Crystals Procurement Notes

Verify the specific suffix 'IMR' against the manufacturer's current datasheet to confirm packaging and material specifications. Ensure the design-in process accounts for the 4pF load capacitance requirements of the target circuit. Check for alternative lead-free options if environmental compliance standards have changed since the original product release.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with tight ±10 ppm tolerance is required. The low ESR of 80 Ohms suits high-speed digital loads. Consider the 4pF load capacitance compatibility with the host oscillator circuit. The wide temperature range makes it suitable for industrial environments where thermal stability is critical for timing accuracy.

Crystals Part Context

This part belongs to the 402W series of surface mount crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for space-constrained designs.
