Crystals Procurement Notes

Verify the specific tolerance grade required, as datasheets indicate availability in ±5ppm, ±10ppm, and ±20ppm variants. Confirm the operating temperature range matches application needs, typically -20°C to +70°C or -40°C to +85°C. Ensure the 12.5 pF load capacitance aligns with the host circuit design specifications before ordering.

Crystals Selection Notes

Select this component for low-frequency timing applications requiring a through-hole cylindrical form factor. The high ESR characteristic suits low-power oscillator designs. Verify that the host circuit can sustain oscillation with the specified 1 micro watt maximum drive level to prevent frequency drift or damage.
