• Compact 3.0x1.5mm SMD footprint for space-constrained designs
• High stability ±10 ppm frequency tolerance
• Extended operating temperature range up to 125°C

Crystals Applications

• Automotive electronic control units (ECUs)
• Real-time clock (RTC) circuits in IoT devices
• Low-power wearable electronics
• Industrial sensor nodes requiring precise timing

Crystals Procurement Notes

Verify the specific suffix 'KEWC' against the manufacturer's latest datasheet to confirm the 9pF load capacitance and 125°C temperature rating, as these parameters distinguish this variant from other AH-series models. Ensure that the ordering documentation explicitly references AEC-Q200 compliance if automotive qualification is required for the final assembly. Cross-check the package dimensions with the PCB footprint library to prevent soldering defects during surface mount assembly.

Crystals Selection Notes

Select this component when a small form factor is critical alongside high thermal stability. The 9pF load capacitance requires careful calculation of external circuit capacitors to maintain accuracy. Consider the 70kOhm ESR when designing oscillator circuits to ensure sufficient drive level without overdriving the crystal. This model is suitable for applications demanding both miniaturization and robust performance under varying thermal conditions.

Crystals Part Context

This part belongs to the AH series of low-profile quartz crystals from TXC Corporation. The series is characterized by its thin profile and suitability for modern surface-mount technology processes. The AH series generally targets consumer, industrial, and automotive markets where space savings and long-term frequency stability are paramount design constraints.

Crystals Replacement Considerations

Direct substitutes include AH-32.768KDZC-T, which shares similar electrical characteristics but may differ in load capacitance or temperature range specifications. Verify compatibility with the target oscillator circuit before substitution.
