MU3261-221Y

Overview

The MU3261-221Y is a high impedance chip ferrite bead from the Bourns MU series, designed for surface mount technology in a 1206 (3216 metric) package. It exhibits an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 700 mA and features a maximum DC resistance of 0.35 Ohms. It operates within a temperature range of -55°C to +125°C and has physical dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height.

Feature Summary

• Provides high impedance characteristics for effective noise suppression in electronic circuits
• Utilizes surface mount design compatible with automated assembly processes
• Engineered for stable performance across a wide industrial temperature range

Applications

• Power line filtering in portable devices
• Signal line noise suppression in consumer electronics
• EMI reduction in compact circuit boards

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 the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final application. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for noise control. The 700 mA current rating suits moderate power applications. The 1206 package offers a balance between size and thermal performance. Consider the 0.35 Ohm DC resistance impact on voltage drop in low-voltage circuits.

Part Context

This part belongs to the Bourns MU series of high impedance chip ferrite beads. The series provides various impedance values in standardized SMD packages. These components are widely used for electromagnetic interference suppression in modern electronic designs requiring compact solutions.

Replacement Considerations

Direct substitutes must match the 220 Ohm impedance, 700 mA rating, and 1206 package. Verify equivalent thermal and electrical characteristics before substitution.
