• PCMCIA interface devices

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact load capacitance and temperature range specifications. Ensure compatibility with automated pick-and-place equipment due to the 4-SMD no-lead package format. Confirm RoHS compliance status through the manufacturer's current certification records before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a compact 3225 footprint alongside enhanced grounding capabilities. The four-pad configuration offers superior noise immunity compared to standard two-pad variants. Consider the ±30 ppm tolerance and -30°C to +85°C operating range to ensure reliability in demanding industrial environments where thermal fluctuations are common.

Crystals Part Context

This part belongs to the SXT324 series, which represents Suntsu's line of small-form-factor ceramic packaged crystals. The series utilizes AT-cut resonators for stable oscillation. The specific model integrates a 20 pF load capacitance requirement, making it suitable for microcontrollers and processors expecting this standard capacitive load without external adjustment components.

Crystals Replacement Considerations

Direct substitutes must match the 3225 dimensions, 4-pad ground structure, 25 MHz frequency, 20 pF load capacitance, and -30°C to +85°C temperature range. Verify that alternative manufacturers offer equivalent series resistance and holdover characteristics to maintain system timing accuracy.
