MU00528-32.768K

Overview

The MU00528-32.768K is a surface-mount tuning fork crystal manufactured by NDK, belonging to the NX2012SA series. 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 a 2-SMD, no-lead package measuring 2.0 mm in length, 1.2 mm in width, and 0.90 mm in maximum height. Designed for base mode operation, it supports a temperature range of -40°C to +85°C.

Feature Summary

• Compact 2.0x1.2mm SMD footprint suitable for space-constrained designs
• Tuning fork architecture optimized for low-power real-time clock applications
• Automotive-grade reliability compliant with AEC-Q200 standards

Applications

• Real-time clock circuits in automotive infotainment systems
• Timekeeping modules in consumer electronic devices
• Low-frequency reference sources for microcontroller units

Procurement Notes

Verify that the specific ordering suffix matches the required load capacitance and tolerance specifications for your circuit design. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure proper handling procedures are followed during assembly to maintain component integrity and electrical performance.

Selection Notes

Select this component when a small form factor is critical for the application layout. The 12.5 pF load capacitance requires matching oscillator circuit parameters to ensure accurate frequency generation. Consider the 80 kOhm ESR value when evaluating drive level sensitivity and startup time requirements within the target system.

Part Context

This part belongs to the NX2012SA series of ultra-small crystals from NDK. The series is characterized by its miniature dimensions and high stability, making it suitable for modern miniaturized electronics. NDK manufactures these components using proprietary artificial quartz crystal cultivation technology to ensure consistent quality and performance across production batches.

Replacement Considerations

Direct substitutes include other 32.768 kHz crystals in the 2.0x1.2mm package with identical 12.5 pF load capacitance. Verify that alternative parts meet the same AEC-Q200 qualification if automotive usage is intended. Check equivalent series resistance and operating temperature range compatibility before substitution.
