RA28B1265

Overview

The RA28B1265 is a hinged flat cable ferrite core manufactured by Leader Tech Inc. It features a snap-on design for easy installation on ribbon cables. The component exhibits an impedance of 148 Ohms at a test frequency of 100 MHz. Its internal dimensions are 26.6 mm in width and 0.97 mm in height, while the outer dimensions measure 39.6 mm in length, 39.6 mm in width, and 10.2 mm in height. The material composition is designated as Type 28.

Feature Summary

• Hinged snap-on design allows for quick attachment to existing cables without disconnection
• Flat profile accommodates ribbon and flat cabling configurations
• Solid ferrite construction provides effective electromagnetic interference suppression

Applications

• Suppression of common mode noise on flat ribbon cables
• EMI filtering in computer peripheral connections
• Noise reduction in internal bus architectures

Procurement Notes

Verify the specific impedance rating and physical dimensions against your cable assembly requirements before procurement. Confirm that the hinged mechanism remains secure during operation. Ensure compatibility with the target cable thickness to maintain effective magnetic coupling. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a non-invasive solution for flat cable noise suppression is required. The hinged design eliminates the need to thread cables through solid cores. Consider the 148 Ohm impedance value relative to the noise frequencies present in your application. Ensure the internal opening size matches the flat cable dimensions for optimal performance.

Part Context

This part belongs to the Leader Tech Inc. family of cable ferrites. These components are designed for electromagnetic interference suppression in electronic assemblies. The RA28B1265 specifically targets flat cabling applications where space constraints or convenience favor a snap-on mechanism over traditional split-core designs.
