Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against your circuit design before procurement. Confirm that the 4-SOJ package footprint matches your PCB layout constraints. Ensure the ±20 ppm tolerance meets your system's timing accuracy needs. Check for any specific handling instructions regarding surface-mount components during assembly processes.

Crystals Selection Notes

Select this component when a 12 MHz surface-mount crystal is required with moderate stability. Consider the 4-SOJ package size relative to available board space. Evaluate if the 50 Ohm ESR aligns with your oscillator circuit's drive level specifications. Compare against other frequencies in the SXT144 series if alternative timing speeds are needed.

Crystals Part Context

This part belongs to the SXT144 series from Suntsu Electronics, which provides high-frequency crystal solutions. The series offers various frequency options and tolerances, allowing engineers to optimize designs for specific performance requirements. The SXT144 series serves as a replacement for discontinued high-frequency crystals, maintaining similar pad sizes for easier integration.

Crystals Replacement Considerations
