SXT22418CA17-50.000M

Crystals Overview

The SXT22418CA17-50.000M is a 50 MHz AT-cut fundamental frequency crystal oscillator manufactured by Suntsu Electronics, Inc. It features a 4-pad surface-mount package with no lead design, measuring 2.5mm x 2.0mm. The component operates within a -10°C to +70°C temperature range and maintains a frequency tolerance of ±25ppm at normal temperature. It utilizes an 18pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 50 Ohms. This industrial-grade device is designed for applications requiring stable timing in compact wireless and control systems.

Crystals Feature Summary

• Four-pad ceramic surface-mount design provides enhanced grounding and shielding capabilities compared to two-pin alternatives.
• AT-cut fundamental resonance ensures simple oscillation circuit requirements without the need for additional matching inductors.
• Compact 2520 footprint supports high-density board layouts while maintaining industrial reliability standards.

Crystals Applications

• Bluetooth and short-range wireless communication devices
• PCMCIA cards and modem modules
• Industrial control systems with dense PCB layouts

Crystals Procurement Notes

Verify the specific suffix against official Suntsu documentation to confirm exact temperature range and tolerance specifications. Ensure the ordering part number matches the required load capacitance and ESR limits for your target application. Cross-reference datasheet revisions to confirm compliance with current manufacturing standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a 2520 package but electromagnetic interference mitigation is critical. The four-pad structure offers superior noise immunity for 2.4GHz radio frequencies compared to standard two-terminal crystals. Consider the ±25ppm stability for Bluetooth and Zigbee protocols where precise frequency alignment is necessary for reliable data transmission.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series is characterized by its small form factor and robust construction suitable for harsh environments. The specific variant denotes a 50MHz output with standard commercial/industrial temperature ratings and defined electrical parameters for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes must match the 2520 footprint, 4-pad configuration, and 50MHz frequency. Verify that alternative components support the same 18pF load capacitance and meet or exceed the 50 Ohm ESR requirement. Ensure replacement parts offer comparable frequency stability and operating temperature ranges to maintain system performance.
