Crystals Applications

• Real-time clock modules
• Watch movement circuits
• Medical monitoring devices

Crystals Procurement Notes

Verify the specific ordering suffix and exact datasheet revision before procurement, as specifications may vary by production batch. Confirm that the 2-SMD, No Lead package dimensions match the target PCB footprint. Ensure compliance with Class III life-supporting device requirements if used in safety-critical systems. Request official documentation from Geyer Electronic America, Inc. to validate electrical parameters against design constraints.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for low-power digital timing applications. The 12.5 pF load capacitance must align with the oscillator circuit design to ensure accurate frequency generation. Consider the -10 ppm to +22 ppm tolerance if long-term drift is acceptable for the application. The surface-mount form factor is suitable for compact electronic assemblies where space efficiency is prioritized over through-hole mounting.
