Procurement Notes

Verify the exact datasheet revision when sourcing, as specifications may vary slightly between production batches. Confirm that the 12-SMD package dimensions align with your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles suitable for ceramic components. Cross-reference the manufacturer part number to avoid confusion with similar series filters.

Selection Notes

Select this component when a fixed center frequency near 1905 MHz is required with moderate bandwidth. The ceramic construction offers reliability in environments where temperature stability is critical. Consider the insertion loss range when designing for low-noise applications. Verify that the SMD package fits within the available space constraints of the target assembly.
