Crystals Procurement Notes

Verify the specific suffix CLT against official CTS documentation to confirm the 12pF load capacitance and tape-and-reel packaging configuration. Ensure compatibility with the target circuit's load capacitance requirements before integration. Cross-reference the datasheet for any updates regarding lead times or obsolescence status directly from the manufacturer.

Crystals Selection Notes

Select this component when a 20.48 MHz reference with ±30 ppm stability is required for space-constrained designs. The 12pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for impedance matching. Verify that the operating temperature range of -20°C to +70°C meets the application environment specifications.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and packages optimized for high-volume manufacturing. The 402F20433CLT specifically addresses applications needing precise timing in compact form factors, leveraging standard SMD footprint compatibility for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes include other 20.48 MHz crystals with identical 12pF load capacitance and 4-SMD dimensions. Verify ESR limits and stability tolerances match the original design constraints. Alternative manufacturers may offer pin-compatible parts, but electrical parameter validation is essential.
