3438T-32.768DTN07LLK

Crystals Overview

The 3438T-32.768DTN07LLK is a cylindrical can, radial through-hole quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 7 pF and a frequency tolerance of ±20 ppm. The component features a maximum series resistance of 30 kOhms and measures 8 mm in length by 8.2 mm in height.

Crystals Feature Summary

• Radial leaded cylindrical can package for through-hole mounting
• Fundamental mode operation at 32.768 kHz
• Designed for low-power timing applications

Crystals Applications

• Real-time clock circuits
• Microcontroller system clocks
• Wristwatches and portable electronics

Crystals Procurement Notes

Verify the specific load capacitance requirement of 7 pF against the target circuit design to ensure accurate frequency stability. Confirm that the 30 kOhm maximum series resistance aligns with the oscillator driver strength capabilities. Ensure the physical dimensions of 8 mm length and 8.2 mm height fit within the designated PCB footprint constraints.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. The 7 pF load capacitance specification distinguishes it from other variants like the 6 pF version. Consider the ±20 ppm tolerance for general consumer applications where high precision is not critical.

Crystals Part Context

This part belongs to the 3438T series of cylindrical crystals produced by Suzhou Hangjing. The manufacturer specializes in quartz frequency control units including crystals, oscillators, and filters. The company was founded in 2014 and focuses on research, development, and production of these components.

Crystals Replacement Considerations

The 3438T-32.768DTN06LLK is a documented alternative from the same manufacturer offering identical frequency and package but with a 6 pF load capacitance.
