Procurement Notes

Verify component obsolescence status prior to procurement as the DEA162450BT-1247C1 is listed as obsolete and no longer manufactured. Confirm availability through authorized distributors or secondary markets if existing stock is required. Ensure compatibility with replacement components such as similar series filters before finalizing supply chain decisions. Review datasheet specifications carefully to validate electrical parameters against current design requirements.

Selection Notes

Select this component only if its specific 2.45 GHz center frequency and 100 MHz bandwidth align precisely with system requirements. Consider the 50 ohm impedance matching for proper circuit integration. Evaluate the 0603 package dimensions against board space constraints. Assess thermal stability within the -40°C to +85°C range for environmental suitability. Prioritize verified substitutes due to the part's discontinued status.
