QT325G-12.000MAHQ-T

Overview

The QT325G-12.000MAHQ-T is a surface-mount quartz crystal resonator manufactured by QST. It operates at a nominal frequency of 12 MHz with a load capacitance of 12 pF and an equivalent series resistance of 60 Ohms. The component features a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 0.90mm. Frequency stability and tolerance are rated at ±30ppm across the operating temperature range of -40°C to +85°C.

Feature Summary

Seam-sealed SMD construction for environmental protection
Wide operating temperature range from -40°C to +85°C
Standard 12pF load capacitance compatibility

Applications

General purpose clock generation in consumer electronics
Microcontroller system timing references
Communication module oscillator circuits

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct frequency stability and temperature range specifications. Confirm package type and pin configuration match design requirements before procurement. Request current datasheets from authorized distributors to validate availability and lead times.

Selection Notes

Select this component when a 12 MHz reference with ±30ppm stability is required for industrial or commercial environments. Ensure the application circuit supports the specified 12pF load capacitance. Compare alternative packages if board space constraints differ from the 3.2x2.5mm footprint.

Part Context

This part belongs to the QT325G series of quartz crystals designed for surface mount applications. The series offers various frequency options and stability grades suitable for cost-sensitive electronic designs requiring reliable timing signals.

Replacement Considerations

Direct substitutes include other QT325G variants with identical electrical parameters but different frequency values. Cross-reference with other manufacturers' 3.2x2.5mm SMD crystals offering ±30ppm stability at 12MHz for supply chain flexibility.
