XTL741-S999-575

Crystals Overview

The Siward XTL741-S999-575 is a passive surface-mount quartz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 32.768 kHz, making it suitable for clock generation in low-power digital circuits. The component features a load capacitance of 12.5 pF and a frequency tolerance of ±20 ppm to ensure stable oscillation. It utilizes a 2-SMD, No Lead package configuration with dimensions of 2.0mm x 1.2mm, optimizing space efficiency on printed circuit boards.

Crystals Feature Summary

• Compact 2.0mm x 1.2mm surface-mount footprint for space-constrained designs
• High stability with ±20 ppm frequency tolerance for accurate timekeeping
• Optimized for low power consumption in portable electronic devices

Crystals Applications

• Real-time clock (RTC) modules in mobile devices

Crystals Procurement Notes

Verify the specific suffix code against official datasheets to confirm exact electrical parameters such as load capacitance and tolerance. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm that the 2-SMD package matches the PCB land pattern requirements for reliable assembly.

Crystals Selection Notes

Select this component when a small form factor is critical alongside standard 32.768 kHz operation. Consider the ±20 ppm tolerance for general-purpose timing where high-precision temperature compensation is not required. Evaluate the 12.5 pF load capacitance against the oscillator circuit design to prevent frequency deviation.

Crystals Part Context

This part belongs to the XTL74 series of thin-type crystals from Siward. The series is characterized by its ultra-small size and high reliability, targeting applications in mobile communications and wireless devices. It represents a specialized solution for clock generation within the broader portfolio of quartz frequency control components.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with identical 2.0x1.2mm footprints and 12.5 pF load capacitance. Verify mechanical dimensions and mounting pad layouts before swapping manufacturers to ensure physical compatibility.
