PMH0805-800

Overview

The PMH0805-800 is a single-line surface-mount ferrite bead manufactured by Bourns Inc. in the 0805 package. It provides an impedance of 80 ohms at its rated frequency with a maximum DC resistance of 20 milliohms. The component operates within a temperature range of -55°C to +125°C and contains lead, indicating RoHS non-compliance.

Feature Summary

• Single-line configuration for compact circuit integration
• High current handling capability with low DC resistance
• Wide operating temperature range suitable for demanding environments

Applications

• Noise suppression in high-speed digital signal lines
• Power supply filtering for integrated circuits
• EMI reduction in automotive electronic modules

Procurement Notes

Verify RoHS compliance status as this specific part contains lead and is non-compliant with standard environmental directives. Confirm availability as the product may be obsolete or discontinued; check for active substitute part numbers from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a low-impedance path is required for power lines while maintaining noise attenuation capabilities. Ensure the application environment supports lead-containing components and verify that the 0805 footprint aligns with the PCB design constraints.

Part Context

This ferrite bead belongs to Bourns' PMH series of passive components designed for electromagnetic interference suppression. The series offers various impedance values in standard surface-mount packages to support diverse electronic design requirements across industrial and consumer applications.

Replacement Considerations

Check manufacturer documentation for officially confirmed substitute part numbers due to potential obsolescence. Verify equivalent impedance, current rating, and physical dimensions before implementing any alternative component in existing designs.
