• Microcontroller system clock sources
• Low-power wearable device timing modules

Crystals Procurement Notes

Verify the specific suffix '3215E' against the manufacturer's official datasheet to confirm package dimensions and electrical characteristics. Ensure the load capacitance requirement of 12.5pF matches the target circuit design. Confirm that the ±20ppm frequency tolerance meets the application's precision requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor SMD crystal is required for 32.768 kHz applications. The 12.5pF load capacitance must align with the oscillator circuit's external capacitors. Consider the 70kOhm ESR limit to ensure reliable startup conditions within the host system's oscillator design constraints.

Crystals Part Context

This part belongs to YIC's line of surface-mount quartz crystals. It serves as a timekeeping reference element, distinct from active oscillators by requiring an external oscillator circuit. The 32.768 kHz frequency is standard for binary division to one-second intervals in digital clocks and timers.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with identical 3.2x1.5mm footprints and 12.5pF load capacitance. Verify that replacement parts meet the same ±20ppm tolerance and ≤70kOhm ESR specifications to maintain circuit performance.
