7427251

Overview

The Würth Elektronik part number 7427251 is a flat ribbon cable ferrite core belonging to the WE-SFA series. It provides an impedance of 180 Ohms and accommodates up to 40 poles. The component features a solid construction designed for flat ribbon cables, with external dimensions measuring 52 mm in length and 2 mm in thickness.

Feature Summary

• Designed specifically for flat ribbon cables
• Solid core construction without opening mechanism
• Provides 180 Ohms impedance at test frequency

Applications

• EMI suppression on flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Noise reduction in multi-conductor flat cable assemblies

Procurement Notes

Verify the specific impedance value and pole capacity against the official datasheet before integration. Confirm that the solid design matches the assembly requirements, as this model does not feature an openable clamp mechanism. Ensure compatibility with the target flat ribbon cable width and thickness specifications.

Selection Notes

Select this component when dealing with fixed flat ribbon cables where an openable core is unsuitable. The 40-pole capacity supports high-density data lines. Consider the physical profile and mounting constraints associated with solid cores compared to snap-on alternatives.

Part Context

This part belongs to the WE-SFA series of flat cable ferrites from Würth Elektronik. It serves as a passive EMI suppression solution for multi-wire flat cables, distinct from round or openable ring cores found in other product families.

FAQ
