MU3261-801Y

Overview

The MU3261-801Y is a high impedance ferrite chip bead from the Bourns MU series, designed for surface mount applications. It features a 1206 (3216 metric) package with an impedance of 800 ohms at 100 MHz and a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 150 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• High impedance characteristics for effective noise suppression in high-frequency circuits
• Compact 1206 surface mount footprint suitable for space-constrained designs
• Robust thermal stability across a wide operating temperature range

Applications

• High frequency signal line filtering
• Power supply noise suppression
• EMI/RFI attenuation in compact electronic devices

Procurement Notes

Verify the specific impedance value and current rating against the official Bourns datasheet before integration. Confirm that the 1206 package dimensions align with your PCB layout constraints. Ensure the supplier provides documentation confirming RoHS compliance and the exact manufacturing batch details for traceability purposes.

Selection Notes

Select this component when high impedance at 100 MHz is required within a standard 1206 footprint. Consider the 300 mA current limit for power line applications. Compare against other MU series variants if different impedance or current ratings are needed for the specific circuit requirements.

Part Context

This part belongs to the Bourns MU series of high impedance ferrite beads. The series offers various impedance values and current ratings in standardized packages. The MU3261-801Y specifically targets applications requiring significant attenuation at 100 MHz while maintaining a low profile.

Replacement Considerations

Check for direct substitutes within the MU series such as MU3261-101Y for lower impedance needs. Verify pin compatibility and impedance curves for any cross-references from other manufacturers to ensure functional equivalence.
