Procurement Notes

Verify the specific datasheet version for precise mechanical dimensions and thermal characteristics before integration. Confirm that the 16-SMD no-lead package footprint matches your PCB layout requirements. Ensure operating conditions remain within the specified temperature range to maintain the stated ±0.25 dB temperature stability. Cross-reference the manufacturer's part number CSBP-A940+ with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a narrow bandpass response centered at 940 MHz is required for GSM or cellular applications. The ceramic resonator construction offers superior stability compared to LC filters in high-power scenarios. Consider the 16-lead SMD package for automated surface-mount assembly processes. Evaluate the 120 MHz bandwidth against system channel spacing requirements to ensure adequate isolation from adjacent signals.
