Crystals Procurement Notes

Verify the exact package dimensions and soldering profile against the official CTS datasheet before finalizing the PCB layout. Ensure that the design load capacitance matches the specified 18 pF to maintain the stated ±10 ppm accuracy. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Crystals Selection Notes

Select this component when a 40 MHz fundamental mode crystal is required with tight frequency stability. Compare ESR values against the oscillator circuit requirements to ensure proper startup conditions. Consider the 4-SMD form factor for space-constrained boards where traditional HC-49 packages are unsuitable.

Crystals Part Context

This part belongs to the CTS 402F series of surface-mount crystals, which are designed for general-purpose frequency control. The series offers various frequencies and tolerances, with the 402F40012IDT specifically targeting applications needing 40 MHz output with enhanced stability compared to standard commercial grade parts.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, ±10 ppm tolerance, 18 pF load capacitance, and 4-SMD no-lead package. Verify pin compatibility and mounting dimensions to ensure mechanical interchangeability without redesigning the footprint.
