SA25B2480

Overview

The SA25B2480 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed for flat ribbon cables. It features an internal dimension of 52.00 mm width by 1.50 mm height and an external dimension of 65.3 mm width by 16.6 mm height. The component provides an impedance of 790 Ohms at 700 MHz and utilizes material grade 25. It is classified as a free-hanging type with a snap-on hinge design.

Feature Summary

• Hinged snap-on design allows for easy installation and removal around existing cable assemblies without disconnecting the signal path.
• Engineered specifically for flat ribbon cables, accommodating precise internal dimensions to ensure secure fitment.
• Provides high impedance characteristics at 700 MHz to effectively suppress electromagnetic interference on data lines.

Applications

• Suppression of common mode noise in parallel data bus connections
• EMI mitigation for flat ribbon cables in computer peripheral interfaces
• Signal integrity enhancement in high-speed digital transmission lines

Procurement Notes

Verify the specific adhesive configuration when comparing with similar part numbers, as suffixes may indicate different mounting methods such as adhesive-backed versus standard free-hanging versions. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component based on the required internal cable width and height to ensure proper mechanical fit. Evaluate the impedance requirement at the target frequency of operation to confirm adequate noise suppression performance for the specific application environment.

Part Context

This component belongs to the Leader Tech Inc. ferrite clamp-on core series, which offers various materials and geometries for EMI suppression. The SA25B2480 variant is optimized for flat cable applications, distinguishing it from round cable cores within the broader product portfolio.

Replacement Considerations

FD25B2480 is identified as a parameter-equivalent substitute option available from the same manufacturer.
