SXT21419DA48-50.000M

Crystals Overview

The SXT21419DA48-50.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 50 MHz with a load capacitance of 19 pF. The component exhibits a frequency stability of ±20 ppm and a frequency tolerance of ±20 ppm. Its equivalent series resistance (ESR) is specified as 60 Ohms. The device is housed in a 4-SMD, no-lead package and supports base harmonic operation mode.

Crystals Feature Summary

• Surface-mount design for automated assembly
• Fundamental oscillation mode operation
• Lead-free and RoHS compliant construction

Crystals Applications

• General-purpose clock generation circuits
• Microcontroller system timing references
• Digital signal processing interfaces

Crystals Procurement Notes

Verify the specific suffix DA48 against official Suntsu documentation to confirm exact stability and tolerance ratings. Ensure the 4-SMD footprint matches the target PCB layout. Confirm RoHS compliance status through current manufacturer declarations rather than distributor summaries.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with 19 pF load capacitance is required. The ±20 ppm stability suits applications needing precise timing without oven-controlled accuracy. Evaluate the 60 Ohm ESR against the oscillator circuit requirements to ensure reliable startup.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packaging options. The DA48 suffix indicates specific performance characteristics within this family, distinguishing it from other variants like BA07 or CB27 which may differ in stability or temperature range.

Crystals Replacement Considerations

Direct substitutes include SXT21419BA07-50.000M and SXT21419CA07-50.000M. Verify that alternative suffixes meet the required ±20 ppm stability and 60 Ohm ESR specifications before substitution.
