SXT1148AA27-27.000M

Crystals Overview

The SXT1148AA27-27.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 27 MHz with a frequency stability of ±50 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 150 Ohms. It is housed in a compact 4-SMD, No Lead package designed for automated assembly processes.

Crystals Feature Summary

• Fundamental mode operation for precise timing applications
• Surface-mount design compatible with standard reflow soldering profiles
• Stable frequency performance within specified tolerance limits

Crystals Applications

• General-purpose clock generation circuits
• Microcontroller system oscillators
• Communication module timing references

Crystals Procurement Notes

Verify the exact datasheet specifications from Suntsu Electronics to confirm thermal characteristics and moisture sensitivity levels prior to integration. Ensure that the PCB layout supports the 4-SMD no-lead package dimensions and solder mask requirements to prevent assembly defects.

Crystals Selection Notes

Select this component when a 27 MHz reference with ±50 ppm stability is required. The 8 pF load capacitance must match the oscillator circuit design. Consider the 150 Ohm ESR for drive level constraints. This part is suitable for commercial temperature ranges as indicated by related series data.

Crystals Part Context

This model belongs to the SXT1148 series of surface-mount crystals. It shares the physical footprint with other variants in the line but differs in electrical parameters such as frequency and load capacitance. The 'AA27' suffix typically denotes specific factory coding or lot information rather than functional changes.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 4-SMD no-lead packaging and matching 8 pF load capacitance. Verify that alternative parts meet the same ±50 ppm stability and 150 Ohm ESR requirements to ensure circuit compatibility.
