Procurement Notes
Verify current lifecycle status as the component is marked as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design specifications before procurement. Check for recommended replacement models if long-term supply stability is required. Validate RoHS compliance documentation upon order confirmation.
Selection Notes
Select this component for applications requiring precise bandpass filtering in the 2.4 GHz ISM band. Consider the 1008 package size for board space limitations. Evaluate thermal requirements against the -40°C to +85°C operating range. Compare electrical characteristics with alternative LTCC filters if specific attenuation profiles are needed. Verify impedance matching for 50 ohm systems.
