Procurement Notes
Verify current lifecycle status as the component may be marked as not recommended for new design or obsolete. Confirm availability through authorized distributors only. Ensure compliance with RoHS3 specifications and EAR99 classification requirements during sourcing. Check for valid datasheet versions before procurement.
Selection Notes
Select this part for applications requiring balanced RF filtering at 2.45 GHz. Consider the 1008 package size for space-constrained PCB layouts. Evaluate the 1.2 dB insertion loss against system link budget requirements. Ensure compatibility with differential signal paths due to the balanced output type.
Part Context
This component belongs to the TDK DEA series of LTCC band pass filters. It shares the same core technology and form factor as variants like DEA252450BT-7012D1 but differs in specific electrical tuning and suffix codes. The series is targeted at high-frequency wireless applications requiring compact, low-loss filtering solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if other DEA series variants with similar center frequencies and balanced outputs can serve as functional replacements after detailed parameter comparison.
