74278082

Overview

The Würth Elektronik 74278082 is a flat ferrite core designed for flexible printed circuit boards, belonging to the WE-FLAT series. It provides electromagnetic interference suppression with an impedance of 23 ohms at 100 MHz. The component features a width of 11 mm and a thickness of 0.5 mm. Its length specifications range from a minimum of 6 mm to a maximum of 13.5 mm. This design allows for direct integration onto flexible substrates to manage noise in compact electronic assemblies.

Feature Summary

• Engineered specifically for mounting on flexible printed circuit boards
• Provides targeted electromagnetic interference attenuation
• Utilizes a low-profile flat geometry for space-constrained layouts

Applications

• Flexible printed circuit board noise suppression
• Compact consumer electronics assembly
• Portable device signal integrity management

Procurement Notes

Verify the specific length variant required, as the part number covers a range from 6 mm to 13.5 mm. Confirm that the 23 ohm impedance at 100 MHz aligns with the target frequency spectrum. Ensure compatibility with the flexible substrate dimensions before finalizing procurement orders.

Selection Notes

Select this component when standard cylindrical cores cannot fit within the spatial constraints of a flexible PCB layout. The flat profile ensures minimal height increase while maintaining effective high-frequency noise absorption capabilities suitable for sensitive data lines.

Part Context

This component is part of the WE-FLAT product family, which specializes in planar magnetic components. Unlike traditional toroidal or snap-on cores, this series addresses the unique mechanical and electrical requirements of flex circuits, offering a streamlined solution for modern miniaturized electronics manufacturing.

Replacement Considerations

No public confirmed substitute part numbers are available.
