Crystals Procurement Notes

Verify the specific frequency tolerance requirement of ±10ppm against your system design specifications before procurement. Confirm that the 8pF load capacitance matches your oscillator circuit design to ensure accurate frequency performance. Check the operating temperature range limits (-20°C to 70°C) to ensure suitability for your intended environment. Ensure surface mount compatibility with your PCB footprint and reflow soldering profiles.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental mode crystal is required with tight ±10ppm stability. Consider the 4-SMD 2x1.6mm package size for space-constrained designs. Evaluate the 100 Ohm ESR against your oscillator driver strength requirements. Compare against other 402 series variants if different load capacitances or tolerances are needed. Ensure the -20°C to 70°C temperature range covers your application's operational conditions.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals, which are known for providing reliable frequency control solutions. The series offers various frequency options and package styles to support diverse electronic design needs. CTS-Frequency Controls manufactures these components to meet industry standards for quality and consistency in timing applications.

Crystals Replacement Considerations

Direct substitutes within the same series include parts like 402F2041XIAR, though it specifies a 10pF load capacitance instead of 8pF. Verify circuit compatibility when swapping between different load capacitance values. Other 20.48 MHz crystals from CTS may require checking package dimensions and ESR specifications for direct interchangeability.
