782429152

Overview

The Würth Elektronik 782429152 is a surface-mount ferrite bead from the WE-CBA series, housed in a 0402 (1005 Metric) package. It provides an impedance of 1500 Ohms at 100 MHz with a maximum DC resistance of 0.5 Ohms and a current rating of 500 mA. The component operates within a temperature range of -55°C to 125°C and has a maximum height of 0.5 mm.

Feature Summary

• Provides high impedance for effective noise suppression in compact designs
• Supports low-current signal lines with minimal DC voltage drop
• Complies with AEC-Q200 qualification standards for automotive reliability

Applications

• Automotive electronics requiring AEC-Q200 qualified components
• High-frequency noise filtering on data and power lines
• Compact consumer electronic devices with limited board space

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 0402 package dimensions align with the PCB footprint design. Ensure the selected component meets the required operating temperature range for the target application environment.

Selection Notes

Select this component for applications requiring significant attenuation of high-frequency interference in tight spaces. The 500 mA rating suits low-power signal paths rather than high-current power distribution. Consider the 0.5 Ohm DC resistance impact on signal integrity when designing sensitive circuits.

Part Context

This ferrite bead belongs to the WE-CBA series, designed for surface-mount technology. It utilizes specialized ferrite materials to achieve stable performance across wide temperature variations. The 0402 form factor allows for automated placement in dense assembly processes.

Replacement Considerations

Check for direct substitutes within the WE-CBA series offering similar impedance curves. Verify that alternative packages maintain compatible thermal and mechanical characteristics for the existing layout.
