SXT22421BB16-22.1184M

Crystals Overview

The SXT22421BB16-22.1184M is a surface-mount quartz crystal resonator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 22.1184 MHz with a frequency tolerance of ±30 ppm. The component features a load capacitance of 21 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, No Lead package configuration designed for automated surface mount technology assembly.

Crystals Feature Summary

• Four-terminal surface mount design providing enhanced electromagnetic interference shielding compared to two-pin variants
• AT-cut fundamental resonance mode ensuring stable oscillation characteristics across the operating temperature range
• Ceramic package construction supporting industrial-grade reliability standards

Crystals Applications

• Bluetooth low energy modules and wireless communication devices
• PCMCIA interface equipment and data transmission systems
• Industrial control boards requiring high-density layout solutions

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact frequency stability and temperature range specifications. Ensure that the 4-SMD footprint matches the target PCB land pattern dimensions precisely. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement authorization.

Crystals Selection Notes

Select this component when strict spatial constraints require a 2520 form factor alongside superior noise immunity provided by four-pad grounding. The 22.1184 MHz frequency is suitable for specific clocking requirements in wireless protocols. Evaluate the ±30 ppm tolerance against system synchronization needs before implementation.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series emphasizes compact packaging with integrated ground pads to mitigate radio frequency interference in dense electronic assemblies. It serves as a timing reference for microcontrollers and RF transceivers in portable and industrial applications.

Crystals Replacement Considerations

Cross-reference alternative suppliers offering identical 22.1184 MHz frequency, 21 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that substitute components meet the same ±30 ppm tolerance and 80 Ohm ESR specifications to maintain circuit performance integrity.
