SXT22418FE27-25.000M

Crystals Overview

The SXT22418FE27-25.000M is a surface-mount crystal oscillator from Suntsu Electronics, operating at a fundamental frequency of 25 MHz. It features an 18 pF load capacitance and a series resistance of 80 Ohms. The component provides a frequency tolerance of ±10 ppm and a frequency stability of ±15 ppm across the specified temperature range. It utilizes a 4-SMD, no-lead package with dimensions of 2.0 mm x 1.25 mm. The device supports standard SMT assembly processes.

Crystals Feature Summary

• Compact 2012 (3225 equivalent footprint) 4-pad surface mount design for high-density PCB layouts
• High frequency stability with ±15 ppm total frequency deviation over the operating temperature range
• Robust anti-interference capability provided by the additional ground pad structure compared to standard 2-pad variants

Crystals Applications

• Industrial wireless gateways and communication modules
• PCMCIA interface devices requiring precise timing references
• Bluetooth and WiFi modem circuits
• Industrial control systems and PLCs

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure the correct temperature range and frequency tolerance match the design requirements. Confirm that the 4-pad package orientation aligns with the PCB footprint silkscreen and copper pad layout to prevent soldering defects during automated placement.

Crystals Selection Notes

Select this component when space constraints require a small 2012 footprint but higher electromagnetic interference immunity than standard 2-pad crystals. Ensure the circuit design accounts for the 18 pF load capacitance and 80 Ohm ESR to guarantee oscillation startup and maintain the specified ±10 ppm accuracy.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic packaged crystals. The series is characterized by its 4-pad configuration, which enhances mechanical stability and electrical performance in demanding environments. It serves as a critical timing element for digital logic and communication interfaces where size and precision are paramount.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz, 18 pF, 4-pad SMD crystals from manufacturers such as NDK or ECS, provided they meet the same 2.0x1.25mm package dimensions and 80 Ohm ESR specifications. Verify pin compatibility and thermal characteristics before substitution.
