28R1025-000

Overview

The 28R1025-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 97 Ohms at a test frequency of 100 MHz. The component features an inner diameter with dimensions of 0.843 inches in width and 0.030 inches in height, equivalent to 21.40 mm by 0.75 mm. This design allows for direct installation over cables without requiring clamping mechanisms or split halves.

Feature Summary

• Solid construction designed for free-hanging installation directly onto cables
• Provides specific electromagnetic interference suppression characteristics at high frequencies

Applications

• Suppression of electromagnetic interference on ribbon cables
• Noise filtering on signal lines within electronic assemblies
• EMI mitigation on power cables in industrial equipment

Procurement Notes

Verify the exact inner diameter requirements against the cable bundle thickness before procurement. Confirm that the solid core design accommodates the specific cable geometry, as it cannot be opened like split cores. Ensure the application environment does not require magnetic shielding beyond the core's inherent properties.

Selection Notes

Select this component when a non-intrusive, solid ferrite solution is required for cables that fit within the specified inner diameter. The 97 Ohm impedance at 100 MHz targets specific noise frequencies. Consider physical constraints regarding the fixed nature of the core compared to split alternatives.

Part Context

This part belongs to the 28R series of ferrite cable cores from Laird-Signal Integrity Products. These components are engineered for signal integrity and electromagnetic compatibility in various electronic systems. The series offers different impedance values and physical dimensions to suit diverse cable types and noise profiles.

Replacement Considerations

Direct substitutes must match the 97 Ohm impedance at 100 MHz and the 0.843-inch inner diameter. Verify material composition and temperature ratings if operating conditions differ from standard specifications.
