MU01501-32.768K

Overview

The MU01501-32.768K is a surface-mount quartz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 80 kΩ maximum. It utilizes a two-terminal surface-mount package without lead construction, designed for automated assembly processes.

Feature Summary

• Surface-mount design with lead-free construction
• High stability frequency output at 32.768 kHz
• Compact two-terminal package format

Applications

• Real-time clock circuits in consumer electronics
• Timekeeping modules in portable devices
• Low-frequency reference sources in embedded systems

Procurement Notes

Verify the specific manufacturing lot date code against project requirements to ensure material freshness. Confirm that the 80 kΩ ESR specification aligns with the oscillator circuit's drive level constraints. Ensure the 6 pF load capacitance matches the host system's input capacitance calculations to maintain the specified ±20 ppm accuracy. Validate package dimensions for PCB footprint compatibility before finalizing procurement orders.

Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping applications. The ±20 ppm tolerance suits general-purpose clocks but may be insufficient for high-precision timing needs requiring tighter tolerances. The 80 kΩ ESR indicates suitability for low-power oscillator designs. Consider thermal stability requirements if operating outside standard ambient conditions.

Part Context

This part belongs to NDK's portfolio of quartz crystal resonators. NDK manufactures these components using proprietary quartz processing technologies established since 1948. The company focuses on providing reliable oscillation sources for mobile communications, office automation, and automotive electronics. This specific model represents a standard frequency option within their surface-mount crystal lineup.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching frequency, load capacitance, ESR, and package dimensions. Verify electrical parameters with alternative suppliers to ensure circuit compatibility.
