AH-32.768KDWF-T

Crystals Overview

The AH-32.768KDWF-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 12.5 pF and a frequency tolerance of ±20 ppm. The device supports an extended operating temperature range from -40°C to +125°C and complies with the AEC-Q200 automotive qualification standard. Packaged in a compact 2-SMD (3.2mm x 1.5mm) footprint, it utilizes lead-free solder materials and meets RoHS directives.

Crystals Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Extended industrial temperature range up to 125°C
• Lead-free compliant construction

Crystals Applications

• Automotive electronic timing circuits
• Industrial real-time clock modules
• High-reliability consumer electronics

Crystals Procurement Notes

Verify the specific suffix KDWF against official TXC documentation to confirm the exact tolerance and temperature rating, as variations exist within the AH series. Ensure compatibility with automated surface-mount assembly processes given the small 2-SMD package dimensions. Confirm that the 12.5pF load capacitance aligns with the target circuit design requirements before finalizing procurement.

Crystals Selection Notes

Select this component when high-temperature stability exceeding standard industrial limits is required, specifically for environments reaching 125°C. The AEC-Q200 certification makes it suitable for automotive subsystems where rigorous reliability testing is mandated. Engineers must account for the 12.5pF load capacitance in PCB layout calculations to ensure accurate frequency generation without external trimming.

Crystals Part Context

This part belongs to the AH series of low-profile quartz crystals from TXC Corporation. The series is characterized by its small 3.2mm x 1.5mm SMD form factor, which facilitates miniaturization in modern electronic devices. The AH series generally targets applications requiring stable timekeeping references in space-constrained designs.
