9HT10D-32.768KHZY-T

Crystals Overview

The 9HT10D-32.768KHZY-T is a quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 32.768 kHz with a high initial frequency tolerance of ±5 ppm at 25°C. The component features a load capacitance of 7 pF and an equivalent series resistance (ESR) of 70 kOhms. It utilizes a 2-SMD, no-lead package with dimensions of 3.0 mm in length and 1.5 mm in width. This device is suitable for precision timing circuits requiring tight frequency stability.

Crystals Feature Summary

• High initial frequency accuracy of ±5 ppm ensures precise timekeeping.
• Compact 3.0 x 1.5 mm SMD footprint supports space-constrained designs.
• Fundamental mode operation provides stable oscillation characteristics.

Crystals Applications

• Real-time clock circuits
• Microcontroller system clocks
• Portable electronic devices

Crystals Procurement Notes

Verify the specific suffix 'ZY' against official TXC documentation to confirm the ±5 ppm tolerance and 7 pF load capacitance parameters. Ensure the ordering part number matches the exact physical dimensions and ESR specifications required by the design. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or packaging configurations before finalizing procurement.

Crystals Selection Notes

Select this component when superior frequency stability compared to standard ±10 or ±20 ppm crystals is required. The 7 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 3.0 x 1.5 mm package size relative to available PCB real estate. Verify that the 70 kOhm ESR is compatible with the host oscillator's drive level requirements.

Crystals Part Context

This part belongs to the 9HT10D series of quartz crystals from TXC Corporation. The series offers various tolerance options, with this specific model providing the tighter ±5 ppm specification. It complements other variants like the 9HT10D-32.768KEZY-T which offers ±10 ppm tolerance, allowing designers to choose based on cost and performance needs.

Crystals Replacement Considerations

The 9HT10D-32.768KEZY-T is a documented similar alternative from TXC Corporation, offering ±10 ppm tolerance instead of ±5 ppm. Designers should verify if the looser tolerance meets their application requirements before substituting.
