MU00801-32.768K

Overview

The MU00801-32.768K is a kHz crystal unit manufactured by NDK, designed for precise timing applications. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 80 kOhms. The component utilizes fundamental operating mode and is housed in a compact 2-SMD, No Lead package. It supports an operating temperature range of -40°C to +85°C, ensuring reliable performance across standard industrial environments.

Feature Summary

• Compact surface-mount design with no lead configuration
• High stability quartz crystal unit for accurate timekeeping
• Robust construction suitable for automated assembly processes

Applications

• Real-time clock circuits
• Microcontroller system clocks
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific suffix or variant code against the official NDK datasheet to ensure compatibility with your circuit design. Confirm that the 12.5 pF load capacitance matches your oscillator circuit requirements. Check the operating temperature range limits for your intended application environment. Ensure the 2-SMD package dimensions fit within your PCB layout constraints. Validate the ESR specifications with your host device's input impedance.

Selection Notes

Select this component when a small footprint and low cost are prioritized over extreme temperature stability. It is suitable for general-purpose timing where -40°C to +85°C coverage is sufficient. Consider alternative AEC-Q200 qualified parts if automotive reliability standards are required. Evaluate the 80 kOhm ESR against your oscillator driver strength to prevent startup failures.
