Overview
The Würth Elektronik 782429182 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0402 (1005 metric) package and provides an impedance of 1800 Ohms at 100 MHz. The component has a rated current of 210 mA and a DC resistance of 2.1 Ohms. Designed for single signal line applications, it offers compact EMI filtering suitable for space-constrained PCB layouts.
Feature Summary
- Provides high impedance for effective EMI noise suppression in single signal lines
- Utilizes a compact 0402 surface-mount footprint for dense board integration
- Engineered with low DC resistance to minimize signal loss
Applications
- Single signal line EMI filtering
- Space-constrained PCB designs requiring compact components
- General-purpose noise suppression in electronic circuits
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the operating conditions do not exceed the specified 210 mA rated current to maintain performance integrity.
Selection Notes
Select this component when high impedance at 100 MHz is required within a minimal 0402 footprint. Consider the 2.1 Ohm DC resistance impact on signal integrity. Evaluate if the 210 mA current rating meets the circuit's operational demands without saturation.
Part Context
This part belongs to the WE-CBA series of surface-mount ferrite beads manufactured by Würth Elektronik. These components are designed for EMI suppression in portable and compact electronic devices where space is limited.
