Crystals Procurement Notes

Verify current availability status as the component may be subject to discontinuation notices. Confirm that the specific 8 pF load capacitation matches the target oscillator circuit requirements. Ensure the -20°C to +70°C temperature range aligns with the operational environment specifications before finalizing procurement orders.

Crystals Selection Notes

Select this model when a 12 MHz clock source is required within a compact 3225 footprint. The 8 pF load capacitance necessitates verification against the host MCU's internal or external capacitor values. Consider the glass-seal technology if long-term frequency stability under thermal cycling is critical for the application design.

Crystals Part Context
