Crystals Procurement Notes

Verify the specific suffix 'CJR' against official CTS documentation to confirm packaging configuration and compliance status. Ensure the selected variant matches the required load capacitance and ESR specifications for the target oscillator circuit design before procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±30 ppm stability is required in a small SMD footprint. Consider the 100 Ohm ESR value for oscillator loop gain calculations. Verify that the -20°C to +70°C operating range meets the environmental requirements of the final assembly.

Crystals Part Context

This part belongs to the CTS 402 Series of general-purpose crystals. It utilizes standard AT-cut quartz technology optimized for cost-effective mass production. The 4-SMD form factor allows for automated pick-and-place assembly, supporting high-volume manufacturing processes in consumer electronics.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 9pF load capacitance and similar ESR values from the same manufacturer series. Cross-brand replacements must match the 2.00x1.60mm package dimensions and electrical parameters to ensure circuit compatibility.
