3426S-32.768DT07LLK

Crystals Overview

The 3426S-32.768DT07LLK is a cylindrical can, radial leaded quartz crystal manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 7 pF and an equivalent series resistance of 40 kOhms. The component features a tolerance of ±20 ppm and utilizes a tuning fork oscillator design. This through-hole device is packaged in a standard cylindrical can format suitable for radial mounting on printed circuit boards.

Crystals Feature Summary

• Tuning fork oscillator design optimized for low-power timing applications
• Cylindrical can package with radial leads for through-hole mounting
• Stable frequency generation for real-time clock circuits

Crystals Applications

• Real-time clock (RTC) circuits
• Wristwatch timing modules
• Low-power consumer electronics

Crystals Procurement Notes

Verify the specific manufacturer datasheet for precise electrical characteristics and mechanical dimensions before integration. Confirm that the radial lead configuration matches the target PCB footprint requirements. Ensure the load capacitance specification aligns with the host oscillator circuit design to maintain accuracy within the stated tolerance limits.

Crystals Selection Notes

Select this component when a through-hole, radial leaded crystal is required for 32.768 kHz timing. The 7 pF load capacitance and 40 kOhm ESR are critical parameters for circuit compatibility. Consider the ±20 ppm tolerance against application stability needs. Verify availability of the specific suffix DT07LLK for packaging and material compliance requirements.

Crystals Part Context

This part belongs to the 3426S series of cylindrical crystals from Suzhou Hangjing. The series covers various frequencies including 32.768 kHz and ranges from 28-80 kHz. The company specializes in quartz frequency control units, producing components for industrial and consumer markets since its founding in 2014.

Crystals Replacement Considerations

The 3426T-32.768DT07LLK is a tape and reel variant of the same electrical specifications but with surface mount packaging. Direct substitution requires PCB layout changes. Other manufacturers' 32.768 kHz crystals must match the 7 pF load capacitance and 40 kOhm ESR values.
