BLM15PX181SN1D

Chip Ferrite Bead Overview

The Murata BLM15PX181SN1D is a single ferrite chip bead designed for electromagnetic interference suppression. It features an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.5 A and exhibits a maximum DC resistance of 90 mOhms. Housed in a compact 0402 (1005 metric) surface-mount package measuring 1.0 mm x 0.5 mm x 0.5 mm, it operates reliably within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation through ferrite material properties
• Enables space-constrained circuit designs via a miniature 0402 footprint
• Maintains signal integrity under continuous direct current loads up to 1.5 A

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Electromagnetic interference suppression in consumer electronics
• Signal conditioning in automotive infotainment systems

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging configuration and terminal finish specifications. Ensure compatibility with standard reflow soldering profiles defined in the manufacturer datasheet. Cross-reference the impedance value at 100 MHz during design validation to guarantee adequate noise suppression performance for the target application frequency spectrum.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required alongside a 180 Ohm impedance rating. Evaluate the 1.5 A current carrying capacity against peak load requirements to prevent saturation. Compare the 90 mOhms DC resistance against voltage drop constraints in low-voltage power distribution networks to ensure efficient operation without excessive thermal generation.

Chip Ferrite Bead Part Context

This part belongs to the BLM15 series of ferrite beads from Murata Electronics. The series offers various impedance values and current ratings within standardized metric packages. These components are engineered for general-purpose EMI suppression in compact electronic assemblies where board real estate is limited.
