Crystals Procurement Notes

Verify the manufacturer part number against official CTS documentation to ensure authenticity. Confirm that the specific suffix matches the required frequency and tolerance specifications. Check RoHS compliance status if restricted substances are prohibited in your manufacturing process. Ensure the ordering quantity aligns with standard packaging configurations provided by authorized distributors to avoid partial reel issues.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with tight ±10 ppm stability. The 10 pF load capacitance must match the oscillator circuit design parameters. Consider the 60 Ohm ESR value for impedance matching requirements. Verify that the -20°C to +70°C operating range meets the environmental conditions of the target application. The 4-SMD footprint requires compatible stencil design and reflow profiles.
