PMC0603-101

Overview

The PMC0603-101 is a single-line ferrite bead manufactured by Bourns Inc. in the 0603 (1608 metric) surface-mount package. It provides an impedance of 100 ohms at a frequency of 100 MHz. The component supports a maximum current rating of 200 mA and features a low DC resistance of 300 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance for noise suppression in signal lines
• Compact 0603 surface-mount footprint for space-constrained designs
• Low DC resistance minimizes voltage drop in power paths

Applications

• High-speed data line filtering
• Clock signal noise attenuation
• Power supply input filtering for sensitive ICs

Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturing processes may update without changing the part number. Confirm RoHS compliance status with the supplier, as lead-free status can vary by production batch. Ensure the 0603 package dimensions match your PCB land pattern exactly to prevent assembly issues.

Selection Notes

Select this component when a 100-ohm impedance at 100 MHz is required for EMI suppression. The 200 mA current rating limits its use to low-power signal lines rather than main power rails. Consider the 300 milliohm DC resistance impact on signal integrity if used in low-voltage logic circuits.

Part Context

This ferrite bead belongs to Bourns' PMC series of chip ferrites. These components are designed for general-purpose EMI suppression in consumer electronics and telecommunications equipment. The 0603 size offers a balance between performance and board space efficiency compared to larger packages.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with 100 ohms @ 100 MHz impedance and similar current ratings. Verify that replacement parts meet the same -55°C to +125°C operating temperature range and have compatible termination materials for soldering.
