9HT7-32.768KDZY-T

Crystals Overview

The TXC Corporation 9HT7-32.768KDZY-T is a quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at 25°C. The component features a load capacitance of 7 pF and an equivalent series resistance (ESR) of 65 kOhms. It utilizes a 4-SMD, flat lead package with dimensions of 6.9 mm in length, 1.4 mm in width, and 1.3 mm in height. The device supports fundamental mode operation and functions within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Surface-mount construction utilizing a 4-SMD flat lead package design
• Tuning fork-type quartz resonator architecture for stable timing
• Compliance with RoHS3 environmental standards

Crystals Applications

• Real-time clock (RTC) circuits
• Digital watch timing modules
• Microcontroller system clocks

Crystals Procurement Notes

Verify the specific package configuration against schematic requirements, as datasheets may list variations such as 2-SMD or 4-SMD flat leads for similar part numbers. Confirm that the 65 kOhm ESR aligns with the oscillator circuit's drive level constraints. Ensure the 7 pF load capacitance matches the host system's design specifications to maintain accurate frequency stability.

Crystals Selection Notes

Select this component when a compact footprint is required alongside standard 32.768 kHz timing needs. The 6.9 x 1.4 x 1.3 mm size offers space efficiency compared to larger through-hole alternatives. Consider the ±20 ppm tolerance sufficient for general consumer electronics where high-precision calibration is not critical. Verify compatibility with automated pick-and-place equipment due to the flat lead package style.
