MU1005-300Y

Overview

The MU1005-300Y is a single-line surface-mount ferrite bead manufactured by Bourns Inc. It features an impedance of 30 Ohms at 100 MHz and supports a maximum DC current of 300 mA. The component has a maximum DC resistance (DCR) of 200 mOhms and a tolerance of ±25%. It utilizes the 0402 (1005 Metric) package size, measuring approximately 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height.

Feature Summary

• Provides high impedance for noise suppression on power and signal lines
• Compact surface-mount design suitable for space-constrained applications
• Single-line configuration for targeted filtering

Applications

• Noise suppression in portable electronic devices
• Filtering on data lines within compact circuits
• EMI reduction in mobile communication hardware

Procurement Notes

Verify the manufacturer is Bourns Inc. when sourcing this specific part number. Confirm the package type is 0402 (1005 Metric). Ensure the impedance rating matches the requirement of 30 Ohms at 100 MHz. Check that the current rating meets the circuit's maximum DC current needs of 300 mA. Validate the DCR specification does not exceed 200 mOhms for proper signal integrity.

Selection Notes

Select this component when a low-profile ferrite bead is required for EMI suppression in tight spaces. The 0402 package allows for high-density PCB layouts. The 300 mA current rating suits moderate power applications. Consider the 30 Ohm impedance at 100 MHz for effective noise attenuation in that frequency range. Ensure the 200 mOhm DCR aligns with voltage drop constraints in the design.
