STDCSF4-8M

Overview

STDCSF4-8M is a surface-mount crystal oscillator manufactured by NDK. It operates at a fundamental frequency of 8 MHz with a frequency tolerance of ±20 ppm. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 200 Ohms. It utilizes a 2-SMD, no-lead package with dimensions of 5.0 mm x 3.2 mm and a maximum height of 1.50 mm. The device supports fundamental mode operation and functions within a temperature range of -10°C to +70°C.

Feature Summary

• Provides stable 8 MHz timing reference for digital circuits
• Compact 2-SMD surface-mount design for automated assembly
• Fundamental mode operation ensures precise frequency control

Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Procurement Notes

Verify the specific ordering suffix and packaging configuration required for your production line. Confirm that the 200 Ohm ESR limit aligns with your circuit design requirements. Ensure compatibility with the specified 8 pF load capacitance in your oscillator circuit layout. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a compact 8 MHz fundamental crystal is required for space-constrained designs. The 200 Ohm ESR specification suits standard oscillator circuits without excessive drive level sensitivity. Consider the -10°C to +70°C operating range against your application's thermal environment. The 2-SMD footprint facilitates high-volume surface mount technology integration.

Part Context

This part belongs to NDK's STDCSF4 series of surface-mount crystals. It shares the same physical footprint and electrical characteristics as other variants in the series, differing primarily in nominal frequency. The series is designed for general-purpose timing applications requiring reliable performance in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include STDCSF4-7.5M for lower frequency needs. Other NDK models in the NX5032GA or similar series may offer alternative specifications. Verify pinout and electrical parameters before cross-referencing with competitor components.
