CS06025-26M

Overview

The CS06025-26M is a surface-mount MHz crystal manufactured by NDK. It operates at a nominal frequency of 26 MHz with a fundamental oscillation mode. The component features a frequency tolerance of ±15 ppm and a frequency stability of ±20 ppm. It utilizes an 8 pF load capacitance and exhibits an equivalent series resistance (ESR) of 100 Ohms maximum. The device is housed in a compact 4-SMD, no-lead package designed for automated assembly processes.

Feature Summary

• Compact surface-mount design suitable for space-constrained mobile applications
• Fundamental oscillation mode operation for stable base clock generation
• Lead-free construction compliant with reflow soldering requirements

Applications

• Mobile phone handsets
• Bluetooth base clock frequency sources
• Mobile communications devices

Procurement Notes

Verify the specific ordering code suffix to confirm exact electrical parameters such as load capacitance and temperature characteristics, as custom specifications are available. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides official datasheets matching the manufacturer part number to avoid discrepancies in ESR or tolerance values.

Selection Notes

Select this component for applications requiring a 26 MHz fundamental frequency with strict size constraints. Verify that the host circuit can accommodate the 100 Ohm ESR limit. Ensure the PCB layout supports the 4-SMD footprint dimensions. Confirm that the operating temperature range meets the system requirements, as standard variants may differ from industrial grades.

Part Context

This part belongs to NDK's line of crystal units optimized for mobile communications. It shares design principles with other ultra-compact series like NX4025DA but differs in specific package dimensions and electrical parameters. It serves as a base clock source where small form factor and reliable performance are critical for portable electronic devices.

Replacement Considerations

Direct substitutes include NX4025DA-26M and CS16438-26M. Verify package compatibility and ESR differences before substitution. The NX4025DA offers similar functionality but may have different dimensional tolerances. Cross-reference load capacitance requirements to ensure circuit stability when replacing.
