SXT32421CA27-50.000M

Crystals Overview

The SXT32421CA27-50.000M is a 50 MHz ceramic surface-mount crystal manufactured by Suntsu Electronics, Inc. It operates within a temperature range of -10°C to +70°C and features a frequency tolerance and stability of ±25 ppm at 25°C and across the full operating range, respectively. The component utilizes a 21 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 35 Ohms. It is housed in a compact 4-SMD, no-lead package designed for automated surface-mount assembly.

Crystals Feature Summary

• Utilizes a 4-pad ceramic surface-mount construction for enhanced mechanical reliability compared to standard two-terminal designs.
• Provides stable oscillation performance with ±25 ppm frequency tolerance and temperature stability specifications.
• Engineered for direct integration into high-density printed circuit board layouts using standard SMT processes.

Crystals Applications

• Industrial wireless data acquisition modules
• Communication test equipment
• PCMCIA card interfaces
• General-purpose embedded systems requiring precise timing references

Crystals Procurement Notes

Verify that the specific suffix CA27 corresponds to the required -10°C to +70°C temperature range and ±25 ppm stability for your application environment. Confirm that the 35 Ohm ESR limit is compatible with the oscillator circuit's negative resistance margin. Ensure the 4-SMD footprint matches the PCB land pattern design to prevent soldering defects during assembly.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate stability specifications suitable for industrial environments. Consider the 21 pF load capacitance requirement for circuit matching. Evaluate if the -10°C lower temperature limit meets operational needs; otherwise, explore wider temperature variants within the same series family.

Crystals Part Context

This part belongs to the SXT324xx series of ceramic crystals from Suntsu Electronics, characterized by a 3.2mm x 2.5mm footprint. The series offers various load capacitances and stability grades, allowing designers to balance size, cost, and performance requirements for consumer and industrial electronics applications.

Crystals Replacement Considerations

Direct substitutes include the SXT32421CC27-50.000M and SXT32421CB07-50.000M, which share identical electrical parameters but may differ in temperature range or tolerance grading. Verify pin compatibility and thermal characteristics before substitution.
