Crystals Procurement Notes

Verify the specific manufacturer part number against official CTS documentation to ensure accuracy, as datasheet listings may vary or indicate discontinuation status. Confirm that the required load capacitance matches the target circuit design specifications before procurement. Check current availability status through authorized distributors, as supply chain fluctuations may affect lead times. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with ±10 ppm stability is required for space-constrained designs. The 10 pF load capacitance must align with the oscillator circuit's input and output capacitance values. Consider the 60 Ohm ESR limit to ensure reliable oscillation startup within the host system. Evaluate the 4-SMD footprint against available PCB real estate and thermal management needs.

Crystals Part Context

This component belongs to the CTS 402 Series of surface-mount crystals, which covers a frequency range from 16 MHz to 60 MHz. The series utilizes standard 4-SMD no-lead packages to facilitate automated assembly processes. These components are designed for general-purpose timing applications requiring moderate stability and small form factors.
