CS10694-25M

Overview

The CS10694-25M is a surface-mount crystal oscillator manufactured by NDK (Nihon Dempa Kogyo Co., Ltd.). It operates at a fundamental frequency of 25.0000 MHz with a load capacitance of 8 pF. The component features a frequency tolerance of ±10 ppm and an equivalent series resistance (ESR) of 80 Ohms maximum. It is housed in a compact 4-SMD, No Lead package suitable for automated assembly.

Feature Summary

• Surface-mount design for automated PCB assembly
• Fundamental mode crystal operation
• Standard 8 pF load capacitance compatibility

Applications

• General-purpose clock generation circuits
• Microcontroller system timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix codes against official NDK documentation to ensure exact electrical parameters and packaging specifications. Confirm that the 4-SMD footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a 25 MHz reference signal is required for embedded systems. Ensure the application circuit provides the specified 8 pF load capacitance to maintain the stated ±10 ppm frequency accuracy. Check ESR limits against oscillator circuit drive levels.

Part Context

This part belongs to NDK's standard SMD crystal lineup designed for consumer electronics and industrial applications. It serves as a passive frequency-determining element within resonant circuits, replacing through-hole variants in modern miniaturized designs.

Replacement Considerations

Consult NDK official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter equivalence if considering alternative manufacturers.
