28A2738-0A2

Overview

The Laird-Signal Integrity Products 28A2738-0A2 is a split snap-on ferrite cable core designed for electromagnetic interference suppression. It utilizes material grade 28 to provide an impedance of 233 Ohms at 100 MHz. The component features a circular design with a hinged installation type, allowing it to be clamped onto cables without disconnection. Key dimensions include an inner diameter of 9.00 mm and outer dimensions of 18.00 mm width by 19.70 mm height.

Feature Summary

• Hinged snap-on design enables easy installation on existing cables
• Material grade 28 provides effective noise suppression characteristics
• Circular form factor accommodates standard cable diameters

Applications

• Electromagnetic compatibility improvement for wiring harnesses
• Noise suppression on signal and power cables
• Cable filtering in electronic assemblies

Procurement Notes

Verify the specific impedance value and physical dimensions against the official manufacturer datasheet before integration. Confirm that the material grade matches the intended frequency response requirements. Ensure the inner diameter is sufficient for the target cable bundle size to guarantee proper fit and performance.

Selection Notes

Select this component when a non-invasive solution for cable noise reduction is required. The snap-on mechanism simplifies assembly compared to solid cores. Consider the 233 Ohm impedance rating at 100 MHz to ensure adequate attenuation for the specific interference frequencies present in the application environment.

Part Context

This part belongs to the 28A series of ferrite cores from Laird-Signal Integrity Products. The series offers various sizes and impedances tailored for different cable diameters and noise profiles. The 28A2738-0A2 specifically targets applications requiring moderate impedance with convenient clip-on installation for rapid prototyping or maintenance scenarios.

Replacement Considerations

Check for direct substitutes within the same 28A series offering similar inner diameters and impedance values. Verify that any alternative maintains the snap-on design if ease of installation is critical. Ensure material composition remains compatible with the operating temperature range.
