MU00524-32.768K

Overview

The MU00524-32.768K is a surface-mount quartz crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 7 pF. The component features an equivalent series resistance (ESR) of 100 kOhms and is housed in a compact 2-SMD, No Lead package measuring 3.20mm x 1.50mm x 0.90mm maximum height. Designed for automotive applications, it meets the AEC-Q200 qualification standard and supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Compact 3.2mm x 1.5mm SMD footprint
• Wide temperature operation from -40°C to +85°C

Applications

• Automotive electronic systems
• Real-time clock circuits
• Low-frequency timing references

Procurement Notes

Verify the specific load capacitance requirement against the target oscillator circuit design, as this component specifies 7 pF. Confirm that the 100 kOhm ESR value aligns with the host controller's drive level constraints. Ensure the AEC-Q200 qualification status meets the specific automotive grade requirements of the end application before finalizing procurement.

Selection Notes

Select this component when a small form factor is required for low-frequency timing in automotive environments. The 3.2mm x 1.5mm size is suitable for space-constrained PCB layouts. The high ESR of 100 kOhms is typical for tuning fork crystals and requires compatible oscillator circuitry. Verify compatibility with the system's thermal profile given the -40°C to +85°C operating range.

Part Context

This part belongs to NDK's NX3215SA series of surface-mount tuning fork crystals. The series is characterized by its small physical dimensions and suitability for automotive-grade applications requiring strict reliability standards. NDK utilizes proprietary artificial crystal cultivation technology to ensure frequency stability and quality across its product line.

Replacement Considerations

Direct substitutes within the same series include MU00525-32.768K (6pF load) and MU00527-32.768K (6pF load, 80kOhm ESR). When replacing, verify that the load capacitance and ESR differences do not impact the oscillator circuit's startup time or frequency accuracy.
