742792023

Overview

The Würth Elektronik 742792023 is a WE-CBF series SMD EMI suppression ferrite bead designed for signal line filtering. It features an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 3 A with a maximum DC resistance of 30 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

Provides effective electromagnetic interference suppression for high-speed signal lines
Engineered for surface mount assembly in compact electronic designs
Capable of handling high continuous DC currents without saturation

Applications

High-speed data interface protection
Signal integrity enhancement in digital circuits
EMI filtering for USB and other communication ports

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the 0805 footprint matches the target PCB layout constraints. Ensure the selected packaging format aligns with available automated placement equipment capabilities for reliable manufacturing.

Selection Notes

Select this component when signal line filtering requires a balance between high current capacity and moderate impedance at 100 MHz. The 0805 package offers a suitable compromise between performance and board space. Evaluate the thermal environment to ensure operation remains within the specified -55°C to +125°C range during peak load conditions.

Part Context

This ferrite bead belongs to the WE-CBF family from Würth Elektronik, specialized for SMT applications. The series targets EMI/RFI suppression in consumer electronics and industrial systems. It complements other passive components by providing targeted noise attenuation without significantly impacting signal propagation speed or power delivery efficiency.
