Crystals Procurement Notes

Verify the specific datasheet from Suntsu Electronics to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with reflow soldering profiles defined in the manufacturer's documentation. Cross-reference the DigiKey part number 2388-SAX21412CX4B-40.000M-ND for accurate supply chain tracking.

Crystals Selection Notes

Select this component when a precise 40 MHz reference is required in space-constrained designs. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the 60 Ohm ESR for impedance matching within the host system design constraints.

Crystals Part Context

This part belongs to the SAX series of surface mount crystals from Suntsu Electronics. It shares the 4-SMD no-lead form factor with other variants in the lineup but differs in frequency and specific electrical parameters. The model designation indicates its unique operational specifications within the product family.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 12 pF load capacitance and similar ESR values. Verify pinout compatibility and mechanical dimensions before substitution. Consult official cross-reference lists for approved alternatives.
