SXT2247AA27-25.000M

Crystals Overview

The SXT2247AA27-25.000M is a 25 MHz fundamental AT-cut crystal oscillator manufactured by Suntsu Electronics, Inc. It features a frequency stability of ±50ppm and operates within the industrial temperature range of -40°C to +85°C. The component utilizes a 7pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms at this specific frequency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm, designed for surface-mount applications requiring high reliability and low profile.

Crystals Feature Summary

• Industrial-grade temperature stability ensuring consistent performance across wide thermal variations
• Four-terminal SMD design providing enhanced electromagnetic interference shielding compared to two-pin variants
• Fundamental AT-cut resonance mechanism simplifying circuit matching requirements

Crystals Applications

• Bluetooth Low Energy (BLE) modules and wireless positioning tags
• PCMCIA cards and short-range communication modems
• High-density industrial control systems and wearable devices

Crystals Procurement Notes

Verify that the specific part number matches the required frequency tolerance and load capacitance for your circuit design. Confirm the package orientation and pad layout compatibility with your PCB footprint. Ensure the supplier provides official datasheets to validate the industrial temperature rating and ESR specifications before finalizing orders.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic immunity is critical. The four-pad configuration offers superior grounding compared to standard two-pin crystals, reducing radiated emissions in sensitive RF environments. Consider the ±50ppm stability sufficient for general-purpose clocking where tighter tolerances are not mandated by the protocol.

Crystals Part Context

This model belongs to the SXT224 series of ceramic SMD crystals from Suntsu Electronics. The series is characterized by its small form factor and robust construction suitable for demanding electronic applications. Variations within the series differ primarily in frequency, tolerance, and load capacitance while maintaining the same physical package and basic electrical architecture.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants such as SXT2247AA27-24.000M or SXT2247AA27-12.000M if different frequencies are acceptable. Cross-brand replacements must match the 4-SMD no-lead package, 25MHz frequency, 7pF load capacitance, and 80 Ohm ESR to ensure circuit compatibility.
