28B1387-000

Overview

The 28B1387-000 is a solid round ferrite core manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference suppression. It features an impedance of 115 Ohms at 100 MHz and utilizes Material 28. The component has an inner diameter of 22.40 mm (0.882 inches) and an outer diameter of 35.23 mm (1.387 inches). It is classified as a cable ferrite with a free-hanging installation type.

Feature Summary

• Solid construction for durable EMI suppression
• Material 28 composition for specific frequency attenuation
• Free-hanging design for easy cable integration

Applications

• Electromagnetic interference suppression in electronic systems
• Cable filtering for signal integrity enhancement

Procurement Notes

Verify the exact physical dimensions against your cable specifications before procurement. Confirm that Material 28 aligns with your target noise frequency spectrum requirements. Ensure the free-hanging mounting style fits your mechanical assembly constraints. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high current capacity or large cable diameters are required, given its substantial inner diameter. Consider Material 28 characteristics for the specific frequency range of interference you need to attenuate. Evaluate the physical size constraints of your enclosure to accommodate the larger outer dimensions compared to standard chip beads.
