SXT22411AA27-20.000M

Crystals Overview

The SXT22411AA27-20.000M is a 20 MHz fundamental mode quartz crystal resonator manufactured by Suntsu Electronics, Inc. It features a frequency stability of ±50ppm and a frequency tolerance of ±50ppm. The component operates with an 11pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms maximum. Designed for surface mount applications, it utilizes a 4-SMD, no lead package configuration. The device supports base harmonic operation and is intended for use in timing circuits requiring moderate precision.

Crystals Feature Summary

• Fundamental AT-cut quartz design for stable oscillation
• 4-pin SMD package providing grounding shielding capabilities
• Optimized for low drive level operation up to 100μW

Crystals Applications

• Bluetooth wireless devices
• Short-range communication equipment
• Industrial control systems with high-density PCB layouts

Crystals Procurement Notes

Verify the specific suffix 'AA27' against official Suntsu documentation to confirm exact tolerance and temperature range specifications. Ensure the ordering quantity aligns with bulk packaging requirements rather than single-unit samples if volume production is planned. Confirm that the 4-SMD footprint matches the target PCB design guidelines precisely.

Crystals Selection Notes

Select this component when moderate frequency stability of ±50ppm is sufficient for the application. The 4-pin package is preferred over 2-pin variants to reduce electromagnetic interference in sensitive RF environments. Ensure the circuit design accommodates the 80 Ohm ESR limit and provides adequate drive level protection to maintain long-term reliability.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic SMD crystals. The series is characterized by small form factor designs suitable for space-constrained portable electronics. Unlike higher-stability variants, this model offers standard performance metrics balanced with cost-effectiveness for mass-market consumer and industrial applications.

Crystals Replacement Considerations

Direct substitutes within the same series include SXT22411AA27-26.000M for different frequency requirements. Cross-model replacements must match the 4-SMD package and 11pF load capacitance to ensure circuit compatibility without redesign.
