The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 70 kOhms. It is housed in a compact 2-SMD, No Lead package with dimensions of 3.2mm x 1.5mm x 0.75mm. The device supports an operating temperature range from -40°C to +85°C, ensuring reliability in various environmental conditions.

Feature Summary

• Provides high frequency stability with ±20 ppm tolerance at 25°C
• Compact 2-SMD no-lead package design for space-constrained applications
• Operates reliably across a wide temperature range of -40°C to +85°C

Applications

• Synchronization solutions requiring precise timing
• Real-time clock circuits in consumer electronics
• Microcontroller system clocks

Procurement Notes

Verify the manufacturer designation carefully, as similar part numbers exist under TXC Corporation. Confirm the specific suffix KDWF-T matches the required 12.5pF load capacitance and 70kOhm ESR specifications. Ensure the sourcing channel provides original components to guarantee performance consistency and avoid counterfeit risks.

Selection Notes

Select this component when a 32.768 kHz reference is needed with moderate stability requirements. The 12.5pF load capacitance must match the oscillator circuit design. Consider the 70kOhm ESR limit for power consumption constraints. The SMD form factor suits automated assembly processes.

Part Context

This part belongs to the QT3C series of thin-film or bulk acoustic wave crystals optimized for low-power, small-footprint timing needs. The series offers various tolerance and capacitance options to fit different controller interfaces.

Replacement Considerations

QT3C-32.768KDZC-T (9pF load), QT3C-32.768KAZF-T (TXC, 12.5pF load). Verify load capacitance compatibility before substitution.
