28B0562-300

Overview

The 28B0562-300 is a solid, free-hanging cylindrical ferrite core manufactured by Laird-Signal Integrity Products. It is designed for broadband EMI suppression on round cables and wiring harnesses. The component features an inner diameter of 0.250 inches (6.35mm), an outer diameter of 0.562 inches (14.27mm), and a length of 1.115 inches (28.32mm). It provides an impedance of 270 Ohms at 100MHz. The unit is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

• Solid construction for effective broadband electromagnetic interference suppression
• Free-hanging design allows easy installation onto existing cable assemblies
• Cylindrical geometry optimized for round cables and wiring harnesses

Applications

• Suppression of noise on round power cables
• EMI filtering for wiring harnesses in electronic equipment
• Broadband noise reduction in signal transmission lines

Procurement Notes

Verify the specific impedance value required for your application against the datasheet, as some sources may list variations. Confirm that the inner diameter of 0.250 inches accommodates the target cable bundle without excessive force. Ensure compliance with RoHS3 regulations if applicable to your manufacturing region. Check for any specific handling requirements during assembly.

Selection Notes

Select this component when a non-snap-on, solid ferrite solution is preferred for permanent or semi-permanent cable treatment. The 270 Ohm impedance at 100MHz suits high-frequency noise attenuation. Consider the physical dimensions to ensure adequate clearance around the cable. This part is suitable for applications where snap-fit cores are not feasible due to cable shape or size constraints.
