QT325G-27.000MAGE-T

Overview

The QT325G-27.000MAGE-T is a passive quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 27 MHz with a standard load capacitance of 18 pF. The component exhibits a frequency tolerance and stability of ±30 ppm within the commercial temperature range of -20°C to +70°C. It utilizes an SMD3225-4P package, measuring 3.2 mm x 2.5 mm x 0.8 mm. The equivalent series resistance (ESR) is typically specified at 60 Ohms for this configuration. The device complies with RoHS standards and is intended for precise timing applications in consumer electronics and communication devices requiring stable clock signals.

Feature Summary

• Provides stable 27 MHz oscillation with ±30 ppm frequency accuracy
• Compact SMD3225-4P footprint suitable for automated assembly
• Operates reliably across commercial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronic device oscillators

Procurement Notes

Verify the complete part number against official QST documentation to ensure correct suffix alignment. Confirm that the 'A' suffix corresponds to the specific ±30 ppm tolerance and -20°C to +70°C temperature range required for your design. Cross-reference the load capacitance specification with your circuit design requirements to guarantee oscillator stability. Ensure compliance with RoHS directives if applicable to your manufacturing process.

Selection Notes

Select this component when a 27 MHz reference signal is required for commercial-grade applications. The ±30 ppm stability suits general timing needs rather than high-precision navigation or telecommunications. Consider the 18 pF load capacitance requirement for oscillator circuit design. Evaluate the SMD3225-4P package dimensions against available PCB real estate. Compare ESR specifications with oscillator driver strength capabilities to prevent startup failures.
