74275223

Overview

The Würth Elektronik part number 74275223 is a WE-UKW series axial lead ferrite bead designed for signal line noise suppression. It features a radial configuration with a maximum DC current rating of 3A and a maximum DC resistance of 0.02 ohms. The component provides an impedance of 1.24 kOhms at 100 MHz, with an impedance tolerance of ±25%. This single-port device utilizes specific magnetic material properties to attenuate high-frequency electromagnetic interference in electronic circuits.

Feature Summary

• Provides effective attenuation of high-frequency noise on signal lines through magnetic impedance characteristics
• Supports continuous operation with a 3A DC current rating and low DC resistance for minimal signal loss
• Features axial leads suitable for through-hole mounting applications in compact circuit designs

Applications

• Signal line noise suppression in electronic equipment
• High-frequency interference filtering in data transmission lines
• Electromagnetic compatibility enhancement in consumer electronics

Procurement Notes

Verify the exact impedance value and current rating against the official datasheet before integration. Confirm that the axial lead spacing matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Check for any specific handling instructions regarding the fragile ceramic or ferrite core material during assembly.

Selection Notes

Select this component when a through-hole solution is required for signal lines carrying up to 3A. The 1.24 kOhm impedance at 100 MHz makes it suitable for suppressing noise in higher frequency ranges. Consider the physical dimensions and lead form factor compared to surface-mount alternatives if space is constrained. Validate that the ±25% tolerance meets your circuit's noise margin requirements.

Part Context

This part belongs to the WE-UKW series from Würth Elektronik, which specializes in ferrite beads and chips. The series offers various impedance values and current ratings to address different EMI suppression needs. The axial lead design distinguishes it from surface-mount variants, providing mechanical stability for through-hole implementations in industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 1.24 kOhm impedance at 100 MHz, 3A current rating, and 0.02 ohm DC resistance. Verify that alternative components offer compatible axial lead spacing and similar impedance tolerance. Cross-reference material properties to ensure equivalent high-frequency performance and thermal stability in the target application.
