SXT2248FA16-20.000M

Crystals Overview

The SXT2248FA16-20.000M is a surface-mount ceramic crystal manufactured by Suntsu Electronics, Inc., designed for frequency control applications. It operates at a fundamental frequency of 20.000 MHz with a standard tolerance of ±10 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, no-lead package configuration, measuring 2.5 mm x 2.0 mm. This industrial-grade device supports stable oscillation in compact electronic designs requiring precise timing signals.

Crystals Feature Summary

• Four-pad surface mount design provides enhanced grounding and electromagnetic interference shielding compared to two-pin alternatives.

Crystals Applications

• Bluetooth low energy devices
• Short-range wireless communication equipment
• Industrial control systems

Crystals Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm temperature range and stability specifications. Ensure the 4-SMD footprint matches the target PCB layout. Confirm that the 80 Ohm ESR aligns with the oscillator circuit requirements for reliable startup at operating temperatures.

Crystals Selection Notes

Select this component when space constraints require a 2.5mm x 2.0mm footprint but superior EMI performance is necessary. The four-terminal structure offers better noise immunity than standard two-lead crystals. Verify that the 20 MHz frequency and 8 pF load capacitance match the host microcontroller or RF transceiver specifications.

Crystals Part Context

This part belongs to the SXT224 series of small-size ceramic SMD crystals from Suntsu Electronics. The series is characterized by its 4-pad construction, which improves reliability and signal integrity in high-density layouts. It serves as a frequency reference for various digital and radio frequency circuits.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz, 8 pF, 4-SMD ceramic crystals with similar ESR ratings. Cross-reference pinout compatibility and thermal characteristics before substitution.
