SXT14420CA48-4.000M

Crystals Overview

The SXT14420CA48-4.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 4.000 MHz with a tolerance of ±25 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 150 Ohms. It is housed in a 4-SOJ package with a 9.50 mm pitch, designed for precise timing applications requiring stable frequency generation.

Crystals Feature Summary

• Provides stable frequency generation at 4.000 MHz
• Surface-mount design for automated assembly
• Low equivalent series resistance for efficient operation

Crystals Applications

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

Crystals Procurement Notes

Verify the specific suffix '4.000M' confirms the 4 MHz frequency variant. Ensure compatibility with the 4-SOJ 9.50mm pitch footprint on the PCB. Confirm that the ±25 ppm tolerance meets the system's timing requirements. Check for RoHS compliance status if required by project specifications.

Crystals Selection Notes

Select this component when a 4 MHz reference is needed with moderate stability. The 20pF load capacitance must match the circuit design. Consider the 150 Ohm ESR for drive level limitations. The SOJ package requires appropriate reflow soldering profiles to ensure joint integrity without damaging the crystal element.

Crystals Part Context

This part belongs to the SXT14420CA48 series from Suntsu Electronics, which offers various frequency options within the same physical package. The series provides standardized dimensions for easy integration into existing designs requiring different clock speeds while maintaining consistent board layout constraints.

Crystals Replacement Considerations

Direct substitutes include other 4 MHz crystals in 4-SOJ packages with matching 20pF load capacitance and similar ESR values. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with manufacturer cross-listings for exact electrical equivalence.
