SXT22421AA38-16.384M

Crystals Overview

The SXT22421AA38-16.384M is a surface-mount ceramic crystal oscillator from Suntsu Electronics, Inc., featuring a 2520 (2.5mm x 2.0mm) footprint with four solder pads. It operates at a fundamental frequency of 16.384 MHz with a load capacitance of 21 pF and an equivalent series resistance (ESR) of 100 Ohms. The component provides a frequency tolerance of ±50 ppm and maintains stability within the -40°C to +85°C temperature range.

Crystals Feature Summary

• Four-pad ceramic package design enhances electromagnetic interference immunity compared to standard two-pin variants.
• AT-cut fundamental resonance mode ensures simple circuit startup without additional matching inductors.
• Low first-year aging rate supports long-term frequency stability for low-power applications.

Crystals Applications

• Bluetooth and short-range wireless communication modules
• PCMCIA interface devices
• Industrial control systems with high-density PCB layouts

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official naming convention to confirm exact electrical parameters. Ensure the requested variant matches the required load capacitance and temperature grade for your application environment before finalizing orders.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but signal integrity demands superior grounding via a four-pad layout. It is suitable for designs requiring fundamental mode operation with moderate frequency precision across industrial temperature ranges.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade surface-mount crystals. The series utilizes ceramic packages to provide robust mechanical stability and improved noise performance over basic glass-sealed alternatives, targeting demanding embedded and wireless environments.

Crystals Replacement Considerations

Direct substitutes must match the 2520 footprint, 16.384 MHz frequency, 21pF load capacitance, and 100 Ohm ESR specifications. Verify pin compatibility and thermal characteristics before integration.
