28B0570-000

Overview

The 28B0570-000 is a solid, free-hanging ferrite cable core manufactured by Laird-Signal Integrity Products. It utilizes material grade 28 to provide electromagnetic interference suppression for cables. The component features an inner diameter of 0.335 inches (8.51 mm) and an outer diameter of 0.570 inches (14.48 mm). Its physical length is 0.217 inches (5.51 mm). The core exhibits an impedance of 82 Ohms at a test frequency of 100 MHz.

Feature Summary

• Solid cylindrical construction designed for free-hanging installation on cables
• Utilizes material grade 28 for effective high-frequency noise attenuation
• Provides specific impedance characteristics optimized for signal integrity applications

Applications

• Cable assembly EMI filtering
• Signal line noise suppression
• Power cable interference reduction

Procurement Notes

Verify the exact impedance value and material grade against the official manufacturer datasheet before procurement. Confirm that the inner diameter accommodates the target cable bundle size without excessive force or looseness. Ensure the application environment does not exceed the thermal limits associated with the ferrite material composition.

Selection Notes

Select this component when a non-snap-on, solid ferrite core is required for permanent cable treatment. The 8.51 mm inner diameter suits medium-gauge cables. Consider the 82 Ohm impedance profile at 100 MHz to ensure compatibility with the targeted noise frequency spectrum. Evaluate mechanical stability requirements as this type relies on friction fit rather than locking mechanisms.

Part Context

This part belongs to the 28B series of round cable cores from Laird-Signal Integrity Products. These components are distinct from snap-on cores due to their solid, one-piece design. The series offers various dimensions and impedance values to match different cable diameters and frequency requirements in electronic systems.

Replacement Considerations

Direct substitutes must match the 8.51 mm inner diameter, 14.48 mm outer diameter, and 5.51 mm length. Verify that alternative materials provide equivalent 82 Ohm impedance at 100 MHz to maintain circuit performance.
