STDCSI1-26M

Overview

STDCSI1-26M is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF. The component features a frequency tolerance of ±20 ppm and stability of ±30 ppm within an operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with dimensions of 1.2mm x 1.0mm and a maximum height of 0.4mm. The equivalent series resistance (ESR) is specified at 80 Ohms.

Feature Summary

• Provides stable frequency generation for digital circuits using quartz crystal technology
• Designed for surface-mount assembly to support automated PCB manufacturing processes
• Operates reliably across wide industrial temperature ranges for diverse environmental conditions

Applications

• Clock signal generation in microcontroller units
• Timing references for communication interface modules
