SXT2247DB16-20.000M

Crystals Overview

The SXT2247DB16-20.000M is a 20 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 component operates within a temperature range of -40°C to +85°C. Key electrical specifications include a frequency tolerance of ±20ppm at normal temperature and a frequency stability of ±20ppm over the full operating temperature range. The load capacitance is specified as 7pF, and the equivalent series resistance (ESR) is 80 Ohms.

Crystals Feature Summary

• Four-pad ceramic surface-mount design provides enhanced grounding and electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance ensures simple oscillation circuit requirements without additional matching inductors.
• Industrial-grade thermal performance supports stable operation across a wide temperature range from -40°C to +85°C.

Crystals Applications

• Bluetooth and short-range wireless communication devices
• PCMCIA interface equipment
• High-density industrial control systems
• Wearable electronic devices

Crystals Procurement Notes

Verify the specific suffix 'DB16' against the official Suntsu datasheet to confirm the exact temperature grade (-40°C to +85°C) and tolerance (+/- 20ppm). Ensure the load capacitance requirement of 7pF matches the target circuit design. Request the latest manufacturing documentation to validate RoHS compliance and lead-free status for current production batches.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but EMI immunity is critical due to the four-pad structure. It is suitable for applications requiring moderate frequency precision (+/- 20ppm) over a wide industrial temperature range. Consider alternative models if tighter stability or different load capacitances are required.

Crystals Part Context

This part belongs to the SXT224 series of small-sized, industrial-grade ceramic crystals. The series is characterized by its compact 2.5mm x 2.0mm package and four-terminal configuration, designed to replace larger through-hole or two-pin SMD crystals in modern miniaturized electronics.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants with different frequencies or tolerances, such as SXT2247DB16-16.000M. Cross-brand replacements must match the 2520 package, 7pF load capacitance, and 80 Ohm ESR specifications.
