SXT22422BA16-12.288M

Crystals Overview

The SXT22422BA16-12.288M is a 12.288 MHz AT-cut fundamental mode quartz crystal oscillator manufactured by Suntsu Electronics, Inc. It features a compact 2520 (2.5mm x 2.0mm) surface-mount package with four solder pads for enhanced grounding and EMI shielding. The component operates within an industrial temperature range of -40°C to +85°C, maintaining a frequency stability of ±30 ppm across the full range. It utilizes a standard load capacitance of 22 pF and exhibits a maximum equivalent series resistance (ESR) of 100 ohms at this frequency. The device is designed for low power consumption with a drive level not exceeding 100 μW.

Crystals Feature Summary

• Four-pad ceramic surface-mount design provides superior electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance ensures simple circuit startup without requiring additional matching inductors.
• Industrial-grade thermal stability maintains frequency accuracy across wide environmental temperature variations.

Crystals Applications

• Bluetooth Low Energy (BLE) wireless communication modules
• Short-range wireless positioning tags and IoT devices
• PCMCIA cards and high-density industrial control systems

Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm tolerance and temperature range specifications. Ensure the ordering part number matches the required load capacitance and frequency stability for your RF design. Confirm the package type is the 4-pad variant if EMI performance is critical. Request manufacturer documentation to validate authenticity and batch consistency before integration into production.

Crystals Selection Notes

Select this component when board space is constrained but electromagnetic compatibility is a priority due to its grounded four-pad structure. It is suitable for applications requiring stable timing in harsh environments where standard consumer-grade crystals may drift. Consider the 100 ohm ESR limit when designing the oscillator circuit to ensure reliable startup under all operating conditions.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series is characterized by small form factors and robust construction suitable for demanding electronic applications. It serves as a timing reference for microcontrollers and RF transceivers in portable and industrial equipment.

Crystals Replacement Considerations

Compatible substitutes include other 2520 4-pad crystals from Suntsu such as the SXT22422AA16 or SXT22422CB16 series, provided they match the 12.288 MHz frequency, 22 pF load capacitance, and 100 ohm ESR requirements.
