28B0590-000

Overview

The Laird-Signal Integrity Products 28B0590-000 is a solid, free-hanging ferrite core designed for cable noise suppression. It features a circular design with an inner diameter of 6.99mm (0.275 inches), an outer diameter of 14.99mm (0.591 inches), and a length of 27.94mm (1.100 inches). The component provides a nominal impedance of 300 Ohms at 100 MHz, with a minimum impedance of 170 Ohms measured at 300 MHz. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C. The part is RoHS compliant and classified under HTSUS code 8547.10.8000.

Feature Summary

• Solid round construction for secure cable clamping
• High impedance performance for EMI/RFI suppression
• Free-hanging mounting style for flexible installation

Applications

• Suppression of high-frequency noise on cables and wiring
• Signal integrity enhancement in electronic assemblies
• EMI filtering for power and data lines

Procurement Notes

Verify the specific impedance requirements against the datasheet curves, as values vary by frequency. Confirm that the cable diameter fits within the 6.99mm inner dimension. Check for RoHS3 compliance if required by your manufacturing standards. Ensure the operating temperature range meets your environmental specifications. Validate the package type matches your assembly process.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable attachment. Consider the 300 Ohm impedance at 100 MHz for effective high-frequency noise attenuation. Evaluate the physical dimensions to ensure compatibility with the target cable size and available space. Compare alternative materials if different frequency characteristics are needed.
