Saw Filters Procurement Notes

Verify the exact datasheet revision and pin configuration before integration. Confirm that the 12-SMD no-lead package dimensions align with your PCB footprint design. Ensure the operating temperature range meets your environmental requirements. Cross-reference the manufacturer part number with official TST documentation to avoid counterfeit components.

Saw Filters Selection Notes

Select this component when a 140 MHz center frequency and 14 dB bandwidth are required for SAW filtering. Consider the 12-SMD package size for space-constrained designs. Evaluate the -40°C to +85°C operating range against your system's thermal conditions. Compare performance specifications with alternative filters if stricter bandwidth or frequency stability is needed.
