MU01611-32.768K

Overview

The MU01611-32.768K is a surface-mount crystal resonator manufactured by NDK, designed for precise timing applications. It operates at a fundamental frequency of 32.768 kHz with a standard load capacitance of 9 pF and a frequency tolerance of ±20 ppm. The component utilizes a leadless 2-SMD package configuration, suitable for automated assembly processes. Its equivalent series resistance (ESR) is specified at 60 kOhms, ensuring stable oscillation characteristics within low-power circuits.

Feature Summary

• Leadless two-terminal surface mount design facilitates compact PCB layout
• Optimized for low power consumption in battery-operated devices
• High frequency stability maintained across operating temperature ranges

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system clocks
• Portable communication devices

Procurement Notes

Verify the specific load capacitance requirement of 9 pF against the target oscillator circuit design to ensure accurate frequency generation. Confirm that the 60 kOhm ESR specification aligns with the host controller's drive level constraints. Ensure the leadless SMD footprint matches the designated board space and soldering profile requirements for reliable attachment.

Selection Notes

Select this component when a small form factor is required for 32.768 kHz timing references. The 9 pF load capacitance makes it suitable for circuits with minimal external capacitive loading. Consider the ±20 ppm tolerance if high precision is not critical, as tighter tolerances may require different part numbers from the manufacturer's portfolio.

Part Context

NDK produces a wide range of quartz crystal components, including resonators and oscillators, serving markets such as automotive, IoT, and mobile communications. The MU series represents their surface-mount crystal line, emphasizing miniaturization and reliability. This specific model fits into their broader catalog of timing solutions designed for cost-effective mass production.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 9 pF load capacitance, and 2-SMD leadless package dimensions. Verify ESR compatibility and frequency tolerance specifications before integration.
