Crystals Procurement Notes

Verify the specific suffix 'ILR' against official CTS documentation to confirm tape and reel packaging specifications. Ensure the required frequency tolerance of ±10 ppm aligns with system design constraints. Cross-reference the 12 pF load capacitance with the host oscillator circuit requirements to guarantee accurate frequency performance.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental crystal with high stability is required in a compact footprint. The 4-SMD form factor suits automated assembly processes. Consider the 120 Ohm ESR value for oscillator drive level compatibility. Verify that the ±10 ppm stability meets the application's timing accuracy needs compared to lower-cost alternatives.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers standard-sized crystals for general-purpose applications. The series provides various frequency options within a consistent 2.0mm x 1.6mm package profile.
