Crystals Procurement Notes

Verify the specific suffix 'IJT' against official CTS documentation to confirm pinout and marking orientation. Ensure the target circuit design accommodates the 9pF load capacitance and 100 Ohm ESR specifications. Confirm that the -40°C to +85°C temperature range meets the operational requirements of the final assembly environment.

Crystals Selection Notes

Select this component when precise timing accuracy is required within a limited board space. The ±10ppm stability makes it suitable for applications sensitive to clock jitter or phase noise. Compare the 9pF load capacitance against existing circuit designs to ensure proper oscillator loading without additional external capacitors.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series is characterized by small footprint options and reliable performance for general-purpose frequency control. The 402F20412IJT specifically utilizes the 2.00mm x 1.60mm package size, offering a balance between size reduction and electrical performance for modern electronic devices.

Crystals Replacement Considerations

Direct substitutes include parts with identical 20.48 MHz frequency, 9pF load capacitance, and ±10ppm tolerance in the same 4-SMD package. Verify that any replacement maintains the 100 Ohm ESR and -40°C to +85°C operating range to ensure circuit compatibility.
