7427236

Overview

The Würth Elektronik 7427236 is a flat ferrite core from the WE-FLAT series, designed for suppressing electromagnetic interference in ribbon cables. It features an impedance of 133 Ohms at 100 MHz and operates within a frequency range of 1 MHz to 1 GHz. The component has external dimensions of 82 mm length, 29 mm height, and 23 mm width, with internal dimensions of 62 mm x 11.5 mm. It supports up to 40 poles and functions across a temperature range of -25°C to +125°C.

Feature Summary

• Engineered specifically for flat ribbon cable applications to provide effective common-mode noise suppression.
• Constructed with high-performance ferrite material suitable for broadband interference reduction from 1 MHz to 1 GHz.
• Designed with a full closure structure to accommodate multiple signal lines within a single compact unit.

Applications

• Suppression of electromagnetic interference in multi-line flat ribbon cables
• Noise filtering in computer data transmission lines
• Signal integrity enhancement in high-density electronic assemblies

Procurement Notes

Verify the specific impedance value of 133 Ohms at 100 MHz against your design requirements. Confirm that the internal dimensions of 62 mm by 11.5 mm are compatible with the target ribbon cable thickness and width. Ensure the operating temperature range of -25°C to +125°C meets environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when dealing with wide-bandwidth noise issues in flat cabling where standard round cores cannot fit. The 40-pole capacity allows for consolidating multiple lines into a single suppression point. Consider the physical size constraints carefully, as the external dimensions are larger than typical snap-on rings. This part is ideal for applications requiring robust EMI protection without altering cable routing significantly.

Part Context

This component belongs to the WE-FLAT series, which specializes in ferrite solutions for flat cables. Unlike circular snap-on rings, these cores are molded to match the profile of ribbon cables, ensuring consistent magnetic coupling. The series offers various impedance levels and pole counts to suit different data rates and line configurations.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs before sourcing alternatives.

FAQ

What is the maximum number of poles supported by the 7427236?

The 7427236 supports up to 40 poles, making it suitable for high-density flat ribbon cables.
