STDCIC1-26M

Overview

The STDCIC1-26M is a surface-mount crystal resonator manufactured by NDK. It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF and an equivalent series resistance of 150 Ohms. The component features a frequency tolerance of ±10 ppm and stability of ±30 ppm across a temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 0.90mm maximum height, it supports base harmonic operation and complies with RoHS standards.

Feature Summary

• Compact 4-SMD surface-mount design for automated assembly
• High frequency accuracy with ±10 ppm initial tolerance
• Wide operating temperature range suitable for industrial environments
• Fundamental mode operation for stable signal generation

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators
• Consumer electronics timing circuits

Procurement Notes

Verify the specific suffix and packaging configuration against the official NDK datasheet before ordering. Confirm that the required frequency tolerance and load capacitance match the target circuit design. Ensure the supplier provides valid RoHS compliance documentation. Check for any obsolescence notices or lifecycle changes directly from the manufacturer. Validate the package dimensions against the PCB footprint requirements.

Selection Notes

Select this component when a 26 MHz reference with high precision is required in a small form factor. The 150 Ohm ESR must be compatible with the oscillator circuit's drive level constraints. Consider the -40°C to +85°C range if the application involves variable environmental conditions. Compare the 8pF load capacitance against the existing board trace capacitance to ensure frequency accuracy.

Part Context

This part belongs to NDK's STD-CRG/STD-CIS series of miniature crystal resonators. These components are designed for applications requiring high reliability and stability in space-constrained devices. NDK utilizes proprietary crystal growth technologies to achieve consistent performance across their product lines, particularly in automotive and industrial sectors.

Replacement Considerations

Direct substitutes include CS14518-26M and CS16438-26M from NDK, though they may differ in ESR or temperature range. Cross-manufacturer alternatives like Abracon ABM10-26.000MHZ-D30-T3 require verification of package dimensions and electrical parameters.
