8038S43276BMDADBNVE-TR

Crystals Overview

The HKC 8038S43276BMDADBNVE-TR is a quartz crystal resonator operating at a fundamental frequency of 32.768 kHz with a tolerance of ±20 ppm. It features a load capacitance of 12.5 pF and is housed in a 4-SOJ surface-mount package with a 5.50 mm lead pitch. This component serves as a precise timing reference for low-frequency clock applications.

Crystals Feature Summary

• Provides stable oscillation at standard real-time clock frequencies
• Designed for surface-mount assembly processes
• Engineered for consistent performance within specified temperature ranges

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system clocks
• Low-power embedded devices requiring precise timekeeping

Crystals Procurement Notes

Verify the exact manufacturer designation, as HKC primarily manufactures displays; this part may be sourced from third-party distributors or represent a specific branding variant. Confirm the 4-SOJ package dimensions and pinout against official datasheets to ensure compatibility with PCB footprints. Validate the ±20 ppm tolerance requirement for your specific application before procurement.

Crystals Selection Notes

Select this component when a 32.768 kHz frequency is required for timekeeping functions. The 12.5 pF load capacitance must match the oscillator circuit design. Ensure the 4-SOJ package fits the available board space. Consider the ±20 ppm accuracy sufficient for general-purpose RTCs but verify if tighter tolerances are needed for high-precision applications.

Crystals Part Context

This crystal resonator belongs to the family of low-frequency timing components used in digital systems. While the brand name suggests display manufacturing origins, the component itself is a passive electronic part essential for synchronizing data and maintaining time in various integrated circuits and standalone modules.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz crystals in 4-SOJ packages with similar load capacitance and tolerance. Verify equivalent electrical parameters such as ESR and drive level sensitivity when cross-referencing alternative manufacturers.
