Crystals Procurement Notes

Verify that the specific suffix CAR corresponds to the required tape and reel packaging configuration for your production line. Confirm that the 60 Ohm ESR value aligns with the oscillator circuit design specifications to ensure proper startup conditions. Ensure the 10 pF load capacitance matches the host circuit's external capacitor requirements to maintain the specified ±30 ppm frequency accuracy across the operational temperature range.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required within a compact 2.00mm x 1.60mm SMD envelope. The ±30 ppm tolerance suits general-purpose timing applications where high precision is not critical. Consider the 60 Ohm ESR limit when designing the oscillator feedback network. This part is suitable for standard commercial temperature ranges extending from -20°C to +70°C.
