28R0669-000

Overview

The Laird-Signal Integrity Products 28R0669-000 is a solid free-hanging ferrite cable core designed for electromagnetic interference suppression. Constructed from Material 28, it provides an impedance of 110 Ohms at 100 MHz. The component features an internal slot measuring 13 mm in length and 0.75 mm in height, with external dimensions of 17 mm x 12 mm x 3.5 mm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid free-hanging design for easy installation on cables
• Optimized nickel-zinc ferrite material for high-frequency suppression
• Fixed impedance characteristic at 100 MHz

Applications

• Suppression of common mode noise on flat ribbon cables
• EMI filtering in signal lines operating near 100 MHz
• Noise reduction in data transmission interfaces

Procurement Notes

Verify the specific impedance value and frequency rating against your system requirements before procurement. Confirm that the internal slot dimensions accommodate the target cable thickness. Ensure the operating temperature range meets environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a non-snap-on ferrite solution is preferred for flat ribbon cables. The Material 28 composition targets the 10 MHz to 300 MHz range. Consider the physical size constraints of the assembly space. Evaluate if the fixed 110 Ohm impedance aligns with the noise spectrum of the application.

Part Context

This part belongs to the 28R series of ferrite cable cores from Laird-Signal Integrity Products. These components utilize proprietary nickel-zinc formulations tailored for specific frequency bands. The 28R series is distinct from snap-on or split-core variants, offering a permanent solid structure for consistent performance.
