7427810

Overview

The Würth Elektronik part number 7427810 is a flat ferrite core belonging to the WE-FLAT series, designed for flexible printed circuit boards and data transmission applications. It exhibits an impedance of 130 ohms at 100 MHz. The component features external dimensions of 24 mm in length, 22 mm in width, and 28.5 mm in height, with a cable opening width of 0.8 mm. Constructed from ferrite material, it supports up to one maximum wire configuration. The device complies with RoHS standards and is intended for use in embedded electronics and industrial equipment maintenance scenarios.

Feature Summary

• Designed specifically for flexible printed circuit boards and flat cable applications
• Provides electromagnetic interference suppression with 130 ohm impedance at 100 MHz
• Compact flat geometry suitable for space-constrained embedded electronics

Applications

• Data transmission lines using TWINflex cables
• Embedded electronics assemblies
• Industrial equipment maintenance

Procurement Notes

Verify the specific impedance value of 130 ohms at 100 MHz against your EMI requirements. Confirm the physical dimensions of 24 mm x 22 mm x 28.5 mm fit within the enclosure constraints. Ensure the 0.8 mm opening width accommodates the target flat cable or FPC thickness. Check RoHS compliance documentation if required by your supply chain regulations. Cross-reference the WE-FLAT series designation to ensure compatibility with existing design specifications.

Selection Notes

Select this component when dealing with flexible printed circuits or flat cables requiring EMI suppression in tight spaces. The 130 ohm impedance level is suitable for high-frequency noise attenuation. Consider the single-wire capacity limit when designing harnesses. The flat profile allows for direct mounting on PCBs or integration into cable assemblies without adding significant bulk compared to traditional toroidal cores.

Part Context

This component belongs to the WE-FLAT series from Würth Elektronik, which specializes in ferrite solutions for flexible electronics. The series addresses the growing need for compact EMI suppression in modern embedded systems where standard cylindrical cores are impractical. The 7427810 variant represents a specific dimensional and impedance configuration within this specialized product line.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult Würth Elektronik directly for equivalent alternatives within the WE-FLAT series or other compatible ferrite core families.
