STDCSW2-24M

Overview

The STDCSW2-24M is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 24 MHz with a load capacitance of 10 pF. The component exhibits a frequency tolerance and stability of ±10 ppm and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm.

Feature Summary

• High-frequency stability for precise timing applications
• Compact surface-mount design for automated assembly

Applications

• Consumer electronics timing circuits
• Microcontroller clock sources
• Communication device oscillators

Procurement Notes

Verify the specific manufacturer datasheet to confirm RoHS compliance status and detailed electrical parameters prior to integration. Ensure the selected package variant matches the PCB footprint requirements exactly. Cross-reference the supplier's official documentation for any recent design changes or obsolescence notices associated with this part number.

Selection Notes

Select this component when a 24 MHz fundamental mode crystal is required with tight ±10 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit against the driving circuit capabilities. The 2.5x2.0 mm form factor suits space-constrained layouts compared to larger standard packages.

Part Context

This part belongs to NDK's portfolio of miniature crystal devices, leveraging the company's expertise in artificial quartz cultivation. NDK produces these components across global facilities, including plants in China, Malaysia, and the US, ensuring consistent quality for automotive and consumer markets.

Replacement Considerations

Direct substitutes include other 24 MHz SMD crystals with matching 10 pF load capacitance and similar physical dimensions. Verify that alternative parts meet the same ±10 ppm stability and 60 Ohm ESR specifications to ensure circuit compatibility.
