Crystals Procurement Notes

Verify the specific suffix 'ILT' corresponds to the tape-and-reel packaging format required for your manufacturing line. Confirm that the ±10ppm tolerance meets your system's jitter requirements. Ensure the 12pF load capacitance matches your oscillator circuit design. Check current availability status as distribution channels may vary.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with high stability is required in a small form factor. The 100 Ohm ESR value influences oscillator circuit loading; verify compatibility with your host driver. Consider the 4-SMD footprint constraints against available PCB real estate. Evaluate thermal performance within the specified -40°C to 85°C operational window.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and packages optimized for consumer and industrial electronics.
