QT1C-32.768KDZC-T

Overview

The QT1C-32.768KDZC-T is a quartz crystal resonator manufactured by QST Corporation, designed for precision timing applications requiring a nominal frequency of 32.768 kHz. This component features a load capacitance of 9 pF and maintains a frequency tolerance of ±20 ppm at 25°C. It operates within an extended temperature range of -40°C to +85°C, ensuring stability in diverse environmental conditions. The device utilizes a compact 2-SMD, No Lead package with body dimensions measuring 1.6 x 1.0 mm, facilitating surface-mount integration into space-constrained circuit designs.

Feature Summary

• Provides stable oscillation at the standard 32.768 kHz frequency for real-time clock synchronization
• Utilizes a miniature 2-SMD no-lead package for efficient surface-mount assembly
• Maintains specified frequency tolerance across a wide industrial temperature range

Applications

• Real-time clock circuits in portable electronic devices
• Microcontroller system timing references
• Low-power wearable technology modules

Procurement Notes

Verify that the specific suffix KDZC-T matches the required load capacitance and tolerance specifications for your design. Confirm the operating temperature range aligns with your application environment. Ensure the 2-SMD footprint corresponds to your PCB layout constraints. Cross-reference the manufacturer datasheet for mechanical drawing details before finalizing procurement decisions.

Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping functions. Consider the 9 pF load capacitance requirement to ensure proper oscillator circuit tuning. Evaluate the ±20 ppm tolerance against your system's timing accuracy needs. The compact 1.6 x 1.0 mm size makes it suitable for dense board layouts where larger packages are not feasible.

Part Context

This quartz crystal belongs to QST's line of surface-mount resonators intended for low-frequency timing applications. It serves as a critical passive component in digital systems requiring accurate time division or clock generation. The 32.768 kHz frequency is standard for binary-based timekeeping due to its divisibility by powers of two.

Replacement Considerations

Compatible substitutes include other 32.768 kHz SMD crystals with matching 9 pF load capacitance and similar physical dimensions. Verify equivalent tolerance and temperature range specifications before substitution. Check pinout compatibility if alternative manufacturers offer different lead configurations.
