SXT2148DC17-26.000M

Crystals Overview

The SXT2148DC17-26.000M is a 26 MHz fundamental AT-cut crystal oscillator manufactured by Suntsu Electronics, Inc. It features a 4-SMD, no-lead ceramic package with dimensions of 2.0 x 1.6 mm. The component offers a frequency tolerance of ±20 ppm and a load capacitance of 8 pF. Equivalent series resistance (ESR) is specified at a maximum of 100 Ohms for the 26–40.999 MHz range. Operating temperature stability is rated at ±10 ppm within the -20°C to +70°C commercial grade environment.

Crystals Feature Summary

• Fundamental AT-cut resonance design ensures reliable oscillation without requiring overtone circuits.
• Compact 2.0 x 1.6 mm four-pad surface-mount ceramic package optimizes board space utilization.
• Low equivalent series resistance supports stable startup conditions across defined temperature ranges.

Crystals Applications

• Bluetooth audio devices requiring precise clock synchronization
• Portable communication modules with strict spatial constraints
• High-speed peripheral interfaces demanding low jitter timing sources

Crystals Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact tolerance and temperature grades. Ensure compatibility with PCB footprint specifications for 4-SMD no-lead packages. Confirm drive level requirements do not exceed typical limits to maintain long-term frequency stability and prevent over-driving damage during operation.

Crystals Selection Notes

Select this component when space-constrained designs require a 26 MHz reference with ±20 ppm initial accuracy. Consider the -20°C to +70°C operating range for commercial applications. Evaluate ESR limits against oscillator circuit capabilities to ensure adequate start-up margins under worst-case conditions.

Crystals Part Context

This part belongs to the SXT214 series of miniature ceramic crystals. The series provides various frequency options from 16 MHz to 60 MHz in a standardized 2.0 x 1.6 mm footprint. Different suffixes denote variations in tolerance, stability, and temperature range, allowing designers to balance performance and cost for embedded systems.

Crystals Replacement Considerations

Cross-reference with other 2.0x1.6mm 26MHz crystals having 8pF load capacitance and similar ESR limits. Verify pinout compatibility for 4-SMD no-lead configurations before substitution.
