Crystals Procurement Notes

Verify the specific load capacitance requirement of 18pF against the target circuit design to ensure frequency accuracy. Confirm that the operating temperature range of -20°C to +70°C aligns with the intended application environment. Check current availability status as supply chain conditions may vary. Ensure compliance with RoHS3 directives if required by project specifications. Validate package dimensions for PCB footprint compatibility prior to procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental mode crystal is required for surface mount designs. The ±10ppm tolerance suits applications demanding higher precision than standard ±15ppm parts. Consider the 18pF load capacitance requirement for oscillator circuit tuning. The 4-SMD package offers space efficiency for dense layouts. Evaluate thermal constraints against the specified -20°C to +70°C operational range.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series provides various frequencies and package options for timing applications. The 402F27111CDR specifically addresses needs for 27.12 MHz generation in compact electronic devices. It complements other variants in the lineup offering different tolerances and load capacitances.

Crystals Replacement Considerations

Direct substitutes within the same series include 402F271XXCKT, though it specifies 18pF load capacitance and ±15ppm tolerance rather than ±10ppm. Verify functional equivalence regarding frequency stability and electrical parameters before substitution. Cross-reference package dimensions to ensure mechanical compatibility.
