PMC0402-300

Overview

The PMC0402-300 is a surface-mount ferrite bead manufactured by Bourns Inc. It features a 0402 (1005 Metric) package and provides an impedance of 30 Ohms at 100 MHz. The component has a maximum DC resistance of 200 milliohms and supports a continuous current rating of 300 mA.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Designed for compact surface-mount integration in space-constrained circuit layouts

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation
• RF circuit interference suppression

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with standard reflow soldering profiles for the 0402 package. Confirm that the 300 mA current rating meets the operational requirements of the target application circuit.

Selection Notes

Select this component when a low-profile ferrite bead is required for EMI suppression in dense PCB designs. The 30 Ohm impedance value targets specific frequency ranges, while the 300 mA rating suits low-current signal lines. Verify that the 200 milliohm DC resistance does not introduce excessive voltage drop in the power path.

Part Context

This component belongs to the PMC0402 series of ferrite beads from Bourns Inc., designed for general-purpose EMI suppression. The series offers various impedance values within the same 0402 footprint, allowing designers to select appropriate filtering characteristics without altering the board layout.
