28B1020-10G

Overview

The Laird-Signal Integrity Products 28B1020-10G is a solid round cable ferrite core designed for electromagnetic interference suppression. It utilizes Material 28 to provide an impedance of 276 Ohms at 100 MHz. The component features a free-hanging installation type with an inner diameter of 0.502 inches (12.75 mm), an outer diameter of 1.023 inches (25.99 mm), and a solid construction.

Feature Summary

• Solid round design for uniform magnetic flux distribution
• Material 28 composition optimized for high-frequency noise attenuation
• Free-hanging mounting configuration for flexible cable integration

Applications

• High-speed data cable EMI filtering
• Power line noise suppression in industrial equipment
• Signal integrity enhancement for communication interfaces

Procurement Notes

Verify the specific suffix '10G' against manufacturer documentation to confirm exact dimensional tolerances and material batch specifications. Ensure compatibility with existing cable diameters before procurement, as inner dimensions are critical for fitment. Cross-reference RoHS status with current regulatory requirements for the target market.

Selection Notes

Select this component when high impedance at 100 MHz is required for cables up to 12.75 mm in diameter. The solid construction offers mechanical stability compared to split cores. Consider the physical size constraints of the assembly space, as the outer diameter exceeds 25 mm. Material 28 characteristics should align with the specific frequency spectrum of the noise being mitigated.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. The series provides various sizes and materials to address different cable diameters and frequency ranges. The 28B1020-10G specifically addresses larger cable applications requiring robust noise suppression capabilities in a non-split form factor.

Replacement Considerations

The 28B1020-100 is a direct substitute with nearly identical dimensions (Inner: 12.83mm vs 12.75mm) and impedance characteristics. Verify that the slight difference in inner diameter does not affect cable fitment in the specific application.
