2643102402

Overview

The Fair-Rite 2643102402 is a round ferrite cable core utilizing Material 43. It features an inner diameter of 12.83 mm, an outer diameter of 25.91 mm, and a length of 21.34 mm. The component provides an impedance of 183 ohms at 100 MHz and has an inductance of 2.817 nH. Designed as a solid free-hanging bead, it serves as an EMI suppression device for cables passing through its aperture.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Material 43 composition optimized for high-frequency noise absorption
• Round geometry facilitates easy sliding onto existing wire harnesses

Applications

• Electromagnetic interference suppression on data cables
• Noise filtering on power supply lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific material grade and impedance specifications against your design requirements before ordering. Confirm that the inner diameter accommodates the target cable bundle without excessive force. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your manufacturing process.

Selection Notes

Select this component when a large aperture is required for multi-conductor cables. Material 43 is suitable for frequencies above 10 MHz. Compare physical dimensions against available space constraints. Consider the thermal characteristics of the ferrite material under expected operating conditions.
