3437S-32.768NDT09LLK

Crystals Overview

The 3437S-32.768NDT09LLK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 32.768 kHz, which is standard for real-time clock applications. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 65 kOhms. It utilizes a cylindrical can package with radial leads, suitable for through-hole mounting on printed circuit boards.

Crystals Feature Summary

• Provides stable frequency generation at 32.768 kHz for timekeeping circuits
• Utilizes a cylindrical can package with radial configuration for board integration
• Designed with specific load capacitance characteristics for oscillator compatibility

Crystals Applications

• Real-time clock modules in consumer electronics
• Microcontroller system timing references
• Wearable device power management units

Crystals Procurement Notes

Verify the exact load capacitance specification of 9 pF against your oscillator circuit design requirements. Confirm that the radial leaded package format aligns with your PCB footprint constraints. Ensure the ESR value of 65 kOhms is compatible with the driving capability of your target microcontroller or clock chip to guarantee reliable startup and sustained oscillation.

Crystals Selection Notes

Select this component when a radial leaded form factor is required for 32.768 kHz timing. Consider the 9 pF load capacitance requirement carefully to match the oscillator circuit's total stray capacitance. This part is appropriate for applications where space allows for cylindrical cans and where high-frequency stability is needed for accurate time measurement.

Crystals Part Context

This model belongs to the 3437S series of quartz crystals from Suzhou Hangjing. The series includes variants with different load capacitances and packages, such as SMD options like the NDT06LLK. The 3437S designation indicates a specific cylindrical can construction optimized for low-power, low-frequency applications common in portable devices.

Crystals Replacement Considerations

Cross-reference with other 32.768 kHz radial crystals having 9 pF load capacitance. Verify pin pitch and can dimensions for mechanical fit. Check if alternative manufacturers offer identical electrical parameters including the 65 kOhm ESR limit.
