Crystals Procurement Notes

Verify the specific suffix 'IDR' against official CTS documentation to confirm the -20°C to +70°C temperature rating and 18pF load capacitance. Ensure the ordering part number matches the required frequency stability of ±10 ppm. Cross-reference datasheets to confirm package dimensions and ESR specifications before procurement.

Crystals Selection Notes

Select this component when a compact SMD crystal is required for 37.4 MHz applications with moderate temperature stability. The integrated thermistor feature aids in thermal management and space-constrained designs. Compare against standard crystals if wider temperature ranges or different load capacitances are needed for the target application environment.

Crystals Part Context

This component belongs to the CTS TSX Crystal series, which integrates a thermistor directly into the crystal unit. This design approach optimizes space within circuit boards by combining frequency control and thermal sensing functions. The series targets automotive, industrial, medical, and military/aerospace markets requiring robust performance.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 402F374XXCDR variants with matching electrical characteristics. Verify that any replacement maintains the same 18pF load capacitance and ±10 ppm stability. Ensure the substitute supports the required -20°C to +70°C operating range.
