3131M-32.768DTTLLL-R50K

Crystals Overview

The 3131M-32.768DTTLLL-R50K is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 32.768 kHz, designed for precision timing applications. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 50 kOhms. Frequency tolerance is specified at ±20 ppm. It utilizes a 2-SMD, No Lead package configuration, suitable for surface-mount assembly in compact electronic circuits requiring stable clock references.

Crystals Feature Summary

• Provides stable reference frequency generation for integrated circuits
• Utilizes lead-free surface mount packaging for automated assembly
• Engineered for high reliability in consumer and industrial electronics

Crystals Applications

• Real-time clock circuits in portable devices
• Microcontroller system clock references
• Low-power embedded control systems

Crystals Procurement Notes

Verify the specific suffix R50K against official datasheets to confirm the 50 kOhm ESR specification. Ensure compatibility with the target PCB footprint for the 2-SMD no-lead package. Confirm that the ±20 ppm tolerance meets the system timing requirements before procurement.

Crystals Selection Notes

Select this component when a 32.768 kHz frequency is required for binary division in timekeeping applications. The 12.5 pF load capacitance must match the oscillator circuit design. Consider the 50 kOhm ESR limit for low-power consumption constraints in battery-operated devices.

Crystals Part Context

This part belongs to the 3131M series of quartz crystals from Suzhou Hangjing. The series focuses on standard frequency points for general-purpose timing. The manufacturer specializes in quartz frequency control components, offering various packages and tolerances for diverse electronic applications.

Crystals Replacement Considerations

The variant 3131M-32.768DTTLLLK offers a similar form factor but specifies a 70 kOhm ESR instead of 50 kOhms. Verify if the higher resistance value is acceptable for the specific oscillator circuit design before substitution.
