MU01089-32.768K

Overview

The MU01089-32.768K is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 32.768 kHz, designed for precise timekeeping applications. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 80 kOhms. It utilizes a 2-SMD, No Lead package configuration, ensuring compact integration into electronic circuits. This specific model provides stable oscillation characteristics suitable for low-power digital systems requiring accurate clock signals.

Feature Summary

• Compact 2-SMD, No Lead package design for space-constrained PCB layouts
• Optimized load capacitance of 6 pF for standard oscillator circuit compatibility
• High stability quartz construction for reliable long-term frequency performance

Applications

• Real-time clock modules in consumer electronics
• Microcontroller system clock sources
• Portable battery-powered devices requiring low power consumption

Procurement Notes

Verify the exact load capacitance requirements of your target oscillator circuit against the component's specified 6 pF rating to ensure proper frequency accuracy. Confirm that the 2-SMD, No Lead package dimensions align with your board space constraints and pick-and-place equipment capabilities. Ensure that the ESR specification meets the driving level limits of your host IC to prevent over-driving the crystal element.

Selection Notes

Select this component when a small form factor is critical for the application design. The 6 pF load capacitance makes it suitable for modern microcontrollers with internal capacitors or minimal external components. Consider the 80 kOhm ESR if the driving circuit has limited output current capability. Evaluate the thermal stability requirements of the end product to ensure the standard temperature range meets operational needs.

Part Context

NDK is a specialized manufacturer of crystalline quartz products with extensive experience in precision timing components. The MU01089 series represents their surface-mount crystal offerings, focusing on miniaturization and reliability. This part number specifically denotes the 32.768 kHz variant within their SMD portfolio, targeting the widespread demand for real-time clock frequencies in portable and embedded electronics.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 6 pF load capacitance, and 2-SMD package type. Verify ESR values near 80 kOhms to maintain circuit stability. Check manufacturer-specific mounting recommendations as soldering profiles may vary between suppliers even for identical electrical specifications.
