Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 3116 package dimensions align with your PCB footprint requirements. Ensure that the thermal management capabilities meet the operational temperature range specifications for your intended environment. Cross-reference the part number to avoid confusion with similar models in the HF series.

Selection Notes

Select this component when a high-pass filter with a cutoff near 850 MHz is required in a compact form factor. The 50 Ohm impedance matches standard RF system designs. Consider the 3116 package size for space-constrained layouts. Evaluate the insertion loss and power handling against system requirements. Compare against other HF series variants if different frequency bands or package sizes are needed.

Part Context

This part belongs to the KYOCERA AVX HF series of thin-film high-pass filters. These components are engineered for radio frequency applications, offering consistent performance across a wide temperature range. The series is known for its reliability and suitability for mass production due to its surface-mount design. It complements other RF components like SAW filters and duplexers in complex signal chains.

Replacement Considerations

Consult official substitution lists for equivalent high-pass filters within the same impedance and package constraints. Verify that any alternative part meets the 850 MHz center frequency and 50 Ohm impedance specifications. Ensure compatibility with existing PCB footprints and soldering profiles. Check for any changes in electrical performance metrics such as insertion loss or rejection bandwidth.
