MU1005-301Y

Overview

The MU1005-301Y is a high impedance chip ferrite bead manufactured by Bourns Inc. in the 0402 (1005 metric) surface mount package. It provides an impedance of 300 Ohms at 100 MHz with a maximum DC resistance of 500 mOhm and a current rating of 100 mA. The component operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference filtering for signal lines
• Compact surface mount design suitable for space-constrained applications

Applications

• EMI suppression in portable electronic devices
• Signal line filtering in consumer electronics
• Noise reduction in compact circuit boards

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Bourns datasheet before procurement. Confirm that the 0402 package dimensions align with the target PCB footprint. Ensure the 100 mA current rating meets the operational requirements of the specific circuit application to prevent performance degradation.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for EMI suppression in tight spaces. The 0402 package offers a small footprint compared to larger ferrite beads. Consider the 100 mA current limit and 500 mOhm DC resistance to ensure compatibility with the power budget and signal integrity needs of the design.

Part Context

This part belongs to Bourns' MU series of high impedance chip ferrite beads. These components are designed for noise suppression in digital circuits and data lines. The series includes various impedance values and current ratings, all housed in standard SMD packages like the 0402 form factor used in this model.

Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 300 Ohm impedance at 100 MHz in a 0402 package. Verify that alternative parts meet the same 100 mA current rating and -55°C to +125°C operating temperature range to ensure functional equivalence.
