Crystals Procurement Notes

Verify the specific suffix 'IAR' against manufacturer documentation to confirm packaging configuration and compliance status. Cross-reference the detailed description parameters, including 10pF load capacitance and 60 Ohm ESR, with circuit design requirements. Ensure compatibility with reflow soldering profiles for 4-SMD packages. Confirm availability status as distribution listings may vary.

Crystals Selection Notes

Select this component when a 40 MHz fundamental crystal with ±20ppm stability is required for space-constrained designs. The 10pF load capacitance must match the oscillator circuit's external capacitor values. Consider the 60 Ohm ESR for drive level sensitivity. The 4-SMD footprint suits high-density PCB layouts where through-hole components are unsuitable.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and package options for general-purpose frequency control. The 402F40022IAR specifically addresses needs for 40 MHz timing in consumer and industrial electronics requiring reliable surface mount solutions.

Crystals Replacement Considerations

Direct substitutes include 402F40022IJT and 402F40022IKR from the same manufacturer, provided load capacitance and package dimensions align with design constraints. Verify that alternative parts maintain identical 40 MHz frequency and ±20ppm stability specifications.
