Crystals Procurement Notes

Verify the specific suffix 'KR' against official CTS documentation to confirm tape-and-reel packaging specifications. Confirm that the ±10 ppm tolerance aligns with system timing requirements. Check current availability status as distribution channels may list discontinued or backorder statuses. Ensure compatibility with the target load capacitance of 8 pF in the final circuit design.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with high stability is required for space-constrained designs. The 4-SMD package suits applications needing low profile and reliable surface mounting. Consider the ±10 ppm tolerance for precision timing needs. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare ESR limits with oscillator circuit capabilities.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals, designed for general-purpose timing applications. The series offers various frequency options and package sizes. The 402F2001XIKR specifically targets cost-sensitive, high-volume consumer electronics. It provides a balance between performance and physical footprint.
