BLM03AG601SN1D

Chip Ferrite Bead Overview

The Murata BLM03AG601SN1D is a single-line ferrite bead chip designed for surface mount applications. It operates within the EMIFIL BLM03 series and utilizes a 0201 (0603 metric) package with dimensions of 0.60mm length, 0.30mm width, and 0.33mm maximum height. The component provides an impedance of 600 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 100mA and features a maximum DC resistance of 1.5 Ohms. The device functions reliably across a temperature range of -55°C to +125°C.

Chip Ferrite Bead Applications

• General purpose EMI suppression filters
• Signal line noise reduction
• Audio line noise filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging configuration and tape specifications. Ensure that the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0201 footprint while maintaining significant noise attenuation at 100 MHz. The 100mA current rating suits low-power signal paths rather than high-current power rails. Consider the 1.5 Ohm DC resistance impact on voltage drop if used in sensitive bias circuits. Verify compatibility with standard reflow soldering profiles for thin profile packages.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM03 series, which focuses on miniaturized noise suppression solutions. The BLM03AG designation indicates a specific material composition optimized for general electronic equipment. It serves as a fundamental passive filter element in modern printed circuit board designs where high-frequency noise control is critical.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers include BLM03HD601SN1D and BLM03HG601SN1D from the same manufacturer. These alternatives offer similar impedance characteristics but may differ in current handling capabilities or DC resistance values. Verify mechanical and electrical compatibility before substitution.
