XTL741-U11-402

Crystals Overview

The XTL741-U11-402 is a surface-mount crystal oscillator manufactured by Siward. It operates at a fundamental frequency of 32.768 kHz with a frequency tolerance of 20 ppm. The component utilizes a 2-SMD, no lead package configuration, specifically sized as 2x1.2 mm. It is designed for reliable performance across an operating temperature range of -40°C to 85°C. This device serves as a precision timing element suitable for applications requiring stable low-frequency clock signals in compact electronic designs.

Crystals Feature Summary

• Fundamental mode operation ensures precise frequency generation
• Compact 2-SMD surface mount package facilitates automated assembly
• Wide operating temperature range supports diverse environmental conditions

Crystals Applications

• Real-time clock circuits
• Microcontroller system clocks
• Low-power embedded devices

Crystals Procurement Notes

Verify the exact package dimensions and pin configuration against the official datasheet before integration. Confirm that the 20 ppm tolerance meets the specific timing requirements of the target application. Ensure compatibility with standard reflow soldering profiles for 2-SMD components to maintain device integrity during manufacturing processes.

Crystals Selection Notes

Select this component when a small footprint and fundamental frequency stability are required for timekeeping functions. Consider the 20 ppm tolerance limit for long-term accuracy needs. Evaluate the -40°C to 85°C range against the operational environment of the final product to ensure consistent performance under varying thermal conditions.

Crystals Part Context

This part belongs to Siward's line of surface-mount crystals, designed for cost-effective and space-constrained electronics. The XTL741 series typically targets high-volume consumer and industrial applications where reliable timing is critical but extreme precision beyond 20 ppm is not mandatory. It complements other passive components in power management and control systems.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 20 ppm tolerance, and 2-SMD 2x1.2 mm package. Verify electrical characteristics and mounting specifications with alternative manufacturers to ensure functional equivalence without redesigning the PCB layout.
