28R1518-000

Overview

The 28R1518-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for EMI suppression on flat or ribbon cable assemblies. It features a rectangular geometry with an internal slot measuring 26.80mm x 1.91mm and external dimensions of 47.6mm length, 38.4mm width, and 12.1mm height. The component exhibits an impedance of 235 ohms at 100 MHz and utilizes material grade 28. It operates within a temperature range of -40°C to +125°C and is supplied in bulk packaging.

Feature Summary

• Solid free-hanging design allows for simple installation on existing cable assemblies without complex mounting hardware
• Rectangular shape with internal slot specifically engineered for flat or ribbon type cables
• Passive operation requires no external power source for effective common mode EMI reduction

Applications

• EMI suppression on flat or ribbon cable assemblies
• Common mode noise reduction in communication signal processing boards
• Noise filtering in high-power motor control cabinets

Procurement Notes

Verify the specific impedance value of 235 ohms at 100 MHz against your system requirements before procurement. Confirm that the internal slot dimensions of 26.80mm x 1.91mm are compatible with the target cable thickness. Ensure the operating temperature range of -40°C to +125°C meets environmental conditions. Check for RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when dealing with flat or ribbon cables rather than round wires due to its rectangular slot design. The material grade 28 provides specific frequency characteristics suitable for general EMI suppression. Consider the physical size constraints as the external dimensions are significantly larger than standard through-hole ferrites. Evaluate the need for free-hanging installation versus clamped alternatives based on assembly space.

Part Context

This part belongs to the 28R series of rectangular EMI suppression ferrite cores from Laird-Signal Integrity Products. The series focuses on cost-effective solutions for reducing common mode interference in electronic interconnects. These components are part of Laird's Performance Materials division, which specializes in electromagnetic interference shielding and signal integrity products for various industrial and commercial sectors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with alternative rectangular ferrite cores by matching the internal slot dimensions and impedance characteristics at the target frequency.
