Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update specifications or mechanical drawings over time. Confirm that the SMA connectors match your system requirements. Ensure the operating environment aligns with the component's thermal and power handling limits. Cross-reference the part number ZABP-450-S+ with official Mini-Circuits documentation to confirm current availability and compliance status before finalizing procurement.

Selection Notes

Select this component when a fixed center frequency of 450 MHz is required with a 110 MHz bandwidth. It is suitable for applications needing low insertion loss and high reliability in a compact form factor. Consider the UU1842 package dimensions for board space constraints. Evaluate if the 50Ω impedance matches the surrounding circuitry. This filter is appropriate for S-band applications where lumped LC technology provides sufficient rejection characteristics.
