Overview
The Würth Elektronik 782429111 is a surface-mount ferrite bead from the WE-CBA series, housed in a 0402 (1005 Metric) package. It provides an impedance of 110 ohms with a tolerance of ±25% and supports a DC current rating of 1.2 A. The component features a maximum DC resistance of 0.09 ohms and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides high-frequency noise suppression through specified impedance characteristics
- Designed for compact surface-mount integration in space-constrained circuits
- Supports continuous direct current operation up to the rated limit
Applications
- High-speed data line filtering
- Power supply output noise reduction
- General-purpose EMI suppression in portable electronics
Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the 0402 package dimensions and electrical ratings match the design requirements before procurement. Check for RoHS compliance status in the latest datasheet.
Selection Notes
Select this component when a low-profile 0402 ferrite bead is required for signal integrity management. Ensure the 1.2 A current rating exceeds the circuit's maximum operating current to prevent saturation. Verify that the 110 ohm impedance at the target frequency aligns with the noise spectrum requiring attenuation.
Part Context
This component belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. These components are engineered for effective electromagnetic interference suppression in modern electronic assemblies where small form factors are critical.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives. Do not assume compatibility based solely on package size or nominal impedance values without cross-referencing detailed electrical specifications.
