AH-32.768KEZC-T

Crystals Overview

The AH-32.768KEZC-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 9 pF and a frequency tolerance of ±10 ppm. The component features an equivalent series resistance (ESR) of 70 kOhms and supports base mode operation. It is housed in a compact 2-SMD, No Lead package measuring 3.2 mm x 1.5 mm with a maximum height of 0.85 mm. 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 no-lead package design suitable for space-constrained PCB layouts
• High frequency stability with ±10 ppm tolerance for precise clock generation
• Wide industrial temperature rating ensuring reliable performance in harsh environments

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system clock sources
• Portable battery-powered devices requiring low power consumption

Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as source data indicates variations between 6 pF, 9 pF, and other values for this part number. Confirm the package dimensions match your footprint constraints. Ensure compliance with RoHS3 regulations if required by your manufacturing standards. Cross-reference the ESR value with your oscillator circuit specifications to guarantee proper startup and stability.

Crystals Selection Notes

Select this component when a small form factor is critical alongside moderate frequency accuracy requirements. The 9 pF load capacitance suits standard microcontroller interfaces without external trimming. Consider the -40°C to +85°C range for industrial or automotive adjacent applications. Compare against variants like AH-32.768KDZY-T if higher tolerance (±20 ppm) or different load capacitance is acceptable for cost optimization.

Crystals Part Context

This part belongs to the AH series of thin-film quartz crystals from TXC Corporation. The series focuses on miniaturized SMD solutions for wearable and IoT devices. Unlike larger through-hole crystals, these offer automated assembly compatibility. The specific KEZC suffix denotes the 9 pF load capacitance variant within the broader 32.768 kHz product line.

Crystals Replacement Considerations

Direct substitutes include the AH-32.768KDZY-T, which offers similar packaging but with ±20 ppm tolerance and 7 pF load capacitance. Other parameter-equivalent options from manufacturers like Micro Crystal may require verification of pinout and electrical characteristics. Always validate mechanical fit and electrical parameters before substitution.
