8038S43276BMDANDNVE-CT

Crystals Overview

The HKC 8038S43276BMDANDNVE-CT is a tuning fork crystal oscillator designed for precision timing applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20ppm. The component features a load capacitance of 12.5pF and an equivalent series resistance (ESR) of 50 kOhms. It is housed in a compact 4-SOJ package with a 5.50mm pitch, suitable for surface-mount assembly.

Crystals Feature Summary

• Precision timing stability via ±20ppm frequency tolerance
• Compact surface-mount design in 4-SOJ package
• Optimized for low-power real-time clock circuits

Crystals Applications

• Real-time clock (RTC) modules
• Wearable electronic devices
• Smart home appliances

Crystals Procurement Notes

Verify the specific suffix 'NVE' against manufacturer documentation to confirm exact manufacturing lot or environmental compliance status. Ensure the 4-SOJ footprint matches the target PCB layout dimensions. Confirm that the 50 kOhm ESR aligns with the host circuit's drive level requirements to prevent over-driving the crystal.

Crystals Selection Notes

Select this component when a stable 32.768 kHz reference is required for timekeeping functions. The ±20ppm tolerance suits general consumer electronics where high-precision calendar accuracy is not critical. Consider the 12.5pF load capacitance compatibility with the oscillator circuit's input capacitance to ensure proper oscillation startup.

Crystals Part Context

This part belongs to the family of tuning fork crystals manufactured by HKC. While HKC is primarily known for display panels, this specific component addresses the passive electronic component market. It serves as a fundamental timing element distinct from the company's active display products.

Crystals Replacement Considerations

Cross-reference with other 32.768 kHz crystals in 4-SOJ packages. Verify that substitute parts match the 12.5pF load capacitance and 50 kOhm ESR specifications. Ensure the replacement maintains the same physical dimensions and pinout configuration for direct board compatibility.
