782631182

Overview

The Würth Elektronik 782631182 is a surface-mount ferrite bead from the WE-CBA series, designed for electromagnetic interference (EMI) suppression in high-frequency circuits. Housed in a compact 0603 [1608 Metric] package, this component provides an impedance of 1800 ohms at 100 MHz. It supports a maximum DC current rating of 100 mA and exhibits a maximum DC resistance of 0.75 ohms. The impedance tolerance is specified at ±25%. Constructed with lead-free materials compliant with RoHS standards, it is suitable for automated pick-and-place assembly processes.

Feature Summary

• Provides effective high-frequency noise attenuation through significant impedance characteristics
• Compact 0603 footprint enables dense circuit board layout optimization
• Lead-free construction ensures compliance with environmental directives

Applications

• High-speed digital signal line filtering
• Power supply output noise suppression
• RF circuit EMI mitigation

Procurement Notes

Verify the specific impedance frequency point and DC current limits against your circuit requirements before ordering. Confirm that the 0603 package dimensions align with your PCB land pattern. Ensure the supplier provides valid RoHS compliance documentation to meet regulatory standards for your target market.

Selection Notes

Select this component when space constraints require a small form factor like 0603. Choose based on the required 1800-ohm impedance level for your target noise frequency. Ensure the 100 mA current rating exceeds your application's peak DC load to prevent saturation or excessive heating.

Part Context

This part belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. These components are engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The series offers various impedance values and packages to suit different filtering needs within compact electronic designs.

Replacement Considerations

Consult manufacturer cross-reference lists for verified substitutes. Ensure any alternative maintains identical 0603 dimensions, 1800-ohm impedance, and 100 mA current handling capabilities.
