28B0250-100

Overview

The 28B0250-100 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It belongs to the 28B series and utilizes Material 28 for electromagnetic interference suppression. The component provides an impedance of 182 ohms at a test frequency of 100 MHz. It features an inner diameter of 3.18 mm (0.125 inches) and an outer diameter of 6.35 mm (0.250 inches). The physical length is 15.88 mm (0.625 inches). The part is currently in active production status.

Feature Summary

• Solid construction design for stable magnetic properties
• Free-hanging configuration allows easy installation on cables
• Material 28 composition optimized for high-frequency noise attenuation

Applications

• Suppression of common mode noise on signal cables
• EMI filtering for power supply lines
• Noise reduction in high-speed data transmission interfaces

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the cable diameter falls within the specified inner dimension range of 3.18 mm to ensure proper fit. Check for any RoHS compliance updates or environmental declarations required by your project specifications. Ensure the supplier provides traceable documentation matching the manufacturer's part number.

Selection Notes

Select this component when a solid ferrite core with Material 28 characteristics is required for frequencies around 100 MHz. The 182 ohm impedance value suits applications needing moderate attenuation without excessive signal loss. Consider the 6.35 mm outer diameter for spatial constraints. Compare against other 28B series variants if different impedance levels or dimensions are needed for specific cable sizes.

Part Context

This part is part of the 28B series of cable ferrites from Laird-Signal Integrity Products. The series offers various impedance values and dimensions using Material 28. Unlike chip beads, these cores are designed for wrapping around existing cables rather than surface mount integration. They serve as passive components for enhancing signal integrity in electronic assemblies.

Replacement Considerations

Direct substitutes include other 28B series cores with similar impedance and dimensions, such as those with Material 28 composition. Verify compatibility based on inner diameter and impedance at 100 MHz. Generic ferrite cores may not match the specific material properties unless explicitly rated for equivalent performance.
