28R0984-200

Overview

The 28R0984-200 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for EMI filtering applications. It exhibits an impedance of 170 Ohms at 100 MHz and operates within a temperature range of -40°C to +125°C. The component features a rectangular cross-section with an internal slot measuring 18.00 mm in width and 0.90 mm in height, accommodating flat ribbon cables. External dimensions are 25.00 mm in width and 7.70 mm in height.

Feature Summary

• Solid construction provides structural integrity for free-hanging installation on cable assemblies.
• Optimized magnetic properties deliver high attenuation performance at 100 MHz for noise suppression.
• Wide operating temperature range ensures reliable functionality in extreme thermal environments.

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Common mode noise reduction in data transmission lines
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific impedance tolerance and physical slot dimensions against your cable assembly requirements before procurement. Confirm that the solid core design aligns with your mechanical constraints for free-hanging applications. Ensure the operating temperature range meets your environmental specifications. Check for any RoHS compliance status updates as manufacturing practices may evolve.

Selection Notes

Select this component when a robust, non-split ferrite solution is required for flat ribbon cables. The 170 Ohm impedance at 100 MHz makes it suitable for broadband noise suppression. Consider the external dimensions to ensure adequate clearance in tight enclosures. Compare with split-core alternatives if retrofitting existing cables without disconnection is necessary.

Part Context

This part belongs to the 28R series of cable ferrites from Laird-Signal Integrity Products. The series offers various impedance values and core geometries tailored for different frequency ranges and cable types. The 28R0984-200 specifically targets applications requiring solid core stability and high-frequency attenuation capabilities.

Replacement Considerations

Direct substitutes include other solid ferrite cores with similar impedance characteristics and slot dimensions. Verify compatibility with the target cable width and height to ensure proper fit. Alternative models from the same manufacturer or third-party suppliers should match the 170 Ohm @ 100 MHz specification and temperature rating.

FAQ

What is the maximum current rating for the 28R0984-200?

The provided documentation does not specify a maximum current rating for this ferrite core. Current handling depends on the attached cable and application thermal conditions.

Is the 28R0984-200 compatible with round wires?

No, the 28R0984-200 is designed as a solid core with a wide, narrow slot specifically intended for flat ribbon cables. It is not suitable for round wires.
