MI0603J680R-10

Overview

The MI0603J680R-10 is a single-line ferrite bead from the Laird MI series, designed for EMI filtering in surface-mount applications. It features a 0603 (1608 Metric) package with dimensions of 1.60mm length and 0.80mm width. The component provides an impedance of 68 Ohms at 100 MHz and supports a maximum rated current of 1A. Its maximum DC resistance is 100 milliohms, ensuring minimal signal loss. It operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression for high-frequency noise on power and signal lines.
• Utilizes a compact monolithic ceramic structure suitable for dense surface-mount PCB layouts.
• Maintains low DC resistance to preserve signal integrity while attenuating unwanted RF energy.

Applications

• Power supply line filtering in portable electronic devices
• Signal line noise suppression in consumer electronics
• EMI mitigation in automotive infotainment systems

Procurement Notes

Verify the specific suffix '10' corresponds to the required packaging format, as ordering suffixes may indicate reel or cut tape variations without altering electrical function. Confirm RoHS3 compliance status against the latest manufacturer datasheet before finalizing procurement specifications for regulated markets.

Selection Notes

Select this component when a 68 Ohm impedance at 100 MHz is required for a 0603 footprint. Ensure the circuit current does not exceed 1A to prevent saturation. Compare DCR values against other series members if low insertion loss is critical. Verify thermal management requirements given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the Laird MI series of multilayer ferrite beads, which are engineered for broadband noise suppression. The series offers various impedance values and current ratings across standard metric packages like 0402, 0603, and 0805. These components serve as passive filters to protect sensitive circuits from conducted electromagnetic interference.

Replacement Considerations

MI0603J680R-00 is listed as a discontinued direct substitute option by distributors, though availability should be verified. Other 0603 ferrite beads with 68 Ohm @ 100 MHz and 1A rating may serve as functional equivalents if pin compatibility and impedance curves match.
