MU00526-32.768K

Overview

The MU00526-32.768K is a surface-mount tuning fork crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 6 pF and an equivalent series resistance of 70 kOhms. The component features a 2-SMD, no-lead package measuring 3.20 mm in length, 1.50 mm in width, and a maximum height of 0.90 mm. It belongs to the NX3215SA series and supports base harmonic operation within a temperature range of -40°C to 85°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q200 standards
• Miniature 3.2mm x 1.5mm SMD footprint for space-constrained designs
• High stability tuning fork architecture optimized for low-power clock applications

Applications

• Real-time clock circuits in automotive infotainment systems
• Timekeeping modules in consumer electronic devices
• Low-frequency reference sources in IoT sensor nodes

Procurement Notes

Verify that the specific part number MU00526-32.768K matches the required load capacitance and tolerance specifications for the target circuit design. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure that the supplier provides valid traceability documentation and quality certificates consistent with automotive-grade manufacturing requirements.

Selection Notes

Select this component when a compact 32.768 kHz timing source is required for automotive or industrial environments. The 6 pF load capacitance must align with the oscillator circuit's input capacitance to ensure accurate frequency generation. Consider the 70 kOhm ESR limits when designing the drive level constraints to prevent over-driving the crystal element.

Part Context

This component is part of the NX3215SA series, which focuses on miniature tuning fork crystals designed for high-volume production. NDK utilizes its proprietary artificial crystal cultivation technology to maintain frequency stability across wide temperature ranges. The series supports both standard commercial and automotive-grade variants to meet diverse market demands.

Replacement Considerations

Direct substitutes include the MU00525-32.768K from the same manufacturer, which shares identical electrical parameters and package dimensions. Cross-vendor replacements require verification of matching load capacitance, ESR, and AEC-Q200 certification status.
