Procurement Notes
Verify the current lifecycle status, as documentation indicates this part may be Not Recommended for New Designs (NRND). Confirm RoHS compliance and moisture sensitivity level (MSL 1) requirements during sourcing. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified in the official datasheet.
Selection Notes
Select this component for designs requiring a 2.45 GHz bandpass filter in a 0603 footprint. Consider the 100 MHz bandwidth and 2 dB insertion loss specifications against system link budget requirements. Verify that the operating temperature range of -40°C to +85°C meets environmental constraints.
Part Context
This component belongs to the TDK DEA series of RF filters. It is specifically engineered for ISM band applications, offering a balance between size reduction and performance in wireless connectivity modules. The series is widely used in consumer electronics requiring compact RF front-end solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult TDK technical support or authorized distributors for equivalent LTCC bandpass filters with matching 2.45 GHz center frequency and 0603 package dimensions.
