BLM03PG220SZ1D

Chip Ferrite Bead Overview

The Murata BLM03PG220SZ1D is a single-line ferrite bead chip from the EMIFIL BLM03 series, designed for power line noise suppression. It features a 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 with a tolerance of ±25%. It supports a maximum DC current of 900mA and has a maximum DC resistance of 65 milliohms. Operating temperatures range from -55°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on power lines through high-frequency impedance characteristics.
• Features AEC-Q200 qualification for automotive reliability standards.
• Utilizes a compact 0201 footprint suitable for space-constrained printed circuit board layouts.

Chip Ferrite Bead Applications

• Noise filtering in automotive electronic systems
• Power supply line decoupling in portable devices

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ' indicates AEC-Q200 automotive qualification when sourcing. Confirm the manufacturer is Murata Electronics. Ensure the package matches the 0201 metric size. Check RoHS3 compliance status. Validate the impedance value is 22 Ohms at 100 MHz.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring small form factor noise suppression with automotive grade reliability. Compare the 900mA current rating against peak load requirements. Consider the 65 milliohm DC resistance impact on voltage drop. Evaluate the 22 Ohm impedance against target noise frequencies.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM03 series of ferrite beads. It shares the same electrical specifications as the BLM03PG220SN1D but includes the 'SZ' suffix denoting AEC-Q200 qualification. The series offers various impedance values within the 0201 package size.

Chip Ferrite Bead Replacement Considerations

BLM03PG220SN1D is a non-automotive qualified equivalent with identical electrical parameters. Verify if automotive certification is required before substitution.
