Crystals Procurement Notes

Verify the specific suffix CAR against official CTS documentation to confirm the 10pF load capacitance requirement. Ensure the design accommodates the specified 100 Ohm ESR and ±30ppm stability limits. Confirm that the -20°C to +70°C operating range meets the thermal requirements of the target application environment before finalizing the component selection.

Crystals Selection Notes

Select this component when a 27 MHz timing reference with a 10pF load capacitance is required. The 4-SMD package size of 2.00mm x 1.60mm is appropriate for space-constrained PCB layouts. Verify that the circuit oscillator design matches the 100 Ohm ESR specification to ensure reliable startup and sustained oscillation within the industrial temperature range.

Crystals Part Context

This part belongs to the 402 Series of SMD crystals from CTS-Frequency Controls. The series offers various load capacitances and package sizes. The 402F27033CAR specifically denotes the 27 MHz frequency, ±30ppm stability, and 10pF load capacitance variant within this standardized product line.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz SMD crystals with identical 10pF load capacitance and similar ESR values. Cross-reference the pinout and mechanical dimensions of alternative manufacturers' parts to ensure compatibility with the existing footprint.
