SXT22422BA27-14.7456M

Crystals Overview

The SXT22422BA27-14.7456M is a ceramic surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 14.7456 MHz with a nominal load capacitance of 22 pF and an equivalent series resistance (ESR) of 120 Ohms. The component utilizes a 4-SMD, no-lead package with physical dimensions of 2.50 mm x 2.00 mm. It provides a frequency tolerance of ±30 ppm and is designed for industrial applications.

Crystals Feature Summary

• Four-pad surface mount design providing enhanced electromagnetic interference shielding compared to two-pin variants
• Industrial-grade temperature range capability ensuring stability in demanding environments
• Fundamental AT-cut quartz resonator architecture simplifying circuit startup requirements

Crystals Applications

• Bluetooth low energy positioning tags
• Short-range wireless communication devices
• PCMCIA cards and modems
• High-density industrial control systems

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical tolerances and temperature ranges. Ensure the 4-SMD no-lead package footprint matches the target PCB layout. Confirm that the 120 Ohm ESR aligns with the oscillator circuit design specifications for reliable startup.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility is critical. The four-terminal configuration offers superior grounding compared to standard two-lead crystals. Consider the ±30 ppm tolerance sufficient for general wireless protocols where tighter precision is not mandated.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic SMD crystals. The series is characterized by small form factors suitable for portable electronics. Variations within the series differ primarily in load capacitance, frequency tolerance, and operating temperature limits while maintaining consistent physical dimensions.

Crystals Replacement Considerations

Substitute parts must match the 2.50mm x 2.00mm footprint and 14.7456 MHz frequency. Verify that alternative components support 22pF load capacitance and similar ESR values to ensure circuit compatibility without redesign.
