CS05497-26M

Overview

The CS05497-26M is a quartz crystal unit manufactured by NDK, designed for surface-mount applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 6 pF. The component exhibits a frequency tolerance and stability of ±15 ppm. Its equivalent series resistance (ESR) is specified at 60 Ohms. The device utilizes a 4-SMD, no-lead package with dimensions of 3.20mm in length and 2.50mm in width. It supports a standard operating temperature range from -40°C to +85°C.

Feature Summary

• Provides precise timing signals via fundamental mode quartz resonance
• Designed for compact surface-mount integration on printed circuit boards
• Ensures stable frequency performance within specified industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication interface circuits
• Industrial control systems requiring stable timing references

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to ordering, as manufacturing specifications may evolve. Confirm that the 6 pF load capacitance aligns with the target circuit design requirements. Ensure the 4-SMD footprint matches the intended PCB layout constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required for system synchronization. The 6 pF load capacitance dictates compatibility with specific oscillator circuit designs; verify this matches the host controller's input requirements. Consider the 60 Ohm ESR value for power consumption and drive level limitations. The -40°C to +85°C temperature range suits general industrial and commercial environments rather than extreme automotive or military conditions.

Part Context

This component belongs to the NX2520SA series of low-power consumption crystals from NDK. It shares the same 3.2x2.5 mm package form factor with other variants in the series, such as the CS14524-26M, but differs in electrical parameters like load capacitance. The series is characterized by small size and high reliability for consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 6 pF load capacitance and 4-SMD 3.2x2.5mm footprints. Verify ESR and frequency stability tolerances match the original design specifications. Alternative packages require mechanical redesign.
