• Surface-mount 4-pin no-lead package design
• Standard 12pF load capacitance specification

Crystals Applications

• Microcontroller clock circuits
• Communication module timing references
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific frequency tolerance and ESR values against the official Suntsu Electronics datasheet for the exact part number. Confirm that the 4-SMD no-lead package dimensions match the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end product specifications.

Crystals Selection Notes

Select this component when a 20 MHz reference with ±15ppm stability is required in a small form factor. The 200 Ohm ESR suits standard oscillator circuits without excessive loading. Consider the 12pF load capacitance compatibility with the host circuit's internal or external capacitors to ensure accurate frequency generation.

Crystals Part Context

This part belongs to the SXT21412ED16 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options within the same physical package, allowing for design flexibility while maintaining consistent board space utilization and assembly parameters across different product variants.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12pF load capacitance, 200 Ohm ESR, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
