Procurement Notes

Verify the specific ordering suffix and case style (NC1916) against current Mini-Circuits documentation to ensure compatibility with your assembly process. Confirm RoHS and REACH compliance status as required by your regulatory standards. Cross-reference the electrical specifications with your system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a narrow 20 MHz bandwidth centered at 897 MHz is required. Ensure the PCB layout accommodates the SMT package dimensions and thermal requirements for 40 dBm power handling. Verify that the 50 Ohm impedance matches the surrounding circuit topology to minimize signal reflection.

Part Context

This part belongs to Mini-Circuits' CBP series of ceramic coaxial resonator bandpass filters. These components are designed for general-purpose RF applications requiring reliable frequency selection. The series offers various center frequencies and bandwidths to suit different communication bands while maintaining consistent performance characteristics across the product line.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct replacements. Verify that any alternative maintains the same center frequency, bandwidth, and impedance specifications. Ensure mechanical footprint compatibility if space constraints exist in the existing design.
