BLM31SN500SH1L

Chip Ferrite Bead Overview

The Murata BLM31SN500SH1L is a surface-mount ferrite bead in the BLM31 series, housed in a 1206 (3216 metric) package. It provides an impedance of 50 ohms at 100 MHz with a maximum DC resistance of 1.6 milliohms and supports a continuous current of 12 amperes. The component operates within a temperature range of -55°C to +125°C and features a nickel barrier structure for enhanced solderability.

Chip Ferrite Bead Feature Summary

• Functions as a resistor at noise frequencies to minimize resonance risks
• Nickel barrier electrode structure ensures excellent thermal resistance for soldering
• Designed for use in circuits with unstable ground connections

Chip Ferrite Bead Applications

• EMI suppression on power lines
• Noise filtering in automotive electronics
• General-purpose high-current circuit protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1L against official Murata documentation to confirm package dimensions and termination specifications. Ensure compatibility with RoHS3 standards and check for any recent packaging changes or pinout variations before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring high current handling up to 12A in a compact 1206 footprint. Consider the low DC resistance for minimal voltage drop and the 50-ohm impedance profile for effective broadband noise attenuation in power distribution networks.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM31 series of chip ferrite beads, which are engineered for general use in suppressing electromagnetic interference. The series is characterized by its ability to operate effectively without grounding, making it suitable for various industrial and consumer electronic designs.

Chip Ferrite Bead Replacement Considerations

Consult Murata's official substitution guide for equivalent parts within the BLM31 family. Verify that alternative components match the 1206 package size, 12A current rating, and 50-ohm impedance specifications to ensure functional parity.
