Crystals Procurement Notes

Verify the specific suffix IJR against the manufacturer datasheet to confirm pin configuration and tape/reel specifications. Ensure the target circuit design accommodates the 9pF load capacitance requirement. Check for obsolescence status or end-of-life notifications directly from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 20MHz fundamental crystal with ±10ppm tolerance is required. The 9pF load capacitance must match the oscillator circuit's external capacitor values. Consider the 100 Ohm ESR limit for drive level sensitivity. The 4-SMD package size suits high-density PCB layouts requiring small footprint components.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The 402F20012IJR specifically targets applications needing stable 20MHz timing in a minimal space envelope.

Crystals Replacement Considerations

Direct substitutes include 402F20012ILT and 402F20012IAR. Verify electrical parameters such as load capacitance and ESR match exactly. Package dimensions should be compared to ensure mechanical compatibility within the existing PCB layout constraints.
