STDCSF4-12M

Overview

STDCSF4-12M is a surface-mount crystal oscillator manufactured by NDK. It operates at a nominal frequency of 12 MHz with a load capacitance of 8 pF. The component features an equivalent series resistance (ESR) of 80 Ohms and supports fundamental mode operation. Designed for reliability, it meets AEC-Q200 automotive standards and offers a frequency tolerance of ±20 ppm. The device utilizes a compact 2-SMD no-lead package, suitable for space-constrained applications requiring stable clock signals.

Feature Summary

• Compliant with AEC-Q200 automotive qualification standards for enhanced reliability
• Fundamental mode operation ensures stable oscillation characteristics
• Compact 2-SMD no-lead package design facilitates automated surface-mount assembly

Applications

• Automotive electronic systems requiring certified timing components
• Embedded microcontroller clock generation circuits
• Communication interface modules needing precise frequency references

Procurement Notes

Verify the specific suffix codes against official NDK documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when automotive-grade reliability is mandatory for the application. The 80 Ohm ESR value must align with the oscillator circuit's drive level requirements to prevent overdriving. Consider the 2-SMD footprint constraints during PCB layout planning. Verify that the ±20 ppm tolerance meets the system's overall frequency accuracy budget alongside other clock sources.

Part Context

This crystal belongs to NDK's standard SMD crystal lineup, designed for general-purpose and automotive applications. It complements larger packages like NX3225SA by offering a smaller form factor while maintaining robust performance metrics. The STDCSF4 series represents a balance between size reduction and electrical stability for modern compact electronics.

Replacement Considerations

Direct substitutes include CS15186-12M and STDCQS1-12M from NDK, which share similar 12 MHz frequencies but differ in package type and temperature range. Verify pin compatibility and electrical parameters such as ESR and load capacitance before swapping. Alternative manufacturers may offer functionally equivalent crystals, but automotive certification equivalence must be confirmed separately.
