Crystals Procurement Notes

Verify the specific suffix 'CLR' against the manufacturer's current datasheet to confirm package dimensions and termination compatibility. Ensure the selected variant matches the required load capacitance and ESR specifications for the target oscillator circuit design prior to final procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal with ±30 ppm stability is required for surface mount assembly. Consider the 12 pF load capacitance requirement for circuit matching. Evaluate the 100 Ohm ESR against the oscillator amplifier drive level constraints to prevent over-driving the crystal element.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and packages optimized for high-volume manufacturing. The 402F20033CLR specifically addresses standard 20 MHz timing needs in a small footprint suitable for dense PCB layouts.
