QT252S-16.000MAAV-T

Overview

The QT252S-16.000MAAV-T is a surface-mount quartz crystal oscillator manufactured by QST. It operates at a fundamental frequency of 16 MHz with a load capacitance of 8 pF and an equivalent series resistance of 100 Ohms. The component features a 4-SMD, no-lead package with dimensions of 2.5 mm x 2.0 mm x 0.55 mm. Frequency stability is rated at ±30 ppm at 25°C and ±30 ppm over the operating temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction for environmental protection
• Surface mount design for automated assembly
• High frequency stability within specified temperature ranges

Applications

• Digital timing circuits
• RF communication modules
• Microcontroller clock sources

Procurement Notes

Verify the specific suffix AAV against the manufacturer datasheet to confirm load capacitance and stability ratings. Ensure the ordering part number matches the required frequency tolerance and temperature range specifications before procurement.

Selection Notes

Select this component when a 16 MHz reference signal is required in space-constrained designs. The 8 pF load capacitance must align with the host circuit's input requirements to ensure accurate oscillation frequency.

Part Context

This model belongs to the QT252S family of seam-seal crystals. Variants within this series differ primarily in operating frequency, load capacitance values, and stability tolerances while maintaining consistent physical footprint and mounting characteristics.

Replacement Considerations

Compatible substitutes include other 16 MHz crystals with identical 2.5x2.0mm SMD footprints and 8pF load capacitance. Verify that alternative parts meet the same ±30ppm stability requirements across the -20°C to +70°C range.
