9HT12-32.768KBZF-T

Crystals Overview

The TXC CORPORATION 9HT12-32.768KBZF-T is a surface-mount quartz crystal resonator operating at a nominal frequency of 32.768 kHz. It belongs to the 9HT12 series and utilizes a tuning fork configuration for base mode operation. The component features a load capacitance of 12.5 pF and a frequency tolerance of ±50 ppm. Its equivalent series resistance (ESR) is specified at 90 kOhms maximum. The device is housed in a compact 2-SMD, no-lead package with dimensions of 4.10 mm length by 1.50 mm width and a maximum height of 0.85 mm. It supports an operating temperature range from -40°C to +85°C.

Crystals Feature Summary

• Surface-mount tuning fork quartz crystal designed for low-frequency timing applications
• Base mode operation with high equivalent series resistance suitable for specific oscillator circuits
• Compliant with RoHS3 standards and classified under EAR99 export control

Crystals Applications

• Real-time clock circuits in portable electronic devices
• Microcontroller system timing references
• Low-power embedded monitoring systems

Crystals Procurement Notes

Verify the exact load capacitance requirement of the target oscillator circuit against the 12.5 pF specification to ensure frequency accuracy. Confirm that the PCB footprint matches the 4.10mm x 1.50mm SMD package dimensions. Check for any specific reflow soldering profile requirements defined in the official datasheet to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required in a small 2-SMD form factor. The ±50 ppm tolerance is suitable for general-purpose timekeeping where high precision is not critical. Consider the 90 kOhm ESR value to ensure compatibility with the driving circuit's oscillation capability. Compare against other 9HT series variants if different load capacitances or tighter tolerances are needed.

Crystals Part Context

This part is a member of the TXC 9HT12 series of quartz crystals. It shares the same physical package dimensions as the 9HT9 series but differs in electrical specifications such as load capacitance and ESR. It serves as a direct replacement for legacy through-hole or larger SMD crystals in space-constrained designs requiring standard watch frequencies.
