SXT83418FB38-25.000M

Crystals Overview

The SXT83418FB38-25.000M is a 25 MHz fundamental mode quartz crystal manufactured by Suntsu Electronics, Inc. It operates within the -20°C to +70°C temperature range and features a frequency stability of ±10 ppm and tolerance of ±25 ppm. The component utilizes an 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. It is housed in a 4-SOJ surface-mount package with a 5.50 mm pitch, designed for reliable timing applications requiring precise frequency control.

Crystals Feature Summary

• Fundamental resonance mode operation ensures stable frequency generation
• Surface-mount SOJ package design facilitates automated assembly processes
• Precision frequency stability supports high-reliability timing requirements

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix FB38 against official Suntsu documentation to confirm the exact ESR value and package dimensions. Ensure the operating environment remains within the specified -20°C to +70°C range to maintain the stated ±10 ppm stability. Cross-reference the 18 pF load capacitance requirement with the target circuit design to prevent frequency deviation issues during implementation.

Crystals Selection Notes

Select this component when a fundamental mode crystal with moderate stability is required for space-constrained designs. The 4-SOJ package offers a balance between thermal performance and board space efficiency compared to larger through-hole alternatives. Consider the 60 Ohm ESR limit when designing oscillator circuits to ensure proper startup conditions and sustained oscillation without excessive loading on the driving stage.

Crystals Part Context

This part belongs to the Suntsu SXT834 series of surface-mount crystals. The series provides various frequency options and package configurations tailored for consumer electronics and industrial equipment. The SXT83418FB38 variant specifically targets applications needing 25 MHz timing with standard reliability levels, distinguishing it from higher-stability or wider-temperature variants within the broader product line.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz 4-SOJ crystals with matching 18 pF load capacitance and similar ESR specifications. Verify that alternative components support the same fundamental mode operation and meet the ±10 ppm stability requirement. Ensure pin compatibility and mechanical footprint alignment to avoid PCB redesign efforts during replacement.
