2643164151

Overview

The Fair-Rite Products Corp. part number 2643164151 is a split round cable ferrite core designed for electromagnetic interference (EMI) suppression. It utilizes Material 43, which provides high impedance characteristics in the frequency range of 25 MHz to 300 MHz. The component features a split design that allows for installation over existing cables without disconnecting them. Key physical dimensions include an internal diameter of 10.15 mm and an external diameter of 18.7 mm. The core has a height of 50.8 mm. At a test frequency of 100 MHz, the impedance is specified as 185 ohms.

Feature Summary

• Split construction enables snap-on installation over pre-existing wiring harnesses
• Material 43 composition provides effective attenuation across the 25 MHz to 300 MHz spectrum
• Round geometry accommodates cylindrical cables with an internal diameter of 10.15 mm

Applications

• Electromagnetic interference suppression on power and signal cables
• Noise reduction in portable electronic devices
• Filtering in battery charger assemblies
• Voltage regulation circuit protection

Procurement Notes

Verify the specific ordering suffix to confirm the exact material grade and dimensional tolerances match the design requirements. Ensure the split mechanism integrity is suitable for the intended cable diameter. Confirm RoHS compliance status if required by the end-product regulations. Cross-reference the impedance value at 100 MHz against the system's noise frequency profile to ensure adequate suppression performance.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The split design is preferred over solid cores for retrofitting or applications where cables cannot be disconnected. Material 43 is appropriate for higher frequency noise environments up to 300 MHz. Consider the internal diameter constraint of 10.15 mm to ensure compatibility with the target cable bundle size.
