BLM03PG220SN1D

Chip Ferrite Bead Overview

The BLM03PG220SN1D is a single-line ferrite bead from the Murata EMIFIL BLM03 series, designed for power line noise suppression. It features a compact 0201 (0603 metric) surface-mount package with dimensions of 0.60mm length and 0.30mm width. The component provides an impedance of 22 Ohms at 100 MHz and supports a maximum DC current of 900mA. Its maximum DC resistance is 65 milliohms, ensuring minimal signal loss in high-frequency applications.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on single power lines through high-impedance characteristics at target frequencies.
• Utilizes a miniature 0201 footprint to maximize board space efficiency in dense electronic designs.
• Engineered for stable performance across a wide operating temperature range from -55°C to +125°C.

Chip Ferrite Bead Applications

• Noise filtering for portable electronic devices
• Power supply line decoupling in consumer electronics
• EMI suppression in compact circuit boards

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging and tape specifications. Ensure compatibility with standard 0201 reflow soldering profiles. Confirm RoHS3 compliance status directly from the manufacturer datasheet prior to integration into regulated assemblies.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0201 package size while maintaining adequate current handling for low-power circuits. The 22 Ohm impedance value is suitable for attenuating high-frequency noise without significantly impacting DC voltage levels. Compare against larger packages like 0603 if higher current ratings are required.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM03 series of chip ferrite beads, which are optimized for small form factors. The series offers various impedance and current combinations within the 0201 package, allowing designers to tailor noise suppression capabilities to specific power rail requirements in mobile and handheld devices.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM03PG220SN1D variants or equivalent 0201 ferrite beads with matching 22 Ohm impedance and 900mA rating. Verify physical dimensions and terminal configurations before substitution.
