Overview
The Würth Elektronik 7427927130 is a WE-CBF series ferrite chip bead designed for signal line EMI suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.55mm. The component provides an impedance of 30 Ohms at 100 MHz and supports a rated current of 300mA. Its DC resistance is maximized at 150 milliohms. It operates within a temperature range of -55°C to +125°C and is available in tape and reel packaging.
Feature Summary
- Provides electromagnetic interference suppression for single signal lines
- Utilizes a compact 0402 surface-mount footprint for space-constrained designs
- Constructed from multilayer SMD ferrite material for stable performance
Applications
- Signal line filtering in electronic circuits
- EMI suppression in portable digital devices
- High-frequency noise reduction in compact PCB layouts
Procurement Notes
Verify the obsolete status indicated by PCN 742792yyy dated March 1, 2023. Confirm availability of recommended substitutes such as part number 74279276. Ensure compliance with RoHS3 specifications and EAR99 classification requirements during sourcing. Check moisture sensitivity level 1 handling procedures.
Selection Notes
Select this component for applications requiring low-profile signal line filtering. The 0402 package suits dense board layouts. Evaluate the 300mA current rating against circuit load requirements. Consider the 30 Ohm impedance at 100 MHz for target frequency attenuation needs. Verify thermal stability within the specified operating range.
Part Context
This ferrite bead belongs to the WE-CBF series, which includes various sizes and impedance values. It is categorized under EMI/RFI filters and ferrites. The product family supports automotive standards like AEC-Q200, though specific qualification for this exact part number requires datasheet confirmation. It serves as a passive component for noise control.
Replacement Considerations
Würth Elektronik recommends part number 74279276 as a substitute. Verify electrical compatibility including impedance and current ratings before substitution. Review the Product Change Notification for manufacturing updates.
