3438T-32.768DTN09LLK

Crystals Overview

The 3438T-32.768DTN09LLK is a through-hole quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 32.768 kHz, suitable for precise timekeeping applications. The component features a load capacitance of 7 pF and maintains a frequency tolerance of ±20 ppm across its operational range. It exhibits an equivalent series resistance (ESR) of 30 kΩ and utilizes a cylindrical can package with radial mounting configuration. The physical dimensions are specified as 8 mm in length and 8.2 mm in height, ensuring compatibility with standard PCB layouts requiring axial or radial leaded components.

Crystals Feature Summary

• Through-hole cylindrical can construction with radial leads
• Fundamental mode operation at 32.768 kHz
• Low power consumption characteristics suitable for battery-backed systems

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Wearable device synchronization modules

Crystals Procurement Notes

Verify the specific ordering suffix DTN09LLK against official Suzhou Hangjing documentation to confirm the exact load capacitance and ESR values. Ensure that the through-hole radial package dimensions align with the target PCB footprint. Confirm compliance with RoHS directives if required by the end application. Cross-reference the manufacturer's latest datasheet for any updates on material composition or testing standards prior to final procurement approval.

Crystals Selection Notes

Select this component when a low-cost, through-hole solution is required for 32.768 kHz timing. The 7 pF load capacitance must match the oscillator circuit design requirements. Consider the 30 kΩ ESR limit to ensure reliable oscillation startup within the host circuit. The cylindrical can package offers mechanical stability but requires adequate clearance for the 8.2 mm height profile during assembly.

Crystals Part Context

This part belongs to the general quartz crystal product line of Suzhou Hangjing Elec&Tech Co., Ltd., established in 2014. The company specializes in quartz frequency control units including crystals, oscillators, and filters. This specific model represents a standard frequency option commonly used in digital timekeeping applications, distinct from their surface-mount or temperature-compensated oscillator series.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Users should consult the manufacturer directly for cross-reference information or verify pin-compatible alternatives based on identical electrical parameters such as 32.768 kHz frequency, 7 pF load capacitance, and radial through-hole packaging.
