Crystals Procurement Notes

Verify the specific suffix 'IAR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 10pF load capacitance matches the target circuit design specifications. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages. Check for any specific handling requirements related to moisture sensitivity level classification during storage and assembly.

Crystals Selection Notes

Select this component when a 32 MHz fundamental frequency with tight ±10 ppm stability is required. The 10pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 80 Ohm ESR limit for drive level sensitivity. The 4-SMD footprint suits space-constrained PCB layouts. Verify thermal performance meets the -40°C to +85°C operational range for the intended environment.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals, which covers frequencies from 16 MHz to 60 MHz. The series is characterized by small form factors and reliable performance for consumer and industrial electronics. The 402F32012IAR specifically targets applications needing precise 32 MHz timing in a minimal footprint, leveraging CTS's manufacturing capabilities for consistent quality and compliance.

Crystals Replacement Considerations

Direct substitutes include other 32 MHz crystals with identical 10pF load capacitance, ±10 ppm tolerance, and 4-SMD (2.0x1.6mm) footprint. Verify ESR compatibility around 80 Ohms. Alternative parts must support the same -40°C to +85°C temperature range. Ensure the replacement maintains fundamental mode operation and RoHS3 compliance for seamless integration.
