MH3261-260Y

Overview

The Bourns MH3261-260Y is a surface-mount ferrite chip bead designed for electromagnetic interference (EMI) suppression in high-frequency circuits. It features a compact 1206 (3216 metric) package, suitable for dense layouts. The component exhibits an impedance of 26 Ohms at 100 MHz and supports a maximum rated current of 3 A. Its low DC resistance is specified at 40 mOhm, minimizing power loss. The device operates within a temperature range of -55°C to 125°C and has a maximum height of 0.051 inches.

Feature Summary

• Compact 1206 footprint optimized for space-constrained printed circuit board designs
• High current handling capability with low DC resistance to reduce insertion losses
• Wide impedance range providing targeted noise filtering for power and signal lines

Applications

• Filtering noise on high-speed data bus lines
• Suppression of electromagnetic interference in portable electronic devices
• Noise attenuation in power delivery networks for integrated circuits

Procurement Notes

Verify the specific impedance value and tolerance against the manufacturer's official datasheet prior to procurement. Confirm that the 1206 package dimensions and termination style match the target PCB layout requirements. Ensure the operating temperature range and current ratings align with the system's thermal and electrical constraints to guarantee reliable performance under all expected conditions.

Selection Notes

Select this component when a balance between high current capacity and effective high-frequency noise suppression is required in a small form factor. The low DC resistance makes it suitable for applications where voltage drop must be minimized. Consider the 1206 package size relative to available board space and ensure the 3A rating exceeds the peak current demands of the protected circuit line.

Part Context

This ferrite bead belongs to the MH3261-T series from Bourns, Inc., which focuses on high-current EMI suppression solutions. The series is engineered for modern electronics requiring efficient noise control without significant signal degradation or power loss. These components are widely utilized in consumer electronics, computing hardware, and telecommunications equipment to maintain signal integrity.

Replacement Considerations

Consult the official Bourns datasheet for cross-reference information regarding compatible substitute part numbers. Verify that any alternative component matches the 26 Ohm impedance at 100 MHz, 3A current rating, and 1206 package dimensions to ensure mechanical and electrical compatibility.
