9HT10-32.768KDZC-T

Crystals Overview

The 9HT10-32.768KDZC-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 9 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 70 kOhms and functions within a temperature range of -40°C to +85°C. Its physical dimensions are 3.2 mm in length, 1.5 mm in width, and 0.75 mm in height, housed in a compact 2-SMD, no-lead package suitable for space-constrained electronic designs.

Crystals Feature Summary

• Surface-mount design utilizing a 2-SMD, no-lead package configuration
• Fundamental mode operation optimized for low-power timing circuits
• Compliance with RoHS3 environmental standards

Crystals Applications

• Real-time clock circuits in portable electronics
• Microcontroller system timing references
• Low-frequency oscillator stages in embedded systems

Crystals Procurement Notes

Verify the specific suffix 'C' against the official TXC part number guide to confirm the 9 pF load capacitance specification. Ensure that the ordering documentation explicitly matches the 9HT10-32.768KDZC-T identifier to avoid confusion with similar variants such as KDZY or KDZB which possess different electrical parameters. Cross-reference the datasheet for accurate handling instructions regarding moisture sensitivity level one.

Crystals Selection Notes

Select this component when a 32.768 kHz reference requires a 9 pF load capacitance interface. The ±20 ppm tolerance suits general-purpose timekeeping rather than high-precision synchronization. Consider the 3.2x1.5 mm footprint compatibility with existing PCB layouts. Evaluate the 70 kOhm ESR against the oscillator circuit requirements to ensure stable startup conditions within the specified -40°C to +85°C operating range.

Crystals Part Context

This part belongs to the TXC 9HT10 series of quartz crystals, characterized by small form factors and surface-mount compatibility. The series targets cost-effective timing solutions for consumer and industrial devices. The 9HT10 designation indicates a specific dimensional and electrical profile distinct from other TXC families like 9HT9 or 9HT11, ensuring standardized integration across various product lines requiring 32.768 kHz references.

Crystals Replacement Considerations

The 9HT10-32.768KDZY-T serves as a verified alternative within the same manufacturer lineup, though it specifies a 7 pF load capacitance instead of 9 pF. Designers must verify oscillator circuit compatibility when substituting between these variants due to the difference in required load capacitance values.
