SXT22420DD17-50.000M

Crystals Overview

The SXT22420DD17-50.000M is a 50 MHz AT-cut fundamental frequency crystal oscillator manufactured by Suntsu Electronics, Inc. It features a 4-SMD, no lead package with dimensions of 2.5mm x 2.0mm. The component operates within a temperature range of -10°C to +70°C and maintains a frequency stability of ±20ppm. Key electrical specifications include a load capacitance of 20pF and an equivalent series resistance (ESR) of 50 Ohms. This industrial-grade device is designed for surface-mount applications requiring precise timing in compact electronic systems.

Crystals Feature Summary

• Four-pad ceramic SMD design provides enhanced grounding and shielding capabilities compared to two-pin alternatives.
• AT-cut fundamental resonance architecture simplifies circuit design by eliminating the need for additional matching inductors.

Crystals Applications

• Bluetooth low energy (BLE) positioning tags
• Zigbee short-range wireless communication devices
• PCMCIA cards and internal modems

Crystals Procurement Notes

Verify the specific suffix 'DD17' against the manufacturer's official datasheet to confirm the exact operating temperature range (-10°C to +70°C) and tolerance class (+/- 20ppm). Ensure the required load capacitance matches the target circuit design. Confirm RoHS compliance status directly with the supplier or through the latest product documentation before finalizing procurement orders.

Crystals Selection Notes

Select this component when board space is limited to a 2.5x2.0mm footprint but electromagnetic interference immunity is critical. The four-terminal structure offers superior EMI performance over standard two-lead variants. Choose this model for industrial environments where moderate temperature stability is sufficient, avoiding higher-cost wide-temperature options unless necessary.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade crystals from Suntsu Electronics. The series utilizes a ceramic package suitable for high-density PCB layouts. The 'SXT224' designation indicates the physical form factor, while the alphanumeric suffixes define the specific electrical characteristics such as frequency, tolerance, and temperature rating.

Crystals Replacement Considerations

Direct substitutes must match the 2.5x2.0mm 4-SMD package, 50MHz frequency, and 20pF load capacitance. Verify that alternative components support the same -10°C to +70°C operating range and similar ESR values to ensure circuit compatibility without redesign.
