Crystals Procurement Notes

Verify the specific suffix 'A' indicates a 10 pF load capacitance, as this differs from other variants in the 405 series. Confirm the operating temperature range matches the 'C' designation (-20°C to +70°C). Ensure the ESR value of 60 Ohms aligns with the target oscillator circuit design requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a 16.9344 MHz fundamental frequency with 10 pF load capacitance is required. The 405 series offers reduced size compared to traditional crystals. Verify that the 60 Ohm ESR is compatible with the host microcontroller or oscillator IC specifications. Consider the -20°C to +70°C temperature range against the application's environmental constraints.

Crystals Part Context

This part belongs to the CTS 405 Series, which consists of ceramic-packaged crystals designed for reduced size and shock performance. The series is widely used in wireless telecommunications and portable devices. The 405C35A16M93440 specifically denotes the 16.9344 MHz frequency variant within this family, sharing physical dimensions and mounting characteristics with other models in the series.

Crystals Replacement Considerations

Direct substitutes within the same manufacturer series include parts with identical frequency and load capacitance but potentially different tolerances or temperature ranges. Cross-manufacturer replacements must match the 16.9344 MHz frequency, 10 pF load capacitance, 4-SMD footprint, and 60 Ohm ESR specifications.
