28B0870-100

Overview

The Laird-Signal Integrity Products 28B0870-100 is a solid, free-hanging ferrite cable core designed for electromagnetic interference suppression. It features a cylindrical geometry with an inner diameter of 13.72 mm (0.540 inches) and an outer diameter of 22.10 mm (0.870 inches). The component has a length of 12.70 mm (0.500 inches) and utilizes material grade 28. It provides an impedance of 122 Ohms at a test frequency of 100 MHz.

Feature Summary

• Solid construction with free-hanging mounting capability
• Cylindrical round core design for cable integration
• Utilizes material grade 28 for signal integrity

Applications

• Electromagnetic interference filtering on cables
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 85 Ohms and 122 Ohms for similar part numbers. Confirm physical dimensions match the required cable diameter of 13.72 mm. Ensure compliance with RoHS3 standards if required by your assembly specifications.

Selection Notes

Select this component when a large bore size is necessary to accommodate thick cables or bundles. The 122 Ohm impedance at 100 MHz suits specific noise frequencies. Compare against the 28B0870-000 variant which shares identical dimensions but may differ in impedance characteristics.

Part Context

This part belongs to the 28B series of solid ferrite cores from Laird-Signal Integrity Products. These components are distinct from snap-on types due to their solid construction, requiring cables to be threaded through during assembly. They serve as passive filters to attenuate high-frequency noise.

Replacement Considerations

The 28B0870-000 is a dimensional substitute within the same series. Verify impedance compatibility before substitution.
