PMH0805-100

Overview

The PMH0805-100 is a multilayer high-current ferrite chip bead from the PMH series by Bourns Inc. It features an 0805 surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 0.90mm. The component provides an impedance of 10 ohms at 100 MHz and operates with a current rating of 6 Amperes. It is designed for noise suppression in power lines.

Feature Summary

• Multilayer construction for high current handling capabilities
• Surface mount design for automated assembly
• Ferrite material for effective high-frequency noise attenuation

Applications

• Power supplies
• Battery chargers
• Portable devices

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance for this specific part number. Confirm exact impedance values and current ratings against the official datasheet before integration. Ensure the supplier provides authentic documentation to validate performance specifications.

Selection Notes

Select this component for applications requiring high current capacity in a compact footprint. Evaluate the 10-ohm impedance characteristic against target noise frequencies. Consider the 0805 package size constraints within the PCB layout for adequate spacing and thermal management.

Part Context

This ferrite bead belongs to the PMH series, which focuses on multilayer high-current solutions. It serves as a passive component for electromagnetic interference suppression in electronic circuits, distinct from resistors or inductors used for signal processing.

Replacement Considerations

Consult official substitution guides for equivalent impedance and current ratings. Verify package compatibility and mounting requirements before replacing with alternative ferrite beads from other manufacturers.
