• Operates reliably across standard industrial temperature ranges

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system clocks
• Precision timing references in embedded systems

Crystals Procurement Notes

Verify that the supplier provides official documentation confirming the RoHS3 compliance status and the specific manufacturing origin. Ensure the order specifies the correct packaging type, as bulk quantities may differ from single-unit samples. Confirm that the vendor is an authorized distributor of HKC Hong Kong X'tals Ltd products to guarantee authenticity and traceability of the components.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for low-power digital logic or timekeeping functions. The ±5ppm tolerance makes it suitable for applications where moderate drift is acceptable without external calibration. Consider the 40 kOhm ESR limit to ensure compatibility with oscillator circuit requirements. The radial leaded package facilitates easy integration into standard printed circuit board layouts.

Crystals Part Context

This part belongs to the 3x8 Cylinder series of quartz crystals manufactured by HKC. These components are widely used in general-purpose electronic devices requiring accurate timekeeping or frequency generation. The cylindrical can construction offers mechanical protection for the internal quartz element while maintaining a small footprint.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, ±5ppm tolerance, 12.5pF load capacitance, and cylindrical radial package dimensions. Verify that alternative manufacturers offer comparable ESR specifications and operating temperature ranges to ensure functional equivalence.
