QT325S-30.000MEEQ-T

Overview

The QT325S-30.000MEEQ-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 30 MHz with a load capacitance of 10 pF. The component features a seam seal package measuring 3.2 x 2.5 mm and utilizes a four-pad ceramic construction. Frequency tolerance and stability are specified at ±10 ppm at 25°C and ±10 ppm across the operating temperature range of -20°C to +70°C. The equivalent series resistance (ESR) is rated at 50 ohms.

Feature Summary

Seam seal construction utilizing a four-pad ceramic design for reliable surface-mount integration.
Stable operation suitable for embedded communication applications requiring precise timing.
Compact physical dimensions facilitating efficient placement on printed circuit boards.

Applications

Embedded communication systems
Microcontroller clock sources
Digital signal processing circuits

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with QST in distributor catalogs but may appear under TXC Corporation branding in other contexts. Confirm the operating temperature range and load capacitance match the target circuit design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 30 MHz reference with ±10 ppm stability is required within a -20°C to +70°C environment. Ensure the application circuit provides a 10 pF load capacitance to maintain frequency accuracy. Consider the 4-pad seam seal package for mechanical robustness in high-vibration scenarios compared to standard two-pin packages.

Part Context

This model belongs to the QT325S series of surface-mount quartz crystals. The series offers various frequency options and stability grades, distinguished by suffix codes indicating temperature ranges and tolerance levels. This specific variant targets mid-range stability needs for consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include the QT325S-30.000MBBK-T for ±50 ppm stability or the QT325S-12.000MDIE-T for different frequencies. Verify that any replacement maintains the 10 pF load capacitance and 3.2x2.5 mm footprint to ensure board compatibility.
