742792624

Overview

The Wurth Elektronik part number 742792624 is a Surface Mount Device (SMD) EMI suppression ferrite bead belonging to the WE-CBF series. It utilizes a high-current 0603 package format with dimensions of 1.6 mm length, 0.8 mm width, and 0.5 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz. It is rated for a maximum DC current of 1.5 A and features a maximum DC resistance of 100 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• High-current capability suitable for power line filtering applications
• AEC-Q200 automotive qualification ensuring reliability in harsh environments
• Compact 0603 surface mount footprint for space-constrained designs

Applications

• Automotive electronics power supply filtering
• EMI suppression on high-current data lines
• DC-DC converter output noise reduction

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to ordering. Confirm that the 0603 package dimensions align with your PCB land pattern requirements. Ensure the selected component meets the required AEC-Q200 standards if used in automotive contexts. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a compact SMD ferrite bead is needed for high-current applications requiring 180 Ohms impedance at 100 MHz. The 0603 size offers a balance between current handling capacity and board space efficiency. Consider the 100 mOhms maximum DC resistance to minimize voltage drop in power paths. Verify thermal performance under continuous load conditions within the specified operating temperature range.

Part Context

This component is part of Wurth Elektronik's WE-CBF series, which specializes in high-current EMI suppression solutions. The series is designed to meet the rigorous demands of modern electronic systems, particularly those requiring robust noise filtering in limited spaces. The AEC-Q200 certification indicates suitability for automotive-grade applications, distinguishing it from standard commercial-grade ferrite beads.

Replacement Considerations

Consult the official Wurth Elektronik documentation for verified substitute part numbers within the WE-CBF series or equivalent high-current ferrite beads from other manufacturers. Ensure any replacement matches the 0603 package dimensions, 180 Ohm impedance at 100 MHz, and 1.5 A current rating.
