SXT3247AA38-25.000M

Crystals Overview

The SXT3247AA38-25.000M is a surface-mount crystal oscillator from the Suntsu SXT324 series, featuring a 3.2mm x 2.5mm ceramic package with four solder pads. It operates at a fundamental frequency of 25 MHz with a ±50 ppm frequency tolerance and ±50 ppm stability over the industrial temperature range of -40°C to +85°C. The component utilizes an AT-cut resonator design and includes a dedicated ground pad for enhanced electromagnetic interference resistance. Electrical specifications include a load capacitance of 7 pF and a parallel resonant impedance of 50 Ohms.

Crystals Procurement Notes

Verify the specific ordering suffix against official Suntsu documentation to confirm exact electrical parameters. Ensure the selected variant matches the required load capacitance and temperature grade for the target application environment. Cross-reference the part number with the manufacturer's latest datasheet to validate current production status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor with superior noise immunity is required. The four-pad configuration offers better grounding than standard two-pad designs. Confirm that the 7 pF load capacitance aligns with the host circuit's oscillator requirements. Validate that the ±50 ppm stability meets the system's timing accuracy constraints within the specified industrial temperature window.

Crystals Part Context

This model belongs to the SXT324 series, which provides industrial-grade quartz crystals in a compact 3225 footprint. The series is designed for applications demanding high reliability and precise frequency control in space-constrained environments. The specific suffix indicates the load capacitance, frequency tolerance, and operating temperature range defined by the manufacturer's coding system.

Crystals Replacement Considerations

Direct substitutes must match the 3.2x2.5mm package, 25 MHz frequency, 7 pF load capacitance, and -40 to +85°C temperature range. Verify pin compatibility and equivalent stability ratings. Consult the manufacturer's official replacement guide for validated cross-references.
