MI0805L331R-10

Overview

The MI0805L331R-10 is a single-line ferrite bead from the Laird-Signal Integrity Products MI series, designed for EMI filtering in surface-mount applications. It features an 0805 (2012 Metric) package with dimensions of 2.00mm x 1.25mm and a maximum height of 0.035 inches (0.90mm). The component provides an impedance of 330 Ohms at 100 MHz and supports a maximum current rating of 2A. Its DC resistance (DCR) is maximized at 60 milliohms. It operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Provides high impedance for effective electromagnetic interference suppression on power and signal lines
• Supports high current handling capabilities suitable for demanding circuit applications
• Utilizes a compact surface-mount footprint for efficient board space utilization

Applications

• Power line filtering in electronic circuits
• Signal line noise suppression
• EMI/RFI mitigation in consumer electronics

Procurement Notes

Verify the specific suffix designation during procurement to ensure compliance with environmental regulations, as the MI0805L331R-10 variant is documented as RoHS3 compliant. Confirm that the supplier provides official datasheets matching the manufacturer product number to guarantee authenticity and correct electrical specifications. Cross-reference the package type and terminal configuration to match design requirements.

Selection Notes

Select this component when a 330 Ohm impedance at 100 MHz is required for noise attenuation. Ensure the circuit current does not exceed the 2A rating to prevent performance degradation. The low DC resistance minimizes voltage drop across the component. Verify that the 0805 package size fits the available PCB real estate and that the operating temperature range aligns with the system environment.

Part Context

This part belongs to the MI series of EMI filtering components manufactured by Laird-Signal Integrity Products. The series offers various impedance values and current ratings in standardized packages. The MI0805L331R-10 specifically targets applications requiring moderate impedance with high current capacity in a small form factor, distinguishing it from lower-current or higher-impedance variants in the same family.

Replacement Considerations

Direct substitutes include other 0805 ferrite beads with similar 330 Ohm impedance at 100 MHz and a minimum 2A current rating. Verify that alternative parts maintain comparable DC resistance and physical dimensions to ensure mechanical compatibility.
