2843000102

Overview

Fair-Rite 2843000102 is a multi-aperture ferrite core utilizing Material 43. It features two holes with an inner diameter of 1.8 mm and outer dimensions of 7.5 mm by 13.4 mm. The component provides an impedance of 122 ohms at 25 MHz and 205 ohms at 100 MHz. It operates within a temperature range of -55°C to +125°C and has a minimum inductance factor (AL) of 2200 nH.

Feature Summary

• Dual-hole geometry for accommodating multiple conductors
• Material 43 composition optimized for high-frequency noise suppression
• High permeability rating for effective common-mode choke applications

Applications

• EMI suppression on round cables
• Common-mode choke implementation
• Noise filtering in high-frequency circuits

Procurement Notes

Verify the specific material grade and impedance values against the manufacturer's current datasheet before integration. Confirm that the dual-aperture physical dimensions match the cable bundle requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this part when simultaneous suppression of multiple wires is required within a compact footprint. The Material 43 formulation is suitable for frequencies above 10 MHz. Verify that the 1.8 mm hole size accommodates the target conductor diameters without excessive air gap.

Part Context

This component belongs to Fair-Rite’s 28 series of multi-aperture cores. These cores are designed specifically for suppressing electromagnetic interference on bundles of wires or multiple conductors passing through the same aperture structure simultaneously.
