It utilizes a 4-SMD, No Lead package configuration suitable for automated assembly processes. The component exhibits a load capacitance specification of 9 pF and an equivalent series resistance (ESR) of 70 Ohms. Frequency tolerance is rated at ±50 ppm, with a temperature stability range spanning from -10°C to +70°C. This device serves as a precision timing element for digital circuits requiring stable clock signals within specified environmental constraints.

Crystals Feature Summary

• Surface-mount design utilizing a leadless four-terminal package structure
• Fundamental mode operation at 19.2 MHz with 9 pF load capacitance
• Temperature stability covering industrial range from -10°C to +70°C

Crystals Applications

• Precision timing circuits in compact electronic devices
• Clock signal generation for microcontrollers and processors
• Communication modules requiring stable frequency references

Crystals Procurement Notes

Verify the specific datasheet version prior to ordering, as frequency tolerance specifications may vary between ±30 ppm and ±50 ppm depending on the exact manufacturing batch or sub-series designation. Confirm the package type matches the footprint requirements of the target PCB layout. Ensure that the operating temperature range aligns with the environmental conditions of the final application to guarantee long-term reliability and frequency stability under thermal stress.

Crystals Selection Notes

Select this component when a 19.2 MHz reference is required in a small form factor. The 4-SMD no-lead package offers advantages for high-volume surface mount technology assembly lines. Consider the ±50 ppm tolerance against system clock accuracy requirements. Evaluate the ESR of 70 Ohms against oscillator circuit drive level limitations to prevent over-driving the crystal. Ensure the -10°C to +70°C range meets the operational environment needs.

Crystals Part Context

This part belongs to the SXT3249 series of MHz crystal resonators from Suntsu Electronics. The series includes variants with different frequencies and tolerances, such as 13.0 MHz and 13.560 MHz options. The SXT3249BA17-19.200M specifically targets applications needing a standard 19.2 MHz clock source in a compact surface-mount format, distinguishing it from through-hole or larger package alternatives within the broader product portfolio.

Crystals Replacement Considerations

Direct substitutes include other 19.2 MHz crystals with identical 4-SMD no-lead footprints and compatible electrical parameters. Verify that replacement parts match the 9 pF load capacitance and similar ESR values to ensure oscillator circuit compatibility. Cross-reference pinout configurations if available, though leadless packages typically rely on symmetric pad layouts.
