It operates at a fundamental frequency of 32.768 kHz with a frequency tolerance of ±20 ppm. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 50 kOhms. It is housed in a compact 2-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Crystals Feature Summary

• Provides stable frequency control at 32.768 kHz for timing applications
• Designed for surface-mount technology with a leadless two-terminal SMD package
• Engineered for low power consumption suitable for portable electronics

Crystals Applications

• Real-time clock circuits in computing devices
• Timing references in medical monitoring equipment
• Frequency standards in industrial control systems

Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as variations such as 70 kOhms may exist for similar part numbers. Confirm the package dimensions and soldering profile requirements to ensure compatibility with automated surface-mount assembly processes. Request the RoHS compliance certificate and material declaration to meet environmental regulations for electronic assemblies.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for low-power digital logic interfaces. Ensure the circuit design accommodates the specified 6 pF load capacitance to maintain frequency accuracy within the ±20 ppm tolerance. Evaluate the 50 kOhms ESR limit to guarantee sufficient drive level stability without overdriving the crystal element.

Crystals Part Context

This crystal belongs to the HC21M4 or similar series from Suzhou Hangjing, which targets wireless LAN, mobile communication, and Bluetooth applications. The manufacturer specializes in quartz frequency controlling units, including crystals, oscillators, and filters, serving sectors like IT, automotive, and consumer electronics with high-reliability components.

Crystals Replacement Considerations

Cross-reference with other 32.768 kHz SMD crystals offering ±20 ppm tolerance and 6 pF load capacitance. Verify that substitute parts match the 2-SMD no-lead footprint and operate within the same temperature range. Ensure the replacement maintains comparable ESR specifications to prevent oscillator startup failures.
