SXT22421AA16-22.1184M

Crystals Overview

The SXT22421AA16-22.1184M is a surface-mount crystal resonator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 22.1184 MHz with a frequency tolerance of ±50 ppm. The component features a load capacitance of 21 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a ceramic package in a 4-SMD, no-lead form factor, designed for industrial-grade applications requiring stable timing signals.

Crystals Feature Summary

• AT-cut fundamental resonance design ensures reliable oscillation start-up without additional matching components.
• Four-pad surface mount configuration provides enhanced grounding and electromagnetic interference shielding compared to two-pin variants.
• Ceramic encapsulation supports operation within specified industrial temperature ranges for consistent performance.

Crystals Applications

• Bluetooth and short-range wireless communication modules
• PCMCIA interface devices
• Industrial control systems and modems

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm temperature range and tolerance grades. Ensure the ordering part number matches the required load capacitance and ESR specifications for the target circuit design. Confirm RoHS compliance status through current manufacturer declarations prior to procurement.

Crystals Selection Notes

Select this component when a compact 2520 footprint is required alongside superior noise immunity provided by the four-terminal ground structure. The AT-cut base frequency offers simpler circuit design compared to overtone modes. Evaluate the ±50 ppm tolerance against system clock accuracy requirements before finalizing the selection.

Crystals Part Context

This model belongs to the SXT224 series, which comprises industrial-grade ceramic surface-mount crystals. The series is characterized by small form factors and multi-pad designs intended for high-density PCB layouts. It serves as a timing reference solution for portable and embedded electronic devices.

Crystals Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative parts match the 22.1184 MHz frequency, 21 pF load capacitance, and 80 Ohm ESR constraints. Ensure physical dimensions and pin configurations are compatible with existing footprints.
