FC25B2480

Overview

The FC25B2480 is a flat ribbon ferrite clamp-on core manufactured by LeaderTech Inc. Designed for suppressing electromagnetic interference on flat cables, this component features an adhesive mounting type for secure attachment. The core has an internal length of 52 mm and an internal height of 1.5 mm to accommodate specific cable profiles. External dimensions include a width of 80.8 mm and a height of 20.3 mm. It offers an impedance of 790 Ohms at 700 MHz. The product is supplied in bulk packaging and complies with RoHS standards.

Feature Summary

• Provides high impedance (790 Ohms) for effective EMI suppression on flat ribbon cables
• Features integrated adhesive backing for direct surface mounting without additional hardware
• Engineered with precise internal dimensions to fit specific flat cable geometries

Applications

• Suppression of electromagnetic interference in embedded electronics assemblies
• Noise reduction on flat ribbon cables within computer peripherals
• EMI mitigation in industrial control systems utilizing flat cable interconnects

Procurement Notes

Verify the exact internal dimensions against your cable specifications before ordering, as the 1.5 mm internal height is critical for proper fit. Confirm that the adhesive mounting method aligns with your assembly process requirements. Ensure compliance with RoHS directives if operating in regulated markets. Check current availability status as supply levels may vary.

Selection Notes

Select this model when dealing with flat ribbon cables requiring significant noise attenuation at high frequencies. The 790 Ohm impedance rating makes it suitable for broadband suppression applications. Consider the adhesive installation feature if space constraints prevent the use of clamps or straps. Compare internal dimensions with alternative models like FC20B2480 if different cable thicknesses are involved.

Part Context

This component belongs to the LeaderTech Cable Ferrites category, specifically under Clamp On Cores. It is part of a broader range of passive EMI/RFI suppression components designed to protect sensitive electronic circuits from external noise sources. The series includes various shapes and sizes tailored for different cable types and mounting needs.

Replacement Considerations

FC20B2480 shares identical external dimensions and impedance characteristics but differs in internal length. Verify internal cable clearance compatibility before substitution. No other direct substitutes are confirmed in public documentation.
