SXT22420CA38-50.000M

Crystals Overview

The SXT22420CA38-50.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., operating at a fundamental frequency of 50.000 MHz. It features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 50 Ohms. The component utilizes a 4-SMD, no-lead package design, suitable for automated assembly processes. This specific model belongs to the SXT224 series, which is characterized by its compact form factor and industrial-grade reliability.

Crystals Feature Summary

• Four-pad ceramic SMD construction providing enhanced grounding and shielding capabilities compared to two-pin variants.
• Fundamental AT-cut resonator design ensuring stable oscillation with simplified circuit requirements.
• Industrial temperature range operation supporting robust performance in demanding environments.

Crystals Applications

• Bluetooth low energy (BLE) modules
• Short-range wireless communication devices
• PCMCIA cards and modems
• High-density industrial control systems

Crystals Procurement Notes

Verify the exact suffix 'CA38' against the manufacturer's current datasheet to confirm pinout compatibility and tolerance specifications. Ensure that the 4-SMD footprint matches the PCB land pattern precisely. Confirm that the 20pF load capacitance aligns with the host circuit's oscillator design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0mm footprint but electromagnetic interference immunity is critical. The four-terminal design offers superior noise rejection compared to standard two-terminal crystals. Consider the 50 Ohm ESR value to ensure proper drive level management within the target application circuit.

Crystals Part Context

This part belongs to the SXT224 series from Suntsu Electronics, designed for high-reliability timing applications. The series is engineered for small-form-factor electronics, offering a balance between miniaturization and electrical stability. It serves as a direct replacement for other 2520-sized crystals where improved shielding is required.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 20 pF load capacitance, and 4-SMD package dimensions. Verify that alternative components support the same industrial temperature range and have comparable ESR values to maintain circuit stability without redesigning the oscillator network.
