Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and tolerance levels. Confirm that the 30 kOhm ESR aligns with the oscillator circuit design requirements. Check manufacturer documentation for operating temperature range limitations. Ensure the through-hole footprint matches the target PCB layout. Validate part status availability directly with authorized distributors.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping functions. The tuning fork architecture provides stable oscillation for low-power applications. Consider the through-hole form factor if surface-mount options are unsuitable. Evaluate the ±10ppm tolerance against system accuracy needs. Verify the ESR value supports the driving circuit impedance.
