7427212

Overview

The Würth Elektronik 7427212 is a flat ferrite core designed for filtering ribbon cables and suppressing common-mode interferences. Constructed from 4 W 620 material, it features an internal length of 28 mm, an external width of 33.5 mm, and an external height of 6.5 mm. The component provides an impedance of 60 ohms and accommodates up to 21 wires within its inner dimensions of 28 x 1.3 mm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Designed specifically for easy filtering of ribbon cables
• Effective suppression of common-mode interferences
• Accommodates up to 21 wires within the core aperture

Applications

• Ribbon cable filtering
• Common-mode interference suppression
• Data bus protection

Procurement Notes

Verify the specific material grade (4 W 620) and dimensional tolerances against the official datasheet before integration. Confirm that the inner aperture size (28 x 1.3 mm) matches the target ribbon cable specifications. Ensure the operating temperature range (-40°C to +125°C) aligns with the environmental requirements of the final assembly.

Selection Notes

Select this component when filtering multi-conductor ribbon cables is required. The 4 W 620 material offers high permeability for effective noise suppression. Consider the physical constraints of the 28 x 1.3 mm inner dimension to ensure compatibility with the cable bundle. Evaluate the 60-ohm impedance characteristic against the frequency spectrum of the noise to be attenuated.

Part Context

This part belongs to the WE-FLAT series of solid ferrite cores manufactured by Würth Elektronik. These components are engineered for compact EMC solutions where space is limited. The flat geometry allows for efficient wrapping around flat cable structures, providing a streamlined alternative to traditional snap-on cores for specific cabling applications.
