28R1800-010

Overview

The 28R1800-010 is a solid ferrite core manufactured by Laird-Signal Integrity Products, designed for cable suppression applications. It features a rectangular geometry with an internal dimension of 35.05mm width by 1.52mm height and an external dimension of 45.72mm width by 12.70mm height. The component has a length of 27.94mm and utilizes Material 28 to achieve an impedance of 260 Ohms at 100MHz. It is classified as a free-hanging type suitable for direct installation on cables.

Feature Summary

• Solid construction utilizing Material 28 for effective high-frequency noise attenuation
• Rectangular profile engineered specifically for flat or ribbon cable geometries
• Free-hanging design allows for straightforward manual installation without additional fixtures

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering for data transmission lines in electronic assemblies
• Common mode noise reduction on power supply cables within equipment chassis

Procurement Notes

Verify the specific impedance requirement of 260 Ohms at 100MHz against your EMI mitigation targets. Confirm that the internal dimensions accommodate the target cable thickness. Ensure compliance with RoHS3 standards if required by your manufacturing process. Check for any specific packaging constraints associated with bulk orders.

Selection Notes

Select this component when dealing with flat cables requiring significant impedance in the VHF range. The Material 28 composition offers high permeability for broadband suppression. Compare the physical footprint against available space in the enclosure. Consider the thermal environment as ferrite properties can vary with temperature changes.
