9HT7-32.768KBZF-T

Crystals Overview

The TXC CORPORATION 9HT7-32.768KBZF-T is a surface-mount quartz crystal resonator designed for timing applications. It operates at a nominal frequency of 32.768 kHz with a ±50 ppm tolerance. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 65 kOhms. It utilizes a tuning fork type design for fundamental mode operation. The physical dimensions are 2.0 mm in length, 1.2 mm in width, and 0.6 mm in height. It supports a standard operating temperature range from -40°C to +85°C.

Crystals Feature Summary

• Compact 2.0mm x 1.2mm surface mount package suitable for space-constrained designs
• Tuning fork architecture optimized for low-power real-time clock applications
• Compliant with RoHS3 standards for environmental safety

Crystals Applications

• Mobile phone timing circuits
• Notebook computer real-time clocks
• Digital still camera (DSC) systems

Crystals Procurement Notes

Verify the specific load capacitance requirement of the host oscillator circuit against the 12.5pF specification. Confirm that the ±50ppm initial tolerance meets the system's long-term accuracy needs. Ensure the PCB footprint matches the 2.0mm x 1.2mm outline. Check for RoHS3 compliance requirements in the target market.

Crystals Selection Notes

Select this component when a small form factor is required for portable electronics. The 12.5pF load capacitance is standard for many microcontroller RTC interfaces. Consider the ±50ppm tolerance if high precision is not critical. Compare against the 9HT7-32.768KDZF-T variant if tighter ±20ppm tolerance is necessary for the application.

Crystals Part Context

This part belongs to the TXC 9HT7 series of ultra-small quartz crystals. The series is engineered specifically for mobile and consumer electronics where board space is limited. It serves as a timekeeping reference for digital logic circuits requiring a stable 32.768 kHz signal.

Crystals Replacement Considerations

The 9HT7-32.768KDZF-T is a direct substitute offering improved ±20ppm tolerance while maintaining identical dimensions and electrical characteristics.
