9HT10D-32.768KBZF-T

Crystals Overview

The TXC Corporation 9HT10D-32.768KBZF-T is a surface-mount quartz crystal designed for low-frequency timing applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±50 ppm at 25°C. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) maximum of 70 kOhms. It utilizes a tuning fork mode of operation within the 3.0 mm x 1.5 mm SMD package, measuring 0.9 mm in height. The device supports a wide operating temperature range from -40°C to +85°C and is supplied in cut tape or reel packaging.

Crystals Feature Summary

• Provides stable 32.768 kHz timing signals via fundamental tuning fork resonance
• Designed for compact surface-mount integration in space-constrained electronics
• Operates reliably across industrial temperature ranges without external compensation

Crystals Applications

• Real-time clock circuits in portable consumer devices
• Microcontroller system oscillators requiring precise timekeeping
• Low-power embedded monitoring systems

Crystals Procurement Notes

Verify the specific suffix 'B' confirms the ±50 ppm tolerance requirement against your circuit design specifications. Ensure the PCB footprint matches the 3.0x1.5mm outline dimensions. Confirm that the 12.5pF load capacitance aligns with the host oscillator circuit requirements to maintain frequency accuracy. Check RoHS compliance documentation for regulatory adherence.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is needed with moderate frequency stability. The ±50 ppm tolerance suits general-purpose timekeeping where high precision is not critical. Consider the 12.5pF load capacitance compatibility with the driving circuit. Evaluate the 70k Ohm ESR limit against the oscillator's drive level constraints to ensure reliable startup.

Crystals Part Context

This part belongs to the 9HT10 series of quartz crystals manufactured by TXC Corporation. The series offers various frequency tolerances and package sizes. The 9HT10D variant specifically denotes the 3.0x1.5mm form factor. This model represents a cost-effective solution for basic timing needs compared to higher-precision variants in the same family.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 9HT10-32.768KBZF-T and 9HT10-32.768KBZC-T. Verify that substitutes match the 12.5pF load capacitance and ±50ppm tolerance. Ensure the replacement maintains the same 3.0x1.5mm package dimensions for direct board compatibility.
