Crystals Procurement Notes

Verify the specific suffix ILR against project requirements to ensure compatibility with tape-and-reel handling processes. Confirm that the 100 Ohm ESR aligns with oscillator circuit design constraints. Cross-reference the 12 pF load capacitance with the host system's capacitive loading specifications to guarantee frequency accuracy. Validate RoHS3 status if restricted substance regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±20 ppm tolerance is required. Ensure the PCB layout accommodates the 2.00mm x 1.60mm footprint. Consider the 100 Ohm ESR value for oscillator stability margins. Verify thermal performance within the -40°C to +85°C operational range matches the intended environment.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers frequencies from 16 MHz to 60 MHz. The series offers standard ±20 ppm tolerance and ±30 ppm stability. The 402F25022ILR specifically targets high-volume surface-mount applications requiring reliable timing references in consumer and industrial electronics.
