Procurement Notes
Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and tape-and-reel specifications. Ensure compatibility with existing PCB footprint requirements and reflow soldering profiles. Cross-reference the part number with authorized distributors to confirm current availability status and authenticity before procurement.
Selection Notes
Select this component when designing circuits requiring precise bandpass characteristics for 2.4 GHz ISM band operations. Consider the insertion loss specifications relative to system sensitivity requirements. Evaluate the physical dimensions and mounting style to ensure integration within the target device's mechanical constraints and assembly processes.
Part Context
This component belongs to Murata's family of ceramic filters, which are widely used in mobile and wireless devices. These filters offer high Q-factor performance and small form factors compared to traditional LC filters. The LFB series is optimized for cost-effective mass production while maintaining reliable RF performance in consumer electronics.
Replacement Considerations
Consult official Murata substitution guides for verified equivalents. Generic replacements may not match the specific insertion loss or bandwidth characteristics required for WLAN/Bluetooth compliance.
