Crystals Procurement Notes

Verify the specific suffix code corresponding to the required frequency tolerance and load capacitance configuration before procurement. Confirm that the selected variant matches the target circuit's load requirements. Ensure compatibility with the designated operating temperature range. Cross-reference the manufacturer datasheet for the exact electrical parameters associated with the full part number to avoid specification mismatches during integration.

Crystals Selection Notes

Select this component when a 32 MHz fundamental resonance is required with ±15 ppm stability. The 10 pF load capacitance must align with the oscillator circuit design. Consider the 80 Ohm ESR limit for drive level sensitivity. The 4-SMD package size suits space-constrained PCB layouts. Verify thermal performance against the -20°C to +70°C operational window.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequency codes and package options. The 402F320XXCAT specifically denotes the 32 MHz variant with CAT suffix specifications. It shares mechanical dimensions with other members of the 402 family but differs in electrical characteristics based on the frequency code.

Crystals Replacement Considerations

Direct substitutes include other 402 series variants with matching 32 MHz frequency, 10 pF load capacitance, and ±15 ppm tolerance. Verify pinout compatibility and ESR limits. Alternative packages require re-evaluation of soldering profiles and mechanical clearance.
