28B0625-000

Overview

The 28B0625-000 is a solid ferrite cable core manufactured by Laird-Signal Integrity Products. It provides an impedance of 163 Ohms at 100 MHz and utilizes material grade 28. The component features a circular design with free-hanging installation, suitable for EMI suppression on cables. Physical dimensions include an inner diameter of 7.87 mm (0.310 inches), an outer diameter of 15.88 mm (0.625 inches), and a length of 14.27 mm (0.562 inches).

Feature Summary

• Solid construction designed for direct cable mounting without split halves.
• Utilizes Material Grade 28 composition for specific frequency attenuation characteristics.
• Free-hanging installation style allows for flexible placement on wires.

Applications

• Electromagnetic interference suppression on power cables
• Noise filtering on signal wiring harnesses
• Common mode noise reduction in electronic assemblies

Procurement Notes

Verify the exact impedance value of 163 Ohms at 100 MHz against your specific noise spectrum requirements. Confirm that the 7.87 mm inner diameter accommodates the target cable insulation thickness. Ensure the solid core design is compatible with your assembly process, as it cannot be opened like split cores. Check RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a non-split, solid ferrite core is required for permanent cable treatment. The choice depends on matching the cable diameter to the 7.87 mm inner bore. Consider the Material 28 specification for its performance profile in the targeted frequency range compared to other available grades. Evaluate the physical size constraints relative to the available space around the cable.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. These components are distinct from surface-mount beads or split cores, offering a robust solution for wire-level EMI control. The series provides various impedance levels and material compositions to address different noise frequencies and cable sizes within industrial and commercial electronics.
