• General-purpose digital circuit timing

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical parameters such as temperature range and tolerance. Ensure the 4-SOJ footprint matches the target PCB layout. Confirm that the 18pF load capacitance aligns with the host circuit requirements to guarantee proper oscillation start-up and stability.

Crystals Selection Notes

Select this component when a 12 MHz frequency is required in a small form factor. The 4-SOJ package offers a balance between size and soldering reliability compared to smaller SMD options. Consider the ±30ppm tolerance if high-precision timing is not critical. Verify that the 50 Ohm ESR is compatible with the oscillator circuit's drive level specifications.

Crystals Part Context

This part belongs to the SXT144 series of plastic-encapsulated crystals from Suntsu Electronics. The series is characterized by its 4-pin SOJ configuration, which facilitates automated assembly. The SXT144 line generally covers frequencies from 3.579 MHz to 27 MHz, offering various load capacitances and tolerance grades for diverse industrial and commercial applications.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 18pF load capacitance, 50 Ohm ESR, and 4-SOJ 9.50mm pitch package. Cross-reference with other manufacturers' 4-SMD crystal offerings ensuring identical mechanical dimensions and electrical characteristics to maintain circuit performance.
