PMC0603-300

Overview

The PMC0603-300 is a surface-mount ferrite bead manufactured by Bourns Inc. in the 0603 (1608 Metric) package. It provides an impedance of 30 Ohms at 100 MHz with a maximum DC resistance of 200 mOhm and a rated current of 200 mA. The component is designed for single-line noise suppression applications.

Feature Summary

• Provides high impedance to suppress electromagnetic interference in high-frequency circuits
• Compact 0603 surface-mount footprint suitable for space-constrained designs
• Low DC resistance minimizes voltage drop across the signal path

Applications

• High-speed data line filtering
• Power supply noise suppression
• Clock signal conditioning

Procurement Notes

Verify component status as this specific part number may be obsolete or discontinued. Confirm availability of equivalent series components such as the PMC0603-RC series if direct replacement is required. Ensure compliance with current environmental regulations including RoHS standards before procurement.

Selection Notes

Select based on required impedance at target frequency and current handling capabilities. The 0603 package size dictates board space requirements. Verify that the 200 mA rating meets circuit load demands and that the 200 mOhm resistance does not exceed allowable voltage drop limits for the application.

Part Context

This component belongs to Bourns' passive filter portfolio, specifically ferrite beads used for EMI suppression. It serves as a passive component to attenuate high-frequency noise without affecting lower frequency signals or DC power delivery.

Replacement Considerations

Public sources indicate available substitutes include the PMC0603-RC series and MG1608-300Y. Verify electrical parameters match exactly when substituting.
