Overview
The Würth Elektronik 742792711 is a WE-CBF series signal line ferrite bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 100 Ohms at 100 MHz with a maximum DC resistance of 300 milliohms and a rated current of 200 mA. The component operates within a temperature range of -55°C to +125°C, featuring a compact footprint of 1.00mm x 0.50mm and a maximum height of 0.55mm.
Feature Summary
- Provides EMI suppression for single signal lines through high-frequency impedance characteristics
- Supports surface-mount assembly in a compact 0402 footprint for space-constrained designs
- Maintains low DC resistance to minimize voltage drop in power-sensitive circuits
Applications
- Signal line filtering in portable electronic devices
- EMI suppression on data transmission lines
- Noise reduction in compact consumer electronics
Procurement Notes
Verify the manufacturer part number 742792711 against official Würth Elektronik documentation to confirm specifications. Ensure the selected packaging type matches production requirements. Cross-reference electrical parameters such as impedance and current rating with the specific datasheet version to avoid integration errors.
Selection Notes
Select this component when a small form factor is required for signal line noise suppression. The 0402 package suits dense PCB layouts. Verify that the 200mA current rating meets circuit demands and that the 100 Ohm impedance at 100 MHz aligns with target noise frequencies. Confirm thermal stability requirements fall within the specified operating range.
Part Context
This component belongs to the WE-CBF series of chip ferrite beads from Würth Elektronik. The series offers various impedance values and packages for EMI suppression applications. The 742792711 specifically targets signal lines requiring compact filtering solutions with defined high-frequency performance characteristics.
Replacement Considerations
Consult official Wurth Elektronik resources for verified substitute part numbers within the WE-CBF series or equivalent product lines. Ensure replacement components match impedance, current rating, and package dimensions.
