QT532S-16.000MAAJ-T

Overview

The QT532S-16.000MAAJ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 16 MHz. It features a frequency stability of ±30 ppm at 25°C and ±30 ppm over the industrial temperature range of -20°C to +70°C. The component utilizes an 18 pF load capacitance and exhibits a maximum series resistance of 40 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0 x 3.2 x 0.9 mm, designed for surface-mount assembly.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Compact 4-SMD no-lead footprint for automated placement
• Industrial temperature range operation capability

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics oscillators

Procurement Notes

Verify the specific suffix MAHJ or MAAJ against the manufacturer's current datasheet to confirm exact tolerance and packaging specifications. Ensure the required load capacitance matches the target circuit design before procurement. Confirm RoHS compliance status through official documentation.

Selection Notes

Select this component when a 16 MHz reference with ±30 ppm stability is required for space-constrained designs. The 18 pF load capacitance must align with the oscillator circuit requirements. Consider the 40 Ohm ESR limit for driver strength compatibility within the application system.

Part Context

This part belongs to the QT532S series of seam-seal crystals from QST. The series offers various frequencies and stability grades. The 16.000 variant provides a standard clocking solution for digital systems requiring precise timing synchronization in portable devices.

Replacement Considerations

QT532S-16.000MEEQ-T offers higher stability (±10 ppm) but may differ in cost and availability. Direct substitutes from other manufacturers require verification of pinout, dimensions, and electrical parameters.
