9HT10D-32.768KAZC-T

Crystals Overview

The TXC Corporation 9HT10D-32.768KAZC-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 32.768 kHz. It features a compact SMD-2 package with dimensions of 3.0 mm in length, 1.5 mm in width, and a maximum height of 0.75 mm. The component provides a frequency tolerance of ±30 ppm at 25°C and supports a load capacitance of 9 pF. It is designed for operation within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Provides stable 32.768 kHz timing signals suitable for real-time clock applications
• Utilizes a low-profile surface-mount design for space-constrained PCB layouts
• Ensures frequency accuracy with ±30 ppm stability at standard ambient conditions

Crystals Applications

• Real-time clock circuits in consumer electronics
• Timekeeping modules in portable devices
• Microcontroller system oscillators requiring precise low-frequency references

Crystals Procurement Notes

Verify the specific load capacitance requirement of 9 pF against the target circuit design to ensure proper frequency calibration. Confirm that the host application accommodates the ±30 ppm tolerance specification at 25°C. Ensure the PCB footprint matches the 3.0 mm x 1.5 mm SMD-2 package dimensions. Check compatibility with the specified operating temperature range of -40°C to +85°C for the intended environment.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required with a 9 pF load capacitance. Choose this model over variants with different tolerances if ±30 ppm meets the system accuracy needs. Consider the 3.0 mm x 1.5 mm package size for board space optimization compared to larger 3.2 mm x 1.5 mm alternatives. Verify thermal requirements align with the -40°C to +85°C operational range.

Crystals Part Context

This part belongs to the TXC 9HT10 series of quartz crystals, which are widely used for low-frequency timing applications. The series offers various package sizes and electrical specifications to suit different design constraints. The 9HT10D variant specifically denotes the 3.0 mm x 1.5 mm form factor, distinguishing it from other series members like the 9HT10 or 9HT11.

Crystals Replacement Considerations

Substitutes must match the 32.768 kHz frequency, 9 pF load capacitance, and 3.0 mm x 1.5 mm package. Variants such as 9HT10D-32.768KDZY-T may differ in tolerance or load capacitance; verify datasheet alignment before replacement.
