STDCSF6-8M

Overview

The STDCSF6-8M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 8.0000 MHz with a load capacitance of 8pF. The component features an equivalent series resistance (ESR) of 200 Ohms and a frequency tolerance of ±30ppm. It utilizes a 2-SMD, no lead package configuration.

Feature Summary

• Fundamental mode operation for stable oscillation
• Surface-mount design for automated assembly integration

Applications

• General electronic circuit timing references
• Microcontroller clock sources
• Consumer electronics signal generation

Procurement Notes

Verify the specific datasheet version for the STDCSF6-8M to confirm environmental ratings and soldering profiles. Ensure compatibility with the target circuit's load capacitance requirements. Check for RoHS compliance status in official documentation before finalizing procurement plans.

Selection Notes

Select this component when a low-cost, general-purpose 8MHz reference is required. The ±30ppm tolerance suits applications with relaxed frequency accuracy needs. Consider the 200 Ohm ESR value against the oscillator circuit's drive level constraints to ensure reliable startup.

Part Context

This part belongs to NDK's standard SMD crystal lineup, designed for cost-effective mass production. It complements higher-precision series like NX3225SA by offering basic timing functions in a compact footprint suitable for space-constrained consumer devices.

Replacement Considerations

Direct substitutes include other 8MHz 2-SMD crystals with matching 8pF load capacitance and similar ESR values. Verify pinout compatibility and physical dimensions before swapping with generic alternatives.
