28B2000-100

Overview

The 28B2000-100 is a cylindrical solid core ferrite suppressor manufactured by Laird-Signal Integrity Products. Designed for round cable applications, this component features an inner diameter of 1.000 inches (25.40mm) and an outer diameter of 2.000 inches (50.80mm). The unit has a length of 1.130 inches (28.70mm) and utilizes a free-hanging mounting type. It provides an impedance of 305 Ohms at 100MHz, serving as an effective EMI filter for broadband noise suppression on cables fitting within the specified bore dimensions.

Feature Summary

• Solid core construction designed specifically for suppressing electromagnetic interference on round cables
• Broadband filtering capability providing significant impedance across high-frequency ranges
• Free-hanging installation method allows for easy placement around existing cable assemblies

Applications

• Suppression of common mode noise on power cables
• EMI filtering for communication and data transmission lines
• Noise reduction in industrial equipment cabling

Procurement Notes

Verify that the target cable diameter falls within the 25.40mm inner dimension specification to ensure proper fit. Confirm that the application requires a solid core design rather than a split-core variant. Check datasheets for specific impedance curves relevant to your frequency range. Ensure compliance with RoHS3 standards if required by your manufacturing process.

Selection Notes

Select this component when dealing with large diameter cables requiring robust EMI suppression. The 25.40mm bore size accommodates substantial cable bundles or heavy-gauge wires. Consider the physical length of 28.70mm for available space constraints. This part is suitable for applications where split cores are impractical due to cable termination or connector presence.

Part Context

This component belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It is distinct from surface-mount beads like the HI2220 series or smaller through-hole components. The 28B2000-100 is part of a family of cylindrical cores differentiated primarily by their inner and outer diameters to match various cable sizes.
