BLM02PX100SN1D

Chip Ferrite Bead Overview

The Murata BLM02PX100SN1D is a single-line ferrite chip bead designed for surface-mount technology. It operates within the BLM02xX_SN series and utilizes a 01005 (0402 metric) package with dimensions of 0.4 mm length, 0.2 mm width, and 0.2 mm height. The component provides an impedance of 10 Ohms at a test frequency of 100 MHz, with a tolerance of 5 Ohms. It supports a maximum DC current of 1.1 A and features a maximum DC resistance of 50 mOhms. The device functions reliably across a temperature range from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through ferrite material characteristics
• Supports automated assembly via standard surface-mount termination
• Maintains signal integrity in compact circuit layouts

Chip Ferrite Bead Applications

• High-density printed circuit board designs requiring minimal footprint
• Power supply line filtering for portable electronic devices
• Signal line protection in mobile communication hardware

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm exact impedance tolerance and packaging configuration. Ensure the selected variant matches the required 01005 package dimensions and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical specifications before procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints necessitate the smallest available ferrite bead package size. The 1.1 A current rating makes it suitable for power lines in battery-operated devices where efficiency is critical. Compare the 10 Ohm impedance specification against other series members to ensure adequate noise attenuation without excessive signal loss at the operating frequency.

Chip Ferrite Bead Part Context

This component belongs to the BLM02xX_SN series, which focuses on miniaturized ferrite beads for modern electronics. The series offers various impedance values within the same 01005 footprint, allowing designers to adjust noise suppression levels while maintaining consistent board layout dimensions. It complements larger packages like the BLM03 or BLM18 series by providing solutions for ultra-compact form factors.

Chip Ferrite Bead Replacement Considerations

BLM02AX100SN1B serves as a comparable alternative within the same series, offering similar impedance but potentially different current handling capabilities. Designers should verify that any substitute maintains the required 01005 package dimensions and meets the specific thermal and electrical requirements of the original design.
