• Designed for surface-mount assembly in compact electronic circuits.
• Complies with automotive reliability standards including AEC-Q200 certification.

Crystals Applications

• Real-time clock circuits in embedded systems
• Timing sources for portable consumer electronics
• Low-power wearable device architectures

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as per manufacturer documentation. Confirm that the 6pF load capacitance matches the target circuit design requirements. Ensure the 90 kOhm ESR value is compatible with the oscillator input impedance specifications. Validate the AEC-Q200 qualification status if automotive deployment is intended.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for space-constrained designs utilizing the 2012 metric footprint. The ±30 ppm tolerance suits general-purpose timekeeping where high precision is not critical. Consider the 6pF load capacitance requirement against existing circuit loading conditions to ensure accurate frequency operation without external trimming.

Crystals Part Context

This part belongs to the 9HT11 series of thin-film or standard quartz crystals from TXC Corporation. It shares the physical 2012 package dimensions with variants like 9HT11-32.768KBZB-T but differs in electrical parameters such as load capacitance and ESR. The series targets cost-sensitive applications requiring reliable surface-mount timing solutions.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz crystals in 2-SMD packages with similar 6pF load capacitance. Verify ESR compatibility, as values like 70 kOhms or 90 kOhms affect start-up reliability. Check if alternative manufacturers offer equivalent AEC-Q200 qualified parts for automotive continuity.
