STDCSU2-12M

Overview

STDCSU2-12M is a surface-mount MHz crystal manufactured by NDK. It operates at a nominal frequency of 12 MHz with a frequency tolerance of ±50ppm and stability of ±50ppm. The component features an 8pF load capacitance and 150 Ohms equivalent series resistance. It utilizes a 2-SMD, no lead package measuring 5.00mm x 3.20mm with a maximum height of 1.50mm. Designed for fundamental mode operation, it supports a commercial temperature range of -10°C to +70°C.

Feature Summary

• Fundamental mode quartz crystal resonator
• Compact 2-SMD surface mount footprint
• RoHS compliant construction

Applications

• General purpose clock signal generation
• Microcontroller system timing
• Consumer electronic circuitry

Procurement Notes

Verify the specific frequency tolerance requirement against the ±50ppm specification before integration. Confirm that the 150 Ohms ESR aligns with the oscillator circuit design parameters. Ensure the operating temperature range meets the environmental conditions of the target application. Cross-reference the 2-SMD package dimensions with the PCB layout constraints.

Selection Notes

Select this component when a standard 12 MHz reference is required in a compact form factor. The ±50ppm tolerance suits applications where high precision is not critical. Consider the 150 Ohms ESR value for oscillator startup reliability. The 2-pin SMD package offers space efficiency compared to larger through-hole alternatives.

Part Context

This part belongs to NDK's portfolio of surface-mount crystals. It provides a basic timing solution for digital circuits. The manufacturer specializes in quartz devices for various electronics sectors. This specific model represents a standard commercial-grade option within their broader component lineup.

Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 8pF load capacitance, and 2-SMD package dimensions. Verify equivalent ESR and tolerance specifications. Check compatibility with the host oscillator circuit requirements.
