QT252S-30.000MAAV-T

Overview

The QT252S-30.000MAAV-T is a surface-mount quartz crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 30 MHz with a load capacitance of 8 pF. The component exhibits a frequency stability of ±30 ppm at 25°C and across the -40°C to +85°C temperature range. It features a 4-SMD, no-lead package with dimensions of 2.5 x 2.0 x 0.55 mm and an equivalent series resistance of 60 Ohms.

Feature Summary

• Seam seal construction for reliable performance
• Surface mount design for automated assembly
• Tight frequency tolerance for precision timing

Applications

• Microcontroller clock sources
• Communication module timing
• Digital signal processing circuits

Procurement Notes

Verify the manufacturer designation carefully, as the model number appears in listings for both TXC Corporation and QST Products, LLC. Confirm the specific datasheet version and electrical parameters match your circuit requirements before ordering. Ensure the package dimensions and soldering profile are compatible with your manufacturing process.

Selection Notes

Select this component when a 30 MHz reference is required in a compact 2.5x2.0 mm footprint. The 8 pF load capacitance must align with the host oscillator circuit's input capacitance. Consider the ±30 ppm stability requirement against the system's total allowable frequency error budget.

Part Context

This part belongs to the QT252S series of seam-seal quartz crystals. Similar variants include the QT252S-24.000MDDQ-T and QT252S-48.000MAHE-T, which offer different frequencies and stability specifications within the same physical package family.

Replacement Considerations

Direct substitutes may include other 30 MHz SMD crystals with identical 2.5x2.0 mm dimensions and 8 pF load capacitance. Verify that alternative parts meet the ±30 ppm stability requirement and have compatible ESR values.
