Crystals Procurement Notes

Verify the specific suffix 'IAT' against the manufacturer's current datasheet to confirm availability status and packaging configuration. Ensure that the 10pF load capacitance matches the target circuit design requirements before procurement. Cross-reference the ESR value of 80 Ohms with oscillator driver strength specifications to prevent over-driving or startup failures in the final application.

Crystals Selection Notes

Select this component when a 32 MHz fundamental frequency with high stability (±10ppm) is required. The 10pF load capacitance dictates compatibility with specific oscillator circuits; verify host circuit loading conditions. The 4-SMD form factor is ideal for space-constrained PCB layouts. Consider the 80 Ohm ESR when evaluating drive level sensitivity and long-term frequency aging characteristics relative to alternative crystals with different resistance values.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The 402F32012IAT specifically addresses the common 32 MHz requirement for real-time clocks and microcontrollers, providing a balance of size, stability, and cost-effectiveness within the SMD crystal market segment.

Crystals Replacement Considerations

Direct substitutes include 402F32012IKR and 402F32012ILR from CTS-Frequency Controls.
