MU1005-471Y

Overview

The MU1005-471Y is a high impedance chip ferrite bead manufactured by Bourns Inc. in the 0402 (1005 metric) surface mount package. It provides an impedance of 470 Ohms at a test frequency of 100 kHz with a tolerance of 25%. The component supports a maximum DC current of 100 mA and exhibits a maximum DC resistance of 650 mOhms.

Feature Summary

• Provides high impedance for effective noise suppression in compact designs
• Utilizes a single-line configuration for signal line filtering
• Constructed as a surface mount device for automated assembly

Applications

• High-frequency noise suppression on data lines
• Signal integrity enhancement in portable electronics
• EMI reduction in compact consumer devices

Procurement Notes

Verify the specific datasheet version to confirm impedance characteristics, as ferrite beads often exhibit frequency-dependent behavior. Ensure the selected component meets the required DC current rating for the target circuit application. Confirm RoHS compliance status through official manufacturer documentation before integration into production.

Selection Notes

Select this component when space constraints require a 0402 footprint for EMI filtering. Evaluate the 100 mA current limit against peak load requirements to prevent saturation. Consider the 650 mOhms DC resistance impact on voltage drop within low-voltage signal paths during design validation.

Part Context

This part belongs to Bourns' line of high impedance chip ferrite beads. These components are designed to attenuate electromagnetic interference in high-speed digital circuits. The 0402 package allows for dense PCB layouts typical in modern mobile and wearable technology applications requiring minimal board space.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering 470 Ohms impedance. Verify that substitute parts match the 100 mA current rating and physical dimensions to ensure compatibility with existing footprints and thermal profiles.
