SXT2248EA27-25.000M

Crystals Overview

The SXT2248EA27-25.000M is a 25 MHz fundamental AT-cut crystal oscillator manufactured by Suntsu Electronics, Inc. It operates within the industrial temperature range of -40°C to +85°C and features a frequency stability of ±15 ppm. The component utilizes an 8 pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, no-lead package designed for surface-mount assembly. This device is engineered for high reliability in space-constrained electronic applications requiring precise timing signals.

Crystals Feature Summary

• Industrial-grade thermal stability across extended temperature ranges
• Compact four-terminal surface-mount footprint for dense PCB layouts
• Fundamental AT-cut resonator design for stable oscillation

Crystals Applications

• Bluetooth low energy communication modules
• Short-range wireless sensor networks
• Industrial control systems with high-density circuit boards

Crystals Procurement Notes

Verify the specific suffix EA27 against the manufacturer's official datasheet to confirm exact tolerance and temperature grade specifications. Ensure the ordering part number matches the required load capacitance and ESR values for the target circuit design. Cross-reference the package dimensions with the mechanical drawing to confirm compatibility with automated pick-and-place equipment and soldering profiles.

Crystals Selection Notes

Select this component when strict size constraints require a 2520 footprint alongside industrial temperature resilience. The ±15 ppm stability suits applications demanding tighter frequency accuracy than standard consumer-grade crystals. Consider the 80 Ohm ESR value during oscillator circuit design to ensure adequate phase margin and reliable startup conditions under varying load conditions.

Crystals Part Context

This model belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is characterized by its small form factor and robust construction suitable for harsh environments. The SXT2248 variant specifically denotes the 2520 package dimensions and four-terminal configuration, distinguishing it from two-terminal alternatives in the same family.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals in 4-SMD packages with matching 8 pF load capacitance and similar ESR ratings. Verify that alternative parts support the -40°C to +85°C operating range and maintain comparable frequency stability metrics to ensure system performance parity.
