9HT7-32.768KBZY-T

Crystals Overview

The 9HT7-32.768KBZY-T is a quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 12.5 pF and a frequency tolerance of ±50 ppm. The component features an equivalent series resistance (ESR) of 65 kOhms and utilizes a 4-SMD, flat lead package measuring 0.264 inches in length by 0.126 inches in width. It supports operation within a temperature range of -40°C to +85°C and is supplied in cut tape or reel packaging.

Crystals Feature Summary

• Fundamental mode oscillation at 32.768 kHz
• Surface-mount 4-SMD flat lead configuration
• Wide industrial operating temperature range

Crystals Applications

• Real-time clock circuits
• Microcontroller system clocks
• Portable electronic devices requiring low power consumption

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as datasheet sources indicate variations between 7pF and 12.5pF for this part number. Confirm that the 4-SMD flat lead package dimensions align with the printed circuit board footprint constraints. Ensure the ±50 ppm frequency tolerance meets the system timing accuracy specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions in compact electronics. The 4-SMD flat lead package offers a suitable balance between mechanical stability and space efficiency for consumer devices. Consider the ±50 ppm tolerance adequate for general-purpose real-time clock applications where high precision is not critical.

Crystals Part Context

This component belongs to the 9HT7 series of quartz crystals from TXC Corporation, which are optimized for cost-effective mass production in consumer electronics. The series provides reliable frequency stability for basic timing applications. As an active lifecycle part, it remains available for new designs requiring standard watch-frequency references in small form factors.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz crystals with identical 4-SMD flat lead packages and compatible load capacitance values. Verify that alternative parts maintain the same ±50 ppm tolerance and -40°C to +85°C temperature range to ensure functional equivalence in existing designs.
