9HT11-32.768KEZF-T

Crystals Overview

The TXC Corporation 9HT11-32.768KEZF-T is a surface-mount quartz crystal resonator designed for precision timing applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±10 ppm and a total frequency stability of 30 ppm. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of approximately 70 kOhms to 90 kOhms. It utilizes a compact 2-SMD, no-lead package measuring 2 mm in length, 1.2 mm in width, and 0.6 mm in height. The device supports soldering via SMD/SMT mounting style and functions within an operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Compact 2 mm x 1.2 mm x 0.6 mm surface-mount footprint suitable for space-constrained designs
• High frequency stability of 30 ppm ensures reliable timekeeping performance
• Low power consumption characteristics inherent to high ESR design

Crystals Applications

• Mobile phone clock circuits
• Notebook computer real-time clocks
• Digital still camera timing modules

Crystals Procurement Notes

Verify the specific suffix 'KEZF' against the manufacturer's current part number guide to ensure compatibility with required moisture sensitivity levels and reflow soldering profiles. Confirm that the 12.5 pF load capacitance matches the host circuit's oscillator design requirements. Check RoHS compliance status directly on the official datasheet or product compliance page before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for low-power digital systems. Ensure the application environment stays within the -40°C to +85°C operational range. Verify that the host oscillator circuit can drive the specified 12.5 pF load capacitance effectively. Consider the 2x1.2 mm package dimensions for PCB layout constraints compared to larger standard crystals.

Crystals Part Context

This part belongs to the 9HT11 series of ultra-thin, low-profile quartz crystals from TXC Corporation. The series is engineered for portable electronics where minimal board space and low profile are critical. Similar parts in the series may vary by frequency tolerance, load capacitance, or packaging suffix, but share the same fundamental 2x1.2 mm form factor and 32.768 kHz base frequency.

Crystals Replacement Considerations

Direct substitutes include other 9HT11 series variants such as 9HT11-32.768KDZC-T or KDZF-T, provided the load capacitance and tolerance meet system requirements. Cross-manufacturer replacements must match the 2x1.2 mm outline, 12.5 pF load capacitance, and 32.768 kHz frequency to ensure electrical compatibility without redesign.
