Crystals Procurement Notes

Verify the exact datasheet specifications directly from Suntsu Electronics to confirm environmental ratings and soldering profiles. Ensure compatibility with the target circuit's load capacitance requirements. Cross-reference the part number suffixes to identify any specific tape-and-reel or bulk packaging variations that may affect handling procedures during assembly.

Crystals Selection Notes

Select this component when a 40 MHz frequency with ±15 ppm stability is required in a small form factor. The 18 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for impedance matching. This part is appropriate for applications where space constraints necessitate a 4-SMD package over through-hole alternatives.

Crystals Part Context

This model belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability options within a standardized footprint. The EA48 suffix typically denotes specific electrical characteristics and temperature ranges associated with this product line, distinguishing it from other variants in the catalog.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 18 pF load capacitance and similar ESR values. Verify pinout compatibility for the 4-SMD package. Check if alternative manufacturers offer components with equal or better stability ratings such as ±15 ppm or tighter tolerances.
