SXT2248ED27-48.000M

Crystals Overview

The SXT2248ED27-48.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precision timing applications in compact electronic systems. Operating at a fundamental frequency of 48.000 MHz, this component utilizes an AT-cut quartz resonator housed in a standard 4-SMD, no-lead package with dimensions typical of the 2520 footprint. It features a load capacitance of 8 pF and a maximum equivalent series resistance (ESR) of 50 Ohms within its operational range. The device offers a nominal frequency tolerance of ±15 ppm and a total frequency stability of ±20 ppm across the specified industrial temperature range of -20°C to +70°C. These specifications ensure reliable clock signal generation for high-density circuit designs requiring minimal spatial allocation.

Crystals Feature Summary

• Four-terminal surface mount design provides enhanced grounding and electromagnetic interference shielding compared to two-pin alternatives.
• AT-cut fundamental resonance architecture simplifies oscillation circuit requirements without necessitating additional matching inductors.
• Industrial-grade thermal performance ensures stable operation within extended environmental temperature constraints.

Crystals Applications

• Bluetooth low energy (BLE) positioning tags and wireless communication modules
• PCMCIA cards and internal modem interfaces
• High-density industrial control systems and wearable electronics

Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to confirm exact electrical parameters, including load capacitance and stability ratings. Ensure that the procurement source provides authentic components with traceable documentation. Cross-reference the part number with current availability status, as inventory levels for specialized industrial crystals may fluctuate. Confirm that the supplied units match the required package type and pinout specifications for your PCB layout.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility demands superior shielding provided by a four-pad ground connection. Choose this model for applications requiring strict frequency stability within the industrial temperature range while maintaining low power consumption. Consider the 8 pF load capacitance compatibility with your microcontroller or RF transceiver input requirements before finalizing the design.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics, Inc. The series is engineered for wireless and industrial applications where small form factors and robust performance are critical. Variants within this family differ primarily in frequency, tolerance, and stability specifications, allowing designers to tailor timing solutions to specific project requirements without changing the physical footprint.

Crystals Replacement Considerations

Direct substitutes include other 48 MHz crystals in 4-SMD packages with compatible load capacitance and stability ratings. Verify that alternative parts support the same operating temperature range and ESR limits to ensure circuit reliability. Check for pin-compatible options if mechanical retention is a concern, though most 2520 footprints are standardized across manufacturers.
