Crystals Procurement Notes

Verify the specific ordering suffix IKR against the manufacturer's current datasheet to ensure correct packaging and terminal configuration. Confirm that the 8pF load capacitance matches the target circuit design requirements. Check for any recent lifecycle status updates or obsolescence notices directly from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental crystal with low ESR is required for space-constrained designs. Ensure the application circuit can accommodate the 8pF load capacitance to maintain the specified ±10ppm frequency tolerance. Consider the -40°C to +85°C operating range if the environment exceeds standard commercial limits.
