Crystals Procurement Notes

Verify the specific suffix 'CJR' against official CTS documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design. Cross-reference the part number with current manufacturer availability status, as distribution channels may list discontinued or obsolete inventory that requires careful validation before integration into production schedules.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required within a compact SMD footprint. Verify that the system load capacitance aligns with the specified 9 pF to maintain accuracy. Consider the ±30 ppm stability requirement relative to the application's timing sensitivity. Confirm that the operating temperature range of -20°C to 70°C meets the environmental conditions of the final product deployment.
