AH-32.768KBZF-T

Crystals Overview

The AH-32.768KBZF-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, designed for precise timekeeping applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±50 ppm at 25°C. The component utilizes a fundamental oscillation mode and features a load capacitance of 12.5 pF. It is housed in a compact 2-SMD, no lead package measuring 3.20 mm x 1.50 mm with a maximum height of 0.85 mm. The device supports an operating temperature range from -40°C to +85°C and exhibits an equivalent series resistance (ESR) of 70 kOhms.

Crystals Feature Summary

• Compact 3.2x1.5mm SMD footprint suitable for space-constrained designs
• Fundamental mode operation for stable low-frequency timing
• Automotive-grade reliability certification

Crystals Applications

• Real-time clock circuits in consumer electronics
• Wearable devices requiring small form factors
• IoT modules with strict size limitations

Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet specification of ±50 ppm, as this variant differs from higher precision models. Confirm that the 12.5 pF load capacitance matches the target microcontroller's oscillator circuit design. Ensure the operating temperature range of -40°C to +85°C meets the environmental conditions of the final application before ordering.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is needed in a minimal 3215 package. It serves as a direct replacement for other 32.768 kHz crystals in the same footprint provided the load capacitance and ESR values are compatible with the host system. Consider the ±50 ppm tolerance sufficient for general purpose RTCs but not for high-precision chronometers.

Crystals Part Context

This part belongs to the AH series of quartz crystals from TXC Corporation, which focuses on small-sized tuning fork crystals. The AH series is widely used in portable electronics where board space is limited. This specific model represents a standard commercial/automotive grade option within the lineup, balancing cost and performance for mass-produced devices.

Crystals Replacement Considerations

The AH-32.768KAZF-T is listed as a parameter-equivalent alternative. Both share the same 32.768 kHz frequency, 12.5 pF load capacitance, and 3215 package dimensions. Verify if the A variant's ±30 ppm tolerance offers necessary accuracy improvements over the Z variant's ±50 ppm specification.
