Crystals Procurement Notes

Verify the specific package dimensions and electrical parameters against the official CTS datasheet before integration. Confirm that the 18pF load capacitance matches the target circuit design requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application. Cross-reference the manufacturer part number to avoid confusion with similar variants in the 402 series.

Crystals Selection Notes

Select this component when a compact surface-mount crystal with 38.4 MHz frequency is required. The 18pF load capacitance distinguishes it from other variants like the 402F38411CAR which uses 10pF. Consider the 60 Ohm ESR value for impedance matching in the oscillator circuit. The small footprint suits space-constrained PCB layouts compared to larger packages.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. It shares the same frequency and general specifications as the 402F38411CAR but differs in load capacitance and physical package size. The series offers various frequency options and package styles for diverse electronic design needs.

Crystals Replacement Considerations

The 402F38411CAR is a direct alternative within the same series but features a different load capacitance (10pF vs 18pF) and package size. Verify circuit compatibility regarding load capacitance before substitution. Other 38.4 MHz crystals from different manufacturers may require schematic adjustments.
