9HT11-32.768KEZC-T

Crystals Overview

The TXC CORPORATION 9HT11-32.768KEZC-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 load capacitance of 9 pF. The component features an equivalent series resistance (ESR) of 90 kOhms and supports fundamental mode operation. It is housed in a compact 2-SMD, no-lead package measuring 2.00 mm in length and 1.20 mm in width, with a maximum height of 0.50 mm. The device is rated for an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

• Lead-free construction compliant with environmental regulations

Crystals Applications

• Real-time clock circuits in portable electronics
• Microcontroller system oscillators
• Wearable health monitoring devices
• Smart home IoT sensors

Crystals Procurement Notes

Verify the specific suffix 'KEZC' against the manufacturer's official datasheet to confirm the exact load capacitance and ESR specifications, as minor variations exist within the 9HT11 series. Ensure the ordering quantity aligns with standard tape-and-reel packaging requirements defined by TXC Corporation. Cross-reference the ECCN classification EAR99 for export compliance needs prior to procurement.

Crystals Selection Notes

Select this component when a 32.768 kHz reference requires tighter frequency stability than standard ±20 ppm parts offer. The 9 pF load capacitance must match the oscillator circuit design parameters to ensure accurate frequency generation. Consider the 2.00 x 1.20 mm package dimensions for PCB layout constraints compared to larger 3.2 x 1.5 mm alternatives in the same product family.

Crystals Part Context

This part belongs to the 9HT11 series of tuning fork crystals manufactured by TXC Corporation. The series provides various load capacitance options including 6 pF, 9 pF, and 12.5 pF variants. These components are widely used in low-power digital systems requiring precise second-level timing signals. The 9HT11 series represents a modernization of earlier 9HT10 designs with optimized package dimensions.

Crystals Replacement Considerations

Direct substitutes include the 9HT11-32.768KDZC-T, which shares similar electrical characteristics but may differ in load capacitance or tolerance specifications. Verify that any replacement maintains the 9 pF load capacitance requirement to prevent frequency drift in the host oscillator circuit.
