Crystals Procurement Notes

Verify the exact manufacturer designation as HKC is primarily known for displays; confirm if this is a rebranded or specific line item. Ensure the 4-SOJ package dimensions match the PCB footprint requirements. Check that the 6 pF load capacitance aligns with the host circuit's design specifications to avoid frequency drift issues during implementation.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for digital clocks or microcontroller peripherals. The ±20 ppm tolerance is suitable for general consumer electronics where high-precision atomic timing is not mandatory. Consider the 50 Ohm series resistance for impedance matching within the oscillator circuit loop to ensure stable startup and operation.

Crystals Part Context

This part belongs to the category of passive electronic components, specifically quartz crystals. While the brand HKC is widely recognized for semiconductor display technologies, this specific item functions as a discrete timing element.
