PMC0603-102

Overview

The PMC0603-102 is a surface-mount ferrite bead manufactured by Bourns Inc. in the 0603 (1608 metric) package. It provides an impedance of 1 kOhms at 100 MHz with a maximum DC resistance of 1 Ohm and a current rating of 100 mA. The component is designed for noise suppression in high-frequency circuits.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• High-speed data line filtering
• Power supply noise suppression
• RF circuit signal integrity enhancement

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before ordering. Confirm RoHS compliance status as manufacturing processes may vary. Ensure the 0603 footprint matches the target PCB design constraints. Check for any recent lifecycle changes or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for noise filtering. The 100 mA current rating limits its use to low-current signal lines rather than power rails. The 1 Ohm DC resistance minimizes voltage drop in sensitive circuits. Consider thermal dissipation capabilities if operating near maximum current limits.

Part Context

This ferrite bead belongs to Bourns' passive component portfolio, specifically within the ferrite bead and chip category. It serves as a critical element for EMI suppression in modern electronic devices where high-frequency noise control is essential for regulatory compliance and system stability.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with similar 1 kOhm @ 100 MHz specifications, such as the PMC0603-151 or PMC0603-202, provided their current ratings and DC resistance values align with the original design requirements.
