3111M-32.768DTNTLLLK

Crystals Overview

The 3111M-32.768DTNTLLLK is a surface-mount 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 12.5 pF and a frequency stability of ±20 ppm. The component features an equivalent series resistance (ESR) of 70 kOhms and utilizes a compact 2-SMD, no lead package measuring 1.6x1.0x0.5 mm. Designed for high-reliability applications, it employs a vacuum-sealed ceramic package suitable for high-temperature reflow soldering processes.

Crystals Feature Summary

• Compact 1.6x1.0x0.5 mm SMD footprint with two pads
• High-reliability vacuum-sealed ceramic packaging

Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required load capacitance and stability specifications. Confirm that the ceramic package type matches the thermal requirements of the assembly process. Check RoHS compliance status if environmental regulations apply to the final product. Ensure the ESR value aligns with the oscillator circuit design constraints.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is needed for timekeeping or low-frequency timing applications. The small form factor makes it suitable for space-constrained designs. Consider the ±20 ppm stability requirement against the system's total timing accuracy needs. Verify that the 12.5 pF load capacitance matches the external capacitors used in the oscillator circuit.

Crystals Part Context

This part belongs to the family of quartz crystal resonators produced by Suzhou Hangjing Elec&Tech Co., Ltd., a manufacturer specializing in frequency control units since 2014. The company focuses on research, development, and production of high-precision quartz devices.
