Crystals Procurement Notes

Verify the specific suffix 'D' against official CTS documentation to confirm the exact load capacitance and tolerance specifications, as ordering codes may vary. Ensure the application circuit matches the 18 pF load requirement to maintain frequency accuracy. Confirm that the operating environment stays within the specified -20°C to +70°C range. Check for any recent product change notices regarding package dimensions or material composition before finalizing procurement.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with ±30 ppm tolerance is required in a compact SMD form factor. The 18 pF load capacitance must align with the oscillator circuit design to prevent frequency deviation. Consider the 50 Ohm ESR value for driving capability requirements. This part is suitable for applications where standard commercial temperature ranges are sufficient and space constraints necessitate a 5.00 mm x 3.20 mm footprint.

Crystals Part Context

This component belongs to the CTS 405 series of surface-mount crystals, designed for general electronic applications. The series offers various frequencies and packages, with the 405C35D50M00000 specifically providing a 50 MHz output in a 4-SMD configuration.
