grams. Impedance is specified as 59 ohms at 25 MHz and 106 ohms at 100 MHz. Multi-aperture cores in Material 43 are controlled for impedance only.

Feature Summary

• Multi-aperture design providing seven distinct holes for cable passage
• Material 43 composition optimized for high-frequency noise suppression
• Solid free-hanging construction suitable for direct wire insertion

Applications

• Baluns
• Broadband transformers
• Airbag systems

Procurement Notes

Verify the specific impedance requirements against the official datasheet, as Material 43 multi-aperture cores are controlled for impedance only. Confirm that the seven-aperture configuration aligns with the intended cable routing density. Ensure the physical dimensions match the available space constraints within the assembly.

Selection Notes

Select this component when multiple conductors require simultaneous EMI suppression in a compact volume. Material 43 offers effective performance for broadband applications. The solid core design simplifies installation compared to split-core alternatives. Verify that the operating frequency range matches the target noise spectrum.
