SXT2148BA17-25.000M

Crystals Overview

The SXT2148BA17-25.000M is a surface-mount ceramic crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 25 MHz with a load capacitance of 8 pF. The component exhibits a frequency stability of ±30 ppm and a frequency tolerance of ±30 ppm. Its equivalent series resistance (ESR) is specified at 120 Ohms maximum. The device utilizes fundamental mode operation and is housed in a compact 4-SMD, No Lead package measuring 2.0mm x 1.6mm. It supports a commercial operating temperature range of -20°C to +70°C.

Crystals Feature Summary

• Compact 2.0mm x 1.6mm 4-pad surface mount footprint for space-constrained designs
• Fundamental mode operation ensuring reliable oscillation without overtone circuitry
• Ceramic construction providing mechanical robustness and stable electrical performance

Crystals Applications

• Bluetooth audio modules requiring precise clock timing
• Portable consumer electronics with limited PCB area
• General-purpose microcontroller clock sources

Crystals Procurement Notes

Verify the specific suffix 'BA17' corresponds to the required ±30ppm stability and -20°C to +70°C temperature range. Confirm that the 8pF load capacitance matches the host circuit design requirements. Ensure the 120 Ohm ESR specification is compatible with the oscillator circuit's drive level constraints. Check RoHS compliance status if environmental regulations apply to the final assembly.

Crystals Selection Notes

Select this component when a small form factor is critical but standard 2520 packages are too large. The 8pF load capacitance suits circuits designed for lower capacitive loads compared to 18pF variants. The ±30ppm stability is adequate for general digital logic clocks but may be insufficient for high-precision communication interfaces requiring tighter tolerances. Consider higher stability grades if the application demands stricter frequency accuracy over temperature variations.

Crystals Part Context

This part belongs to the SXT214 series of miniature ceramic crystals from Suntsu Electronics. The series is characterized by its reduced physical dimensions, specifically the 2.0mm x 1.6mm package size, which offers approximately 50% less board space usage than traditional 2520 crystals. The series supports various frequencies and stability options, catering to diverse consumer and industrial electronic applications.

Crystals Replacement Considerations

Direct substitutes include other 25MHz, 8pF, 4-SMD crystals with similar ESR and stability ratings. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with other manufacturers offering 2.0x1.6mm ceramic crystals.
