QT325G-26.000MEIE-T

Overview

The QST QT325G-26.000MEIE-T is a surface-mount crystal oscillator operating at a fundamental frequency of 26 MHz. It utilizes a 3.2 x 2.5 mm package with a height of 0.8 mm, designed for compact electronic assemblies. The component features a load capacitance of 12 pF and exhibits a frequency stability of ±10 ppm over the temperature range of -20°C to +70°C. This quartz crystal resonator provides reliable timing signals for digital circuits requiring precise clock synchronization.

Feature Summary

• Compact 3.2x2.5mm surface-mount footprint suitable for space-constrained designs
• High frequency stability of ±10 ppm across industrial temperature ranges
• Lead-free construction compliant with RoHS standards

Applications

• Mobile communication devices
• Consumer electronics timing circuits
• Industrial control systems

Procurement Notes

Verify the specific suffix 'E' against official QST documentation to confirm the exact load capacitance and temperature stability parameters. Ensure compatibility with reflow soldering profiles specified in the manufacturer datasheet. Confirm that the 12pF load capacitance matches the circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 26 MHz reference signal is required with tight tolerance specifications. The ±10 ppm stability ensures accurate timing in applications sensitive to frequency drift. Consider the 12pF load capacitance requirement for proper oscillator circuit tuning. The small form factor makes it ideal for modern portable devices where board space is limited.

Part Context

This part belongs to the QT325G series from QST, which offers various frequency options and stability grades within a standardized 3.2x2.5mm SMD package. The series supports different load capacitances and temperature ranges, allowing designers to choose components based on specific environmental and performance needs for timing applications.

Replacement Considerations

Direct substitutes include other QT325G variants with matching 26 MHz frequency and ±10 ppm stability, such as QT325G-26.000MEEQ-T or QT325G-26.000MAEIE-T, provided they share identical load capacitance and package dimensions.
