BLM31PG330SZ1L

Chip Ferrite Bead Overview

The Murata BLM31PG330SZ1L is a surface-mount ferrite bead from the BLM31P series, designed for EMI suppression in continuous voltage lines. It features a 1206 (3216 metric) package with dimensions of 3.2mm length, 1.6mm width, and 1.1mm height. The component provides an impedance of 33 Ohms at 100 MHz with a maximum DC resistance of 9mΩ. It supports a rated current of 6A and operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Functions as a resistor at noise frequencies to reduce resonance without distorting signal waveforms
• Nickel barrier structure on external electrodes provides excellent soldering thermal resistance
• Designed for use in circuits with unstable ground connections due to lack of grounding requirement

Chip Ferrite Bead Applications

• Power supply line filtering
• EMI suppression in continuous voltage lines
• General use applications requiring high current handling

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1L' against official Murata documentation to confirm exact termination and packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when designing power lines requiring high current capacity up to 6A alongside effective high-frequency noise attenuation. The low DC resistance minimizes power loss, while the 1206 footprint offers a balance between current handling and board space efficiency for general electronic equipment.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM31P series of chip ferrite beads. These components are unshielded single-type beads intended for general-purpose EMI suppression. They operate effectively without a ground connection, making them suitable for various digital and analog circuits where stable grounding is difficult to achieve.

Chip Ferrite Bead Replacement Considerations

Check for other BLM31P series variants with identical 33 Ohm impedance and 6A current rating. Verify that any substitute maintains the same 1206 package dimensions and operating temperature range to ensure mechanical and electrical compatibility.
