MU3261-301Y

Overview

The MU3261-301Y is a high impedance chip ferrite bead manufactured by Bourns Inc. in the MU series. It features a 1206 (3216 metric) surface mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 300 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• High impedance characteristics for effective noise suppression
• Surface mount design compatible with automated assembly processes
• Wide operational temperature range suitable for diverse environments

Applications

• Power line filtering
• Signal line filtering
• Electromagnetic interference suppression

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Bourns documentation to ensure correct specifications. Confirm RoHS compliance status and packaging details such as reel or cut tape quantities directly with authorized distributors. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement decisions.

Selection Notes

Select this component when high impedance attenuation is required at 100 MHz within a 1206 footprint constraint. Ensure the application current does not exceed the 300 mA rating to prevent saturation. Verify that the thermal environment remains within the specified -55°C to +125°C operational limits for reliable performance.

Part Context

This ferrite bead belongs to the MU series of high impedance chip beads from Bourns. These components are engineered for compact electronic designs requiring efficient electromagnetic interference mitigation. The 1206 package size balances physical space constraints with adequate current handling capabilities for various consumer and industrial electronics applications.

Replacement Considerations

Public sources indicate that MG, MU, and MZ series parts may be discontinued. Verify availability of direct substitutes through official Bourns channels. Ensure any replacement matches the 1206 package, 300 Ohm impedance, and 300 mA current rating.
