PMH1210-500

Overview

The PMH1210-500 is a surface-mount ferrite bead manufactured by Bourns Inc. in a 1210 package. It provides an impedance of 50 Ohms at 100 MHz with a maximum DC resistance of 30mOhm and a current rating of 3A. The component operates within a temperature range of -55°C to 125°C.

Feature Summary

• Single-line configuration for noise suppression
• Compact surface-mount design

Applications

• Noise reduction in electronic circuits

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Bourns Inc. or authorized distributors before procurement. Ensure the 1210 footprint matches the target PCB layout and confirm that the 3A current rating meets the application's peak load requirements without exceeding thermal limits.

Selection Notes

Select this component when a 50 Ohm impedance at 100 MHz is required for EMI filtering. The 3A current rating supports moderate power lines, while the low DCR minimizes voltage drop. Verify that the operating temperature range covers the environmental conditions of the final assembly.

Part Context

This ferrite bead belongs to Bourns' PMH series of surface-mount magnetic components. These parts are designed for high-frequency noise attenuation in compact electronic designs. The 1210 case size offers a balance between current handling capability and spatial efficiency for modern circuit boards.

Replacement Considerations

Consult official substitution guides for equivalent ferrite beads with matching 50 Ohm impedance and 1210 footprint. Verify that alternative components meet the same 3A current rating and 30mOhm DCR specifications to ensure circuit performance parity.
