Crystals Procurement Notes

Verify the specific model suffix against official CTS documentation to confirm exact tolerance and stability ratings. Ensure the application circuit matches the specified 10 pF load capacitance. Confirm that the operating temperature range of -20°C to +70°C meets system requirements. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement.

Crystals Selection Notes

Select this component when a compact SMD quartz crystal is required for 20 MHz applications. Consider the ±30 ppm tolerance and ±50 ppm stability limits relative to system timing accuracy needs. Evaluate the 60 Ohm ESR against oscillator circuit design constraints. Ensure the ceramic package size fits within the available PCB footprint area.

Crystals Part Context

This part belongs to the CTS Model 405 series, which utilizes a ceramic package to reduce size compared to traditional metal cans. The series is engineered for reliability in demanding environments, offering consistent performance in wireless communications.
