SXT14420BB07-25.000M

Crystals Overview

The SXT14420BB07-25.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precise timing applications. It operates at a nominal frequency of 25.000 MHz with a frequency tolerance of ±30 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SOJ plastic package with a 9.50 mm pitch, suitable for automated surface-mount assembly processes.

Crystals Feature Summary

• Plastic surface-mount design with four solder pads for secure attachment
• AT-cut resonator technology ensuring stable oscillation characteristics
• Standardized 9.50 mm pitch configuration compatible with standard pick-and-place equipment

Crystals Applications

• Microcontroller unit clock sources
• Communication interface timing references
• Measurement instrument internal clocks

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu Electronics documentation to confirm temperature range and tolerance grades. Ensure the ordering part number matches the required load capacitance and frequency stability specifications for the target application environment. Cross-reference the package dimensions with PCB footprint libraries to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required with moderate stability requirements. The 20 pF load capacitance must align with the host circuit's design parameters to ensure proper oscillation. Consider the ±30 ppm tolerance sufficient for general digital logic timing where higher precision is not mandated. Evaluate the 4-SOJ package size against available board space constraints.

Crystals Part Context

This part belongs to the SXT144 series of plastic surface-mount crystals from Suntsu Electronics. The series offers various frequency options and tolerance levels within a standardized small outline package format. The model designation indicates specific electrical parameters including the 25 MHz frequency and 20 pF load requirement, distinguishing it from other variants in the same product family.

Crystals Replacement Considerations

Direct substitutes include other SXT144 series parts with identical 25 MHz frequency and 20 pF load capacitance but different tolerance or temperature ratings, provided the system allows for adjusted stability margins. Verify pinout compatibility and package dimensions before substituting.
