STDCIX1-37.4M

Overview

STDCIX1-37.4M is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 37.4 MHz with a frequency tolerance of ±10 ppm and stability of ±10 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 2.50 mm x 2.00 mm and a maximum height of 0.65 mm. Designed for base mode operation, it supports industrial temperature ranges and meets RoHS3 compliance standards.

Feature Summary

• Compact 4-SMD no-lead surface mount package suitable for automated assembly
• High frequency stability and tight tolerance for precise timing applications
• Compliant with RoHS3 environmental directives

Applications

• Digital signal processing circuits requiring stable clock references
• Communication modules operating at specific RF frequencies
• Microcontroller-based systems needing precise timing synchronization

Procurement Notes

Verify the exact part number STDCIX1-37.4M against official NDK documentation to ensure compatibility with design specifications. Confirm that the 4-SMD no-lead footprint matches the PCB layout constraints. Check for RoHS3 compliance requirements if applicable to the target market. Ensure the load capacitance of 8pF aligns with the oscillator circuit design parameters before procurement.

Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with high precision. The 100 Ohm ESR must be compatible with the driving circuit's oscillation conditions. Consider the small 2.5x2.0 mm package size for space-constrained designs. Verify thermal performance within the specified operating range for the intended application environment.

Part Context

This crystal belongs to NDK's portfolio of surface-mount resonators, which are widely used in mobile communications, automotive electronics, and IoT devices. NDK leverages its expertise in artificial quartz cultivation to provide products with high frequency stability and reliability across various industrial and consumer applications.

Replacement Considerations

No publicly confirmed substitute part numbers are available for STDCIX1-37.4M. Direct replacement requires matching the 37.4 MHz frequency, 8pF load capacitance, 100 Ohm ESR, and 4-SMD no-lead package dimensions precisely.
