QT1M-32.768KDZF-T

Overview

The QT1M-32.768KDZF-T is a surface-mount quartz crystal resonator manufactured by QST. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 12.5 pF and a frequency tolerance of ±20 ppm at 25°C. The component features a 2-SMD, no-lead package with dimensions of 6.9 x 1.4 mm. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Surface-mount design for automated assembly
• Quartz crystal construction for stable oscillation
• Standard 32.768 kHz frequency output

Applications

• Real-time clock circuits in embedded systems
• Microcontroller system timing references
• Low-frequency oscillator applications

Procurement Notes

Verify the manufacturer designation matches QST specifications rather than generic equivalents. Confirm the package footprint aligns with 6.9x1.4mm SMD requirements. Ensure the load capacitance specification meets the target circuit design needs before integration.

Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping or low-speed synchronization. Consider the ±20 ppm tolerance sufficient for standard RTC applications. Evaluate thermal stability requirements against the -40°C to +85°C operational range.

Part Context

This crystal belongs to the QT1M series of surface-mount quartz resonators. It serves as a passive frequency control element within electronic assemblies. The part provides a stable reference signal for digital logic circuits requiring accurate time division or clock generation.

Replacement Considerations

Substitute parts must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 6.9x1.4mm footprint. Verify equivalent frequency tolerance and temperature range specifications to ensure circuit compatibility.
