CS00445-26M

Overview

The CS00445-26M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 26.0000 MHz with a load capacitance of 10 pF. The component exhibits a frequency tolerance and stability of ±10 ppm, alongside an equivalent series resistance (ESR) of 100 Ohms. Designed for robust performance, it supports an operating temperature range from -40°C to +85°C. The device utilizes a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.35mm. It is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Integrates high-frequency stability with a compact surface-mount footprint for space-constrained designs
• Ensures reliable oscillation through low equivalent series resistance in a lead-free SMD configuration
• Supports wide industrial temperature ranges for consistent performance in diverse environmental conditions

Applications

• Mobile communication devices requiring precise timing signals
• Fixed radio communication equipment needing stable frequency references
• Office automation systems utilizing quartz crystal components
• Automotive electronics applications demanding high-reliability oscillators

Procurement Notes

Verify the specific part number CS00445-26M against official NDK documentation to confirm electrical parameters such as 10pF load capacitance and ±10ppm stability. Ensure compatibility with surface-mount assembly processes and check for RoHS compliance status relevant to your region. Confirm that the 4-SMD package dimensions align with your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 26 MHz fundamental mode crystal is required with tight ±10 ppm stability specifications. The 100 Ohm ESR and 10pF load capacitance must match the oscillator circuit design constraints. Consider the -40°C to +85°C operating range for industrial or automotive environments. The small 1.60mm x 1.20mm package size is suitable for dense surface-mount layouts where space is limited compared to larger crystal packages.
