SXT32421CC27-22.1184M

Crystals Overview

The SXT32421CC27-22.1184M is a surface-mount crystal oscillator from Suntsu Electronics, Inc., designed for precision timing applications. It operates at a fundamental frequency of 22.1184 MHz with a load capacitance of 21pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance and stability of ±25ppm across the specified operating temperature range. Housed in a compact 3225 package with four solder pads, it supports automated SMT assembly via tape and reel packaging.

Crystals Feature Summary

• Four-pad ceramic surface-mount design enhances grounding and electromagnetic interference resistance compared to standard two-pad configurations.
• Fundamental mode operation ensures stable oscillation characteristics suitable for high-density circuit layouts.

Crystals Applications

• Industrial wireless gateways and communication modules
• PCMCIA interface devices requiring precise clock signals
• Bluetooth and WiFi module integration

Crystals Procurement Notes

Verify that the specific part number suffix matches the required load capacitance and frequency tolerance specifications for your application. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with standard SMT reflow profiles during assembly planning.

Crystals Selection Notes

Select this component when a 3225 footprint is required alongside improved noise immunity provided by the four-pad structure. Consider the ±25ppm stability requirement against system timing constraints. Evaluate the 21pF load capacitance to ensure proper matching with the host microcontroller or oscillator circuit input requirements.

Crystals Part Context

This model belongs to the SXT324 series, which represents industrial-grade crystals in a small form factor. The series is characterized by its ability to support high-frequency stability within constrained board spaces, making it a common choice for modern portable and embedded electronic systems.

Crystals Replacement Considerations

Direct substitutes must match the 22.1184 MHz frequency, 21pF load capacitance, and 3225 package dimensions. Verify that alternative components offer comparable ESR values and thermal stability ranges to maintain signal integrity in existing designs.
