Chip Ferrite Bead datasheet and documents for BLM21BB471SZ1D
Chip Ferrite Bead Overview
The Murata BLM21BB471SZ1D is a single-line chip ferrite bead in the BLM21_Z series, housed in an unshielded 0805 (2012 metric) surface-mount package. It provides 470 Ohms impedance at 100 MHz with a 25% tolerance and supports a maximum DC current of 400 mA. The component features a maximum DC resistance of 400 mOhms and operates within a temperature range of -55°C to +125°C. It meets AEC-Q200 automotive qualification standards.
Chip Ferrite Bead Feature Summary
- Provides high-impedance noise suppression for single signal lines in compact surface-mount designs
- Engineered for robust performance under automotive environmental conditions
- Constructed as an unshielded chip bead to minimize electromagnetic interference
Chip Ferrite Bead Applications
- Automotive electronic circuit noise filtering
- High-speed signal line protection
- General-purpose EMI suppression in consumer electronics
Chip Ferrite Bead Procurement Notes
Verify the specific suffix 'Z1' against official documentation to confirm exact manufacturing specifications. Ensure compatibility with standard 0805 footprints during layout. Confirm RoHS compliance status through the manufacturer's latest datasheet before final integration into production assemblies.
Chip Ferrite Bead Selection Notes
Select this component when a 470 Ohm impedance value is required at 100 MHz for single-line applications. The 400 mA current rating suits moderate power circuits. The AEC-Q200 qualification makes it suitable for automotive environments requiring extended temperature stability and reliability compared to standard commercial grades.
Chip Ferrite Bead Part Context
This part belongs to the Murata BLM21 series of ferrite beads, designed for suppressing electromagnetic interference in digital and analog circuits. The BLM21BB variant specifically denotes the 0805 package size and material composition optimized for high-frequency noise attenuation while maintaining low DC resistance.
Chip Ferrite Bead Replacement Considerations
BLM21BD471SN1D offers similar electrical characteristics but may differ in current handling or packaging details. Verify pinout and impedance curves against the original design requirements before substitution.
