QT532G-33.3333MAAE-T

Overview

The QT532G-33.3333MAAE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 33.3333 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ω. The component provides a frequency tolerance and stability of ±30 ppm at 25°C and across the operating temperature range of -20°C to +70°C. It utilizes a surface-mount package measuring 5.0 x 3.2 x 1.2 mm.

Feature Summary

• Surface mount quartz crystal resonator
• Glass seal construction for environmental stability
• Standard 12 pF load capacitance specification

Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Procurement Notes

Verify the specific suffix 'AAE' against the manufacturer's current datasheet to confirm pin configuration and packaging details. Ensure the required frequency tolerance of ±30 ppm meets the target circuit design specifications before procurement. Confirm availability status as supply levels may vary.

Selection Notes

Select this component when a 33.3333 MHz reference is required for surface-mount designs. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the ±30 ppm stability limit for applications requiring precise timing over the specified industrial temperature range.

Part Context

This part belongs to the QT532G series of glass-sealed quartz crystals from QST. The series offers various frequencies in a compact 5.0x3.2mm SMD footprint. These components are designed for general-purpose timing applications where moderate stability is sufficient.

Replacement Considerations

Direct substitutes include other 33.3333 MHz crystals with identical 12 pF load capacitance and similar ESR values. Verify that alternative parts support the same 5.0x3.2mm package dimensions and operate within the -20°C to +70°C temperature range.
