SXT22420BA27-20.000M

Crystals Overview

The SXT22420BA27-20.000M 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 -20°C to +70°C. Key electrical specifications include a frequency tolerance of ±30ppm, a load capacitance of 20pF, and an equivalent series resistance (ESR) of 80 Ohms.

Crystals Feature Summary

• Four-pad ceramic surface-mount design providing enhanced electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance architecture ensuring stable oscillation without the need for additional matching inductors.
• Integrated ground pads on unused terminals to minimize radiation EMI and improve signal integrity in high-density layouts.

Crystals Applications

• Bluetooth and short-range wireless communication devices
• PCMCIA interface equipment
• Industrial control systems requiring high-density board layouts

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact frequency stability and temperature range ratings. Ensure that the selected variant matches the required load capacitance and ESR limits for the target oscillator circuit design to guarantee reliable startup performance.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility demands exceed standard two-lead capabilities. The four-terminal configuration allows direct connection to the main ground plane, reducing the need for external shielding components while maintaining precise timing accuracy for wireless protocols.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade ceramic crystals from Suntsu Electronics. The series is engineered for applications requiring robust performance in compact form factors. The specific part number indicates a 20 MHz frequency with defined tolerance and packaging characteristics suitable for modern electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must match the 2.5x2.0mm 4-SMD package, 20 MHz frequency, 20pF load capacitance, and 80 Ohm ESR. Verify that alternative sources support the same -20°C to +70°C operating temperature range and offer comparable frequency stability ratings.
