28B0250-700

Overview

The 28B0250-700 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an impedance of 135 Ohms at 100 MHz and utilizes Material 28 for EMI suppression. The component has a round design with an inner diameter of 0.125 inches (3.18 mm), an outer diameter of 0.250 inches (6.35 mm), and a length of 0.394 inches (10.00 mm).

Feature Summary

• Solid construction designed for free-hanging cable installation.
• Material 28 composition optimized for high-frequency noise attenuation.

Applications

• Signal integrity enhancement on data cables.
• EMI reduction in electronic assemblies.
• RFI suppression on external wiring.

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet to ensure compatibility with target cable diameters. Confirm that Material 28 meets the required frequency response characteristics for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. Ensure the target cable diameter fits within the 0.125-inch inner diameter specification. Consider the 135 Ohm impedance profile at 100 MHz for appropriate noise filtering requirements.

Part Context

This part belongs to the Laird-Signal Integrity Products cable ferrite series. It serves as a passive component for electromagnetic interference mitigation. The solid design distinguishes it from split-core alternatives, offering a fixed geometry for consistent performance on secured cabling.

Replacement Considerations

Direct substitutes include other solid ferrite cores with similar inner diameters and impedance profiles. Verify material composition and dimensional tolerances to maintain signal integrity standards.
