Procurement Notes

Verify current availability status as this component is marked Not Recommended for New Designs. Confirm that existing inventory meets project requirements before finalizing procurement plans. Check for official End-of-Life notifications or Product Change Notices to ensure long-term supply chain stability. Ensure compatibility with existing PCB layouts and soldering profiles.

Selection Notes

Select this component only if the specific 2.45 GHz center frequency and 100 MHz bandwidth align with system specifications. Consider the 1.7 dB insertion loss impact on overall link budget. Evaluate the 0603 footprint constraints against available board space. Assess thermal operating range limits against environmental conditions. Review alternative components if new design approval is required.

Part Context

This part belongs to the TDK DEA series of RF filters, specifically engineered for ISM band applications. The DEA series utilizes LTCC construction to achieve high Q-factor and precise frequency characteristics in small form factors. These filters are commonly integrated into wireless communication devices requiring reliable signal conditioning and interference rejection.
