Procurement Notes

Verify the specific datasheet revision to confirm mechanical dimensions and electrical tolerances match your schematic requirements. Ensure compatibility with your PCB footprint, specifically the 3.0x3.0 mm 6-pad SMD configuration. Confirm that the operating temperature range aligns with your environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a 2492 MHz center frequency and narrow 5 MHz bandwidth are required for RF filtering. Consider its small form factor for space-constrained designs. Evaluate insertion loss characteristics against system sensitivity requirements. Compare performance metrics with alternative SAW filters if wider bandwidth or different frequency bands are needed.
