Feature Summary

• Radial leaded construction for through-hole mounting
• High impedance value of 961 ohms for effective noise filtering
• Capable of handling a continuous DC current of 3A

Applications

• EMI suppression in electronic circuits
• Signal line noise filtering
• Power supply output filtering

Procurement Notes

Verify the specific impedance frequency and tolerance requirements against the official datasheet before procurement. Confirm that the radial leaded form factor aligns with the target PCB footprint and assembly process. Ensure the 3A current rating meets the operational load conditions to prevent saturation or thermal issues during use.

Selection Notes

Select this component when high attenuation at specific frequencies is required alongside moderate current handling capabilities. The radial leaded style is suitable for prototyping or applications where surface mount space is constrained but through-hole reliability is preferred. Compare impedance curves with alternative series if broader bandwidth suppression is needed.

Part Context

This component belongs to the WE-UKW series from Würth Elektronik, which specializes in EMI suppression solutions. Ferrite beads in this category are passive components used to dampen high-frequency noise on cables and traces without affecting the desired signal spectrum.
