QT532G-40.000MAAE-T

Overview

The QT532G-40.000MAAE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 40 MHz with a frequency tolerance of ±30 ppm at 25°C. The component features a load capacitance of 12 pF and a maximum equivalent series resistance (ESR) of 50 Ohms. It is housed in a compact 2-SMD, No Lead package with dimensions of 5.0 mm x 3.2 mm x 1.2 mm. The device is designed for surface-mount applications and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Compact 2-SMD no-lead surface mount package
• Frequency stability within ±30 ppm tolerance
• Wide industrial operating temperature range

Applications

• Clock signal generation in microcontroller systems
• RF communication modules requiring 40 MHz reference
• Digital logic timing circuits

Procurement Notes

Verify the specific suffix 'AAE' against the manufacturer's current datasheet to confirm pin configuration and loading capacitance specifications. Ensure the selected variant matches the required ESR and load capacitance for the target oscillator circuit design. Cross-reference the RoHS compliance status with the latest environmental declarations provided by QST Products.

Selection Notes

Select this component when a 40 MHz frequency is required with ±30 ppm stability. The 12 pF load capacitance must match the external capacitors in the oscillator circuit. The 50 Ohm ESR limit should be compatible with the driving capability of the host oscillator IC. Verify that the 5x3.2mm footprint fits the PCB layout constraints.

Part Context

This part belongs to the QT532G series of quartz crystals from QST Products. The series offers various frequencies in a standardized 5.0x3.2mm SMD package. The model number indicates a 40 MHz frequency with AAE suffix denoting specific packaging and electrical characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 5x3.2mm SMD footprint, 12pF load capacitance, and ≤50 Ohm ESR. Verify that alternative parts meet the same ±30 ppm tolerance and -40°C to +85°C temperature range requirements.
