Procurement Notes

Verify the specific part number 74278083 against official Wurth Elektronik documentation to confirm technical specifications. Ensure compliance with RoHS and REACH requirements for your project. Cross-reference datasheets to validate impedance values and dimensional tolerances before procurement.

Selection Notes

Select this component when space constraints require a low-profile ferrite solution for flexible circuits. The 32-ohm impedance at 100 MHz suits high-frequency noise attenuation. Consider the -25°C to +125°C operating range for environmental compatibility. Verify that the 11 mm width fits the target cable or trace geometry.

Part Context

This component belongs to the WE-FLAT series of flat ferrite cores manufactured by Würth Elektronik. These cores are engineered specifically for applications involving flexible printed circuit boards where traditional cylindrical ferrites cannot fit. The series offers various impedance ratings and dimensions to address diverse electromagnetic interference challenges in modern electronics.

Replacement Considerations

Consult official Wurth Elektronik substitution guides for verified alternatives. Generic flat ferrite cores may not match the specific 4W620 material properties or 32-ohm impedance characteristics required for optimal performance.
