Overview

The Würth Elektronik 7427927140 is a WE-CBF series surface-mount EMI suppression ferrite bead designed for signal line filtering. It features a compact 0402 (1005 metric) package with dimensions of 1.00mm length, 0.50mm width, and a maximum height of 0.55mm. The component provides an impedance of 47 Ohms at 100 MHz and supports a rated current of 200mA. Its maximum DC resistance is 400 milliohms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

Provides electromagnetic interference suppression for single signal lines through high-frequency impedance characteristics.
Constructed in a small 0402 surface-mount footprint to facilitate dense circuit board layouts.
Engineered for automotive reliability with AEC-Q200 certification and extended thermal stability.

Applications

Signal line filtering in automotive electronic control units
EMI suppression for high-speed data interfaces
Noise reduction in portable digital devices

Procurement Notes

Verify the specific ordering suffix to confirm the correct packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm RoHS3 compliance status and ensure the manufacturer part number matches the design requirements exactly before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0402 package size while maintaining signal integrity. Ensure the circuit's operating current remains below the 200mA rating to prevent saturation. Verify that the 47 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum for effective attenuation.

Part Context

This component belongs to the WE-CBF family of SMD EMI suppression ferrite beads from Würth Elektronik. The series offers various impedance values and package sizes to address diverse filtering needs across industrial and automotive sectors, emphasizing compact form factors and robust performance standards.
