9HT11-32.768KBZB-T

Crystals Overview

The TXC CORPORATION 9HT11-32.768KBZB-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 32.768 kHz. It features a load capacitance of 6 pF and a frequency tolerance of ±50 ppm. The equivalent series resistance (ESR) is specified as 90 kOhms. The component operates within a temperature range of -40°C to +85°C. Its physical dimensions are 2.0 mm in length, 1.2 mm in width, and 0.6 mm in height, housed in a 2-SMD, no-lead package.

Crystals Feature Summary

• Fundamental mode operation for stable low-frequency timing
• Surface-mount design compatible with automated assembly processes
• Wide industrial temperature rating for environmental resilience

Crystals Applications

• Real-time clock circuits in portable electronics
• Microcontroller system oscillators
• Low-power embedded device timing references

Crystals Procurement Notes

Verify the specific suffix 'KBZB' against the manufacturer's official part number guide to ensure correct tolerance and packaging specifications. Confirm that the 90 kOhm ESR value aligns with the target circuit's drive level requirements. Check RoHS compliance status and moisture sensitivity level prior to procurement to ensure storage and reflow soldering compatibility.

Crystals Selection Notes

Select this component when a compact 2.0x1.2mm footprint is required for space-constrained designs. Choose based on the ±50 ppm tolerance requirement rather than tighter precision variants. Ensure the 6 pF load capacitance matches the oscillator circuit's external capacitor values. Verify that the higher 90 kOhm ESR is acceptable for the specific MCU or RTC input impedance.

Crystals Part Context

This part belongs to the 9HT11 series of thin-film or bulk acoustic wave crystals from TXC Corporation. It serves as a standard timing element for low-frequency applications. The series offers various tolerance and size options. This specific model provides a balance between small form factor and standard commercial/industrial temperature performance.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with similar 2x1.2mm dimensions and 6pF load capacitance. Verify pinout compatibility and electrical parameters such as ESR and tolerance before substitution.
