74279213

Overview

The Würth Elektronik 74279213 is a surface-mount ferrite bead from the WE-CBF series, designed for high-speed EMI suppression. It features a 1206 (3216 Metric) package with dimensions of 3.2 x 1.6 x 1.1 mm. The component provides an impedance of 600 Ohms at 100 MHz and supports a maximum DC current of 200 mA. Its maximum DC resistance is 0.3 Ohms with a tolerance of ±25%. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed signal lines
• Utilizes a compact surface-mount design suitable for space-constrained PCB layouts
• Constructed with shielded architecture to minimize external magnetic field leakage

Applications

• High-speed data line filtering in digital communication interfaces
• EMI suppression on USB and other peripheral signal traces
• Noise reduction in portable electronic devices and mobile hardware

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 1206 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 600 Ohm impedance at 100 MHz is required for noise attenuation. The 200 mA current rating suits low-power signal lines rather than power delivery paths. The shielded construction is advantageous where magnetic coupling to adjacent components must be minimized. Consider the 0.3 Ohm DC resistance impact on signal integrity.

Part Context

This part belongs to the WE-CBF series of ferrite beads and chips from Würth Elektronik. These components are engineered for broadband noise suppression in modern electronics. The series offers various impedance values and current ratings to suit different circuit needs while maintaining a consistent small-footprint form factor for automated assembly.

Replacement Considerations

Direct substitutes include other 1206 ferrite beads with similar 600 Ohm impedance and 200 mA current ratings. Verify that any alternative maintains the same shielded structure and thermal characteristics. Cross-reference impedance curves to ensure equivalent performance across the target frequency spectrum.
