742792655

Overview

The Würth Elektronik 742792655 is a single-line surface-mount EMI suppression ferrite bead from the WE-CBF series. It features a 0603 (1608 metric) package with dimensions of 1.60 mm length, 0.80 mm width, and 1.00 mm maximum height. The component provides an impedance of 600 ohms at a test frequency of 100 MHz. It supports a maximum DC current of 100 mA and has a maximum DC resistance of 900 milliohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance for effective electromagnetic interference suppression in signal lines
• Designed for compact surface-mount applications using standard 0603 footprints
• Constructed as a multilayer SMD ferrite component for reliable performance

Applications

• Signal line filtering in electronic circuits
• EMI suppression in compact consumer electronics
• Noise reduction in portable devices requiring small form factors

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure accuracy. Confirm that the 0603 package size and 600-ohm impedance specifications match the design requirements. Check for any product change notices or end-of-life announcements associated with this component identifier before finalizing procurement plans.

Selection Notes

Select this component when space constraints necessitate a 0603 footprint while requiring significant noise attenuation at 100 MHz. Ensure the circuit current does not exceed the 100 mA rating to prevent saturation. Consider the 900 milliohm DC resistance impact on signal integrity and power loss in low-voltage applications.
