74269244182

Overview

The Würth Elektronik WE-TMSB series component, part number 74269244182, is a surface-mount EMI suppression ferrite bead designed for high-frequency noise attenuation. It features an impedance of 1800 ohms at the standard test frequency and supports a maximum DC current rating of 210 mA. The device utilizes a compact 0402 (1005 metric) package with a low DC resistance of 2.1 ohms. It operates reliably within a temperature range from -55°C to +125°C and carries a tolerance of ±25%.

Feature Summary

• Provides effective electromagnetic interference suppression in compact surface-mount form factors
• Engineered for stable performance across wide industrial temperature ranges
• Designed for integration into space-constrained electronic circuits requiring high-frequency noise filtering

Applications

• High-speed digital signal line filtering
• Power supply output noise suppression
• RF circuit interference mitigation

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before procurement. Confirm that the 0402 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when space constraints necessitate a 0402 footprint while maintaining significant impedance characteristics. Evaluate the 210 mA current limit to ensure it exceeds the maximum expected load current without saturation. Consider the 2.1 ohm DC resistance impact on voltage drop in sensitive power lines. Verify compatibility with standard reflow soldering profiles for SMD assembly.

Part Context

This component belongs to the WE-TMSB series, which focuses on miniaturized EMI suppression solutions. The series offers various impedance values and current ratings within small packages. Würth Elektronik designs these beads to meet stringent automotive and industrial reliability standards, providing consistent performance in noisy environments.

Replacement Considerations

Consult the official datasheet for direct cross-references. Alternative suppliers may offer similar 0402 ferrite beads, but impedance curves and current handling capabilities must be verified. Ensure any substitute matches the physical dimensions and thermal characteristics.
