Crystals Procurement Notes

Verify the specific suffix 'C' against the official CTS datasheet to confirm the exact electrical parameters and package dimensions. Ensure the target circuit design accommodates the specified 18 pF load capacitance and 60 Ohm ESR requirements. Confirm RoHS3 compliance status matches current regulatory standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required in a compact SMD form factor. The 18 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the ±30 ppm tolerance for general timing needs rather than high-precision reference applications requiring tighter stability margins.

Crystals Part Context

This part belongs to the CTS 403 Series, which focuses on small-footprint surface-mount crystals. The series offers various frequencies and packages optimized for space-constrained electronic designs. The 403C35D20M00000 specifically addresses the need for reliable 20 MHz timing in standard industrial temperature ranges.
