The SXT22412AA27-12.288M is a surface-mount MHz crystal manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 12.288 MHz with a frequency stability of ±50ppm and a load capacitance of 12pF. The component features an equivalent series resistance (ESR) of 120 Ohms and utilizes a base resonator type. It is housed in a 4-SMD, No Lead package suitable for automated assembly processes.

Crystals Feature Summary

• Surface-mount design compatible with standard pick-and-place equipment
• Base resonator crystal technology for stable oscillation
• Defined load capacitance for precise circuit integration

Crystals Applications

• Digital signal processing clock sources
• Microcontroller system timing references
• Communication interface synchronization circuits

Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as conflicting data exists between 60 Ohms and 120 Ohms in available sources. Confirm the exact frequency tolerance specification prior to ordering. Ensure the 4-SMD package dimensions match the target PCB footprint requirements. Request manufacturer documentation to validate performance characteristics under operating conditions.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required for digital systems. Consider the ±50ppm stability limit for application temperature ranges. Evaluate the 120 Ohm ESR impact on oscillator circuit loading. Compare against alternative frequencies if system requirements differ from standard serial communication baud rates.
