AH-32.768KDZB-T

Crystals Overview

The AH-32.768KDZB-T is a surface-mount tuning fork crystal manufactured by TXC Corporation, designed for precise timekeeping applications. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 6 pF and a frequency tolerance of ±20 ppm. The component utilizes an AT-cut quartz resonator housed in a compact 2-SMD, No Lead package measuring 3.20 mm in length, 1.50 mm in width, and a maximum height of 0.85 mm. It supports base mode operation and features an equivalent series resistance (ESR) of 70 kOhms. The device is rated for an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Compact 2-SMD footprint suitable for space-constrained designs
• AT-cut quartz construction for stable frequency performance
• Compliant with AEC-Q200 automotive reliability standards

Crystals Applications

• Real-time clock circuits in consumer electronics
• Wearable technology devices
• IoT sensor modules requiring low power consumption

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this variant specifies 6 pF rather than the common 12.5 pF standard. Confirm that the 2-SMD no-lead package dimensions align with the PCB footprint constraints. Ensure the selected supplier provides documentation confirming compliance with the specified RoHS3 regulations and AEC-Q200 qualification status prior to final procurement authorization.

Crystals Selection Notes

Select this component when a small form factor is critical alongside automotive-grade reliability requirements. The 6 pF load capacitance necessitates careful matching with external circuit capacitors to ensure accurate oscillation frequency. Consider the 70 kOhm ESR value for oscillator circuit stability analysis. This part is appropriate for industrial and automotive environments where the -40°C to +85°C temperature range is sufficient.

Crystals Part Context

This model belongs to the AH series of tuning fork crystals from TXC Corporation, which are engineered for high-frequency stability in miniature packages. The AH series is widely utilized in applications demanding low current consumption and long-term frequency stability. The KDZB suffix indicates specific packaging and tolerance characteristics within the broader product line.

Crystals Replacement Considerations

The AH-32.768KDZB-T may be replaced by the AH-32.768KDZY-T if a 7 pF load capacitance is acceptable for the application. Cross-reference with Micro Crystal CM7V series parts for parameter-equivalent alternatives, ensuring package compatibility and electrical specifications match the original design requirements.
