STDCZS1-25M

Overview

STDCZS1-25M is a surface-mount quartz crystal resonator manufactured by NDK. It operates at a fundamental frequency of 25 MHz with a load capacitance of 8 pF. The component features a frequency tolerance and stability of ±15 ppm, ensuring precise timing performance. It utilizes a 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.60 mm. The device supports a base harmonic operating mode and has an equivalent series resistance (ESR) of 50 Ohms. It is rated for an operating temperature range of -10°C to +75°C.

Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package
• Fundamental oscillation mode for stable signal generation
• High frequency stability and tolerance specifications

Applications

• General-purpose timing circuits requiring 25 MHz reference
• Embedded systems and microcontroller clock sources
• Consumer electronics with standard temperature requirements

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as variations may exist between tape-and-reel, cut tape, or Digi-Reel formats. Confirm that the required operating temperature range of -10°C to +75°C aligns with the application environment, as this part does not support extended automotive-grade temperatures. Ensure the PCB footprint matches the 3.20 mm x 2.50 mm dimensions and 0.60 mm height constraints to avoid mechanical interference during assembly.

Selection Notes

Select this component when a 25 MHz fundamental frequency with ±15 ppm stability is required for commercial-grade applications. The 8 pF load capacitance must match the oscillator circuit design. Consider alternative parts if the application demands wider temperature ranges, such as -40°C to +125°C, or tighter frequency tolerances. The 50 Ohm ESR value should be compatible with the driving circuit's power requirements.

Part Context

The STDCZS1-25M belongs to NDK's NX3225SA series of surface-mount crystals. This series is designed for general electronic equipment where moderate size and reliable performance are prioritized. The part shares physical dimensions with other variants in the family but differs in electrical parameters such as frequency and temperature rating. It represents a standard solution for cost-sensitive consumer and industrial designs.

Replacement Considerations

CS14517-25M is a confirmed substitute part number from the same manufacturer with identical electrical characteristics.
