Crystals Overview

The SXT14418FA16-8.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precise frequency generation in electronic circuits. It operates at a nominal frequency of 8.000 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SOJ package with a 9.50 mm pitch, suitable for automated assembly processes. This device provides stable clock signals for microcontrollers and communication interfaces.

Crystals Feature Summary

• Provides high-frequency stability with ±10 ppm tolerance for precision timing applications
• Utilizes a compact 4-pin surface-mount SOJ package for efficient PCB layout
• Engineered for low equivalent series resistance to ensure reliable oscillation startup

Crystals Applications

• Microcontroller system clock sources
• Communication interface timing references
• Industrial measurement instrument clocks

Crystals Procurement Notes

Verify the specific suffix FA16 against the manufacturer's datasheet to confirm the exact temperature range and aging specifications. Ensure the load capacitance requirement of your circuit matches the 18 pF specification to prevent frequency deviation. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a stable 8 MHz reference is required with tight frequency accuracy. The 18 pF load capacitance suits standard MCU designs without external trimming. Consider the 100 Ohm ESR for drive level sensitivity. Evaluate the 4-SOJ form factor against available board space. Compare against ±25 ppm variants if cost is critical and precision is less demanding.

Crystals Part Context

This part belongs to the SXT144 series of plastic-sealed surface-mount crystals from Suntsu Electronics. The series offers various frequency options ranging from 3.579 MHz to 27 MHz. Different suffixes indicate variations in load capacitance, tolerance, and temperature ranges. The SXT14418FA16 variant specifically targets industrial-grade reliability with narrow frequency drift characteristics.

Crystals Replacement Considerations

Direct substitutes include other 8 MHz crystals with identical 18 pF load capacitance and 4-SOJ packaging. Verify that alternative parts meet the ±10 ppm tolerance and 100 Ohm ESR requirements. Check if competitor components support the same operating temperature range. Ensure pin pitch compatibility for seamless replacement without PCB redesign.
