Crystals Procurement Notes

Verify the specific suffix 'A' indicates the 10pF load capacitance variant against circuit requirements. Confirm that the 405I series industrial rating meets the operational temperature extremes of the target environment. Ensure the 4-SMD package dimensions align with the PCB land pattern specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental crystal with 10pF load capacitance is required for industrial environments. Compare ESR values against oscillator driver strength limitations. Consider the ±30ppm tolerance relative to system clock accuracy needs. Verify compatibility with existing PCB footprints designed for the 5.00mm x 3.20mm SMD package.

Crystals Part Context

This part belongs to the CTS 405 series of surface-mount crystals. The 'I' suffix denotes industrial temperature performance, while 'A' specifies the 10pF load capacitance configuration. It complements other variants in the series offering different frequencies and load capacitances for diverse design requirements.

Crystals Replacement Considerations

Direct substitutes include 405C35A40M00000 for commercial temperature range applications. Cross-manufacturer equivalents must match the 40MHz frequency, 10pF load capacitance, and 4-SMD package dimensions to ensure mechanical and electrical compatibility.
