SXT32418EE27-40.000M

Crystals Overview

The SXT32418EE27-40.000M is a parallel fundamental quartz crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 40.000 MHz with a frequency tolerance of ±15 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm.

Crystals Feature Summary

• Parallel fundamental quartz crystal design for stable oscillation
• Compact surface-mount form factor suitable for space-constrained PCB layouts

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing reference for communication interfaces
• Frequency control in consumer electronic devices

Crystals Procurement Notes

Verify the specific operating temperature range and stability requirements against application needs before procurement. Confirm that the 4-SMD no-lead package footprint matches the target PCB design. Ensure compatibility with reflow soldering profiles specified in the official datasheet to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 40 MHz frequency with ±15 ppm tolerance is required. The 18 pF load capacitance must match the circuit design. Consider the 40 Ohm ESR for drive level limitations. The small 3.2x2.5 mm package is ideal for high-density applications where standard through-hole crystals cannot fit.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT32418 series of surface-mount crystals. The series offers various frequencies and tolerances in a standardized small outline package. The EE27 suffix typically denotes specific packaging or tolerance characteristics within the product line, ensuring consistency across similar timing components.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 18 pF load capacitance, 40 Ohm ESR, and 4-SMD 3.2x2.5mm package. Verify pinout compatibility and thermal specifications. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions for supply chain flexibility.
