Crystals Feature Summary

• Provides stable 32.768 kHz frequency reference for real-time clock applications
• Compact SMD2012 surface-mount package design for automated assembly
• Standard 9 pF load capacitance compatibility with common oscillator circuits

Crystals Applications

• Real-time clock (RTC) modules in consumer electronics
• Digital watches and time-keeping devices
• Embedded systems requiring low-frequency timing references

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest specification sheet to ensure compliance with current RoHS directives and material composition requirements. Confirm that the 80 kOhm ESR limit aligns with the target circuit's drive level specifications to prevent over-driving the crystal. Cross-reference the package marking codes with official documentation to distinguish between genuine components and potential counterfeits during incoming inspection.

Crystals Selection Notes

Select this component when a low-cost, standard-tolerance timing source is required for non-critical timekeeping functions. The ±20 ppm tolerance is suitable for general-purpose RTCs but may require calibration in high-precision environments. Ensure the PCB layout supports the SMD2012 footprint and maintains adequate clearance from high-noise traces to preserve signal integrity during operation.
