PMH1206-700

Overview

The PMH1206-700 is a surface-mount ferrite bead manufactured by Bourns Inc. It features a single-line configuration with an impedance of 70 Ohms at 100 MHz. The component supports a maximum current rating of 3 Amperes and exhibits a low DC resistance of 30 milliohms. Designed for PCB mounting, it operates within a temperature range of -55°C to +125°C. The physical package corresponds to the standard 1206 (3216 metric) footprint.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at target frequencies
• Utilizes a compact surface-mount design suitable for automated assembly processes
• Maintains stable electrical performance across a wide industrial temperature spectrum

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise attenuation in embedded systems
• Signal integrity enhancement in communication interfaces

Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official Bourns datasheet before finalizing circuit designs. Confirm that the selected package dimensions align with the printed circuit board land pattern requirements. Ensure compliance with relevant environmental directives such as RoHS if mandated by the end product specifications.

Selection Notes

Select this component when a single-channel ferrite solution is required for noise suppression on lines carrying up to 3 Amperes. The 70 Ohm impedance value targets specific frequency ranges, typically around 100 MHz. Consider the low DC resistance to minimize voltage drop and power loss in the signal path during normal operation conditions.

Part Context

This ferrite bead belongs to Bourns' PMH series of passive components designed for signal conditioning. It serves as a critical element in managing electromagnetic compatibility within dense electronic assemblies. The 1206 form factor allows for space-constrained layouts while providing effective broadband noise absorption capabilities for sensitive circuitry.

Replacement Considerations

Consult manufacturer cross-reference guides for verified substitutes. Ensure any alternative part matches the 70 Ohm impedance at 100 MHz, 3A current rating, and 1206 package dimensions to maintain circuit performance and mechanical fit.
