Crystals Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature range (-40°C to +85°C) against your design requirements. Ensure the PCB land pattern matches the 6.00mm x 3.50mm 4-SMD no-lead outline. Confirm that the 20pF load capacitance aligns with the oscillator circuit design to maintain the specified ±30 ppm tolerance. Check RoHS compliance status if required by your assembly standards.

Crystals Selection Notes

Select this component when a 14.31818 MHz fundamental frequency is required for digital logic or communication interfaces. The industrial temperature range makes it suitable for harsher environments compared to commercial variants. Consider the 60 Ohm ESR value for oscillator circuit stability. The 4-SMD package offers space efficiency for dense board layouts while maintaining reliable solder joint integrity during thermal cycling.

Crystals Part Context
