SXT22418EC48-24.000M

Crystals Overview

The SXT22418EC48-24.000M is a 24 MHz AT-cut fundamental mode crystal oscillator manufactured by Suntsu Electronics, Inc. It features a 4-SMD, no-lead package with dimensions of 2.5mm x 2.0mm. The device operates within an industrial temperature range of -40°C to +85°C. Key electrical specifications include a frequency tolerance and stability of ±15ppm, a load capacitance of 18pF, and a maximum equivalent series resistance (ESR) of 60 Ohms at the 24 MHz frequency. The component utilizes a ceramic surface-mount design suitable for high-density PCB layouts.

Crystals Feature Summary

• Four-pad ceramic surface-mount design providing enhanced grounding and shielding capabilities compared to two-pin variants.
• AT-cut fundamental resonance mode ensuring stable oscillation without requiring additional matching inductors.
• Industrial-grade thermal performance validated across a wide operating temperature range from -40°C to +85°C.

Crystals Applications

• Bluetooth Low Energy (BLE) modules
• Short-range wireless communication devices
• PCMCIA cards and modems
• Industrial control systems with dense board layouts

Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact tolerance, temperature range, and load capacitance requirements. Ensure that the ordering information matches the intended application parameters, as minor variations in suffixes can alter electrical characteristics. Cross-reference the manufacturer's latest documentation to confirm current availability and compliance status before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic interference immunity is critical due to the four-pad grounded structure. The ±15ppm stability meets stringent requirements for 2.4GHz wireless protocols. Consider the 60 Ohm ESR limit during circuit design to ensure reliable startup conditions across the specified industrial temperature range.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic crystals. The series is characterized by small form factors and robust construction designed for demanding environments. Variants within the series differ primarily in frequency, tolerance grades, and specific load capacitance values while maintaining consistent physical dimensions and mounting styles.

Crystals Replacement Considerations

Direct substitutes must match the 2.5x2.0mm 4-pad package, 24MHz frequency, 18pF load capacitance, and ±15ppm stability. Verify that alternative components support the same -40°C to +85°C operating range and have comparable ESR specifications to ensure circuit compatibility.
