2661666611

Overview

Fair-Rite Products Corp. part number 2661666611 is a solid, free-hanging ferrite cable core constructed from 61 material composition. It provides an impedance of 380 ohms at a test frequency of 100 MHz. The component features a circular cross-section with an inner diameter of 0.394 inches (10.01 mm), an outer diameter of approximately 0.55 inches, and a length of 0.75 inches (19.05 mm). Designed for through-hole installation on wires and cables, it operates within a temperature range of -55°C to +125°C. The unit is supplied in bulk packaging and complies with RoHS3 standards.

Feature Summary

• Utilizes 61 material composition for effective high-frequency noise suppression
• Solid cylindrical design ensures stable mechanical integrity during installation
• Free-hanging configuration allows flexible placement on various wire gauges

Applications

• EMI suppression on data communication cables
• High-frequency noise filtering on power supply lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific impedance tolerance and DC current rating requirements against the official Fair-Rite datasheet before ordering. Confirm that the inner diameter accommodates the target cable insulation thickness without excessive friction or looseness. Ensure compliance with project-specific environmental regulations such as RoHS3 and REACH status. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and lead times.

Selection Notes

Select this component when targeting noise attenuation around 100 MHz using 61 material properties. The 10.01 mm inner diameter suits medium-gauge cables requiring substantial magnetic path volume. Consider the solid construction for applications demanding robust physical handling compared to hinged alternatives. Evaluate thermal performance limits relative to ambient operating conditions and self-heating effects under load.

Part Context

This ferrite core belongs to Fair-Rite's standard line of solid cable cores, distinct from snap-it or wound bead variants. It complements other components in the 266 series designed for general-purpose EMI mitigation. The 61 material offers a balance of permeability and resistivity suitable for broadband interference reduction across digital and analog signal paths.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Fair-Rite technical support or equivalent distributors for direct replacements based on impedance curves and dimensional constraints.
