782423700

Overview

The Würth Elektronik 782423700 is a surface-mount ferrite bead from the WE-CBA series, designed for signal line noise suppression. It features a 0402 (1005 Metric) package with an impedance of 70 Ohms at 100 MHz. The component supports a maximum DC current rating of 1 A and has a minimum DC resistance of 90 mOhm. It operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides effective high-frequency noise attenuation for sensitive signal lines
• Compact 0402 footprint enables dense PCB layout integration
• Capable of handling continuous DC currents up to 1 Ampere

Applications

• High-speed data interface filtering
• Clock line noise suppression
• General-purpose signal integrity enhancement in consumer electronics

Procurement Notes

Verify the specific ordering code against official Wurth Elektronik documentation to ensure correct impedance and package specifications. Confirm that the selected variant meets all required thermal and electrical ratings for the target application environment before finalizing procurement.

Selection Notes

Select this component when space constraints require a 0402 package size while maintaining a 70 Ohm impedance profile at 100 MHz. Ensure the circuit design accommodates the 1 A current rating and verify compatibility with standard reflow soldering profiles for surface-mount assembly.

Part Context

This ferrite bead belongs to the WE-CBA series, which offers various impedance values in compact packages. It serves as a passive EMI suppression solution, distinct from inductors or capacitors, by dissipating high-frequency energy as heat within the magnetic material structure.

Replacement Considerations

Substitute only with components explicitly listed as cross-references in official Wurth documentation. Verify that any alternative part matches the 0402 dimensions, 70 Ohm @ 100 MHz impedance, and 1 A current rating to maintain circuit performance.
