Crystals Procurement Notes

Verify the specific suffix CAT against official CTS documentation to confirm tape and reel packaging specifications. Confirm current availability status as supply conditions may vary. Ensure the receiving facility meets MSL Level 1 handling requirements. Cross-reference the 100 Ohm ESR value with circuit design constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz fundamental resonance is required with tight ±10ppm stability. The 10pF load capacitance must match the host oscillator circuit design. Consider the 100 Ohm ESR for drive level limitations. The 4-SMD footprint requires compatible PCB land pattern dimensions of 2.00mm by 1.60mm.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package sizes. The 402F20011CAT specifically addresses the 20 MHz market segment with standard commercial temperature ranges. It serves as a direct replacement for legacy through-hole or larger SMD crystals in space-constrained designs.
