9HT11-32.768KDZF-T

Crystals Overview

The 9HT11-32.768KDZF-T is a surface-mount tuning fork quartz crystal manufactured by TXC Corporation, distributed under the FTS brand designation. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm and a load capacitance of 12.5 pF. The component features an equivalent series resistance (ESR) of 90 kOhms and utilizes a 2-SMD no-lead package measuring 2.0 mm in length, 1.2 mm in width, and 0.6 mm in height. It supports base mode operation within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Compact 2.0x1.2mm SMD footprint designed for space-constrained mobile and wearable electronics
• Tuning fork architecture optimized for low-power real-time clock applications
• RoHS3 compliant construction ensuring environmental safety standards

Crystals Applications

• Real-time clock circuits in mobile phones and notebooks
• Wearable electronic devices requiring precise timekeeping
• Low-power digital consumer electronics

Crystals Procurement Notes

Verify that the supplier provides official TXC Corporation documentation confirming the 9HT11 series specifications. Ensure the part number suffix matches the required tolerance and packaging format. Cross-reference the manufacturer date code and RoHS3 compliance status against current regulatory requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for RTC functions in compact portable devices. The 12.5 pF load capacitance must match the oscillator circuit design. Consider the 90 kOhm ESR value for drive level sensitivity. Verify that the 2.0x1.2mm package dimensions fit the available PCB real estate compared to larger 3215 or 3225 packages.

Crystals Part Context

This component belongs to the TXC 9HT Series of quartz crystals, which are specifically engineered for high-volume consumer electronics. The 9HT11 variant represents a smaller form factor within the series, targeting applications where board space is limited. It shares the standard 32.768 kHz frequency common across most microcontroller-based timekeeping systems.

Crystals Replacement Considerations

Public confirmed substitute part numbers include ECS-.327-9-16-TR from ECS Inc. and LFXTAL066198 from IQD Frequency Products. These alternatives offer similar electrical characteristics and package types for direct replacement in compatible designs.
