PMC0805-202

Overview

The PMC0805-202 is a surface-mount ferrite bead manufactured by Bourns Inc. in the 0805 (2012 Metric) package. It provides an impedance of 2 kOhms at 50 MHz and has a maximum DC resistance of 1.5 Ohms. The component supports a current rating of 100mA and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Provides high impedance for electromagnetic interference suppression
• Designed for surface mount assembly processes
• Constructed with lead-free materials

Applications

• General purpose noise filtering in electronic circuits
• Signal line protection in consumer electronics
• Power supply output filtering

Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturer documentation may update thermal or electrical limits over time. Confirm that the 0805 footprint matches the target PCB layout dimensions precisely. Ensure the selected supplier can provide traceability documentation required for quality assurance protocols.

Selection Notes

Select this component based on the requirement for 2 kOhm impedance at 50 MHz. Verify that the 100mA current rating meets the circuit's operational needs without saturation. Check that the 1.5 Ohm DC resistance does not cause unacceptable voltage drop in the signal path.

Part Context

This part belongs to the Bourns ferrite bead and chip product line. It is designed for compact electronic designs requiring effective high-frequency noise attenuation. The 0805 package allows for automated placement in standard surface mount manufacturing lines.

Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Do not assume functional interchangeability with generic ferrite beads from other manufacturers due to potential differences in impedance curves and current handling capabilities.
