Crystals Procurement Notes

Verify the specific suffix and manufacturer designation against official CTS documentation to ensure compatibility. Confirm that the 4-SMD footprint matches the target PCB layout. Check current availability status as distribution channels may vary. Ensure environmental compliance requirements such as RoHS are met for the intended application.

Crystals Selection Notes

Select this component when a 12 MHz reference with ±10 ppm tolerance is required. The 4 pF load capacitance must match the oscillator circuit design. Consider the 100 ohm ESR for drive level limitations. The -40°C to +85°C range suits standard industrial environments. Verify package dimensions against board space constraints.
