Crystals Procurement Notes

Verify the specific suffix 'CAR' against the manufacturer's current datasheet to confirm packaging type and availability status. Ensure the design-in load capacitance matches the component's 10pF specification to maintain frequency accuracy. Cross-reference the ESR value of 100 Ohms with the oscillator circuit requirements to guarantee reliable startup conditions.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with ±10 ppm stability is required for space-constrained designs. The 4-SMD footprint offers a balance between thermal performance and board real estate. Consider the -20°C to +70°C operating range to ensure suitability for standard commercial environments without requiring extended industrial grade specifications.

Crystals Part Context

This part belongs to the CTS 402 series of general-purpose SMD crystals. The series is characterized by small footprints and standardized pin configurations, facilitating easy integration into various consumer electronics and industrial control boards. The 402 series provides a cost-effective solution for basic timing applications where high-frequency stability is not the primary constraint.

Crystals Replacement Considerations

Publicly documented parameter-equivalent substitutes include 402F27011CKT and 402F27011CJR from CTS-Frequency Controls. Verify that any replacement maintains the same 10pF load capacitance and 100 Ohm ESR to ensure circuit compatibility.
