QT325S-30.400MAAE-T

Overview

The QT325S-30.400MAAE-T is a surface-mount crystal resonator manufactured by QST Products, LLC. It operates at a nominal frequency of 30.4 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a standard SMD package measuring 3.2 mm x 2.5 mm. Frequency stability is rated at ±30 ppm across the operating temperature range of -20°C to +70°C.

Feature Summary

Provides stable oscillation for clock generation circuits
Designed for compact surface-mount assembly processes
Maintains frequency tolerance within specified industrial temperature limits

Applications

Microcontroller clock sources
Communication interface timing
Industrial control system oscillators

Procurement Notes

Verify the specific suffix codes against official QST documentation to confirm exact electrical parameters such as load capacitance and temperature range. Ensure the ordering part number matches the required frequency stability and package dimensions before procurement. Cross-reference distributor listings with manufacturer datasheets to validate authenticity and technical specifications.

Selection Notes

Select this component when a 30.4 MHz signal is required for embedded systems. Consider the 12 pF load capacitance requirement for circuit design compatibility. Evaluate the ±30 ppm stability against system timing accuracy needs. Confirm that the 3.2x2.5 mm footprint fits the available PCB space constraints.

Part Context

This model belongs to the QT325S series of thin-film or bulk acoustic wave crystals from QST. These components are engineered for high reliability in consumer and industrial electronics. The series offers various frequency options and stability grades to suit different application requirements.

Replacement Considerations

Direct substitutes include other QT325S variants with matching 30.4 MHz frequency and 12 pF load capacitance. Verify pin compatibility and thermal characteristics when considering alternative manufacturers. Ensure replacement parts meet the same ±30 ppm stability specification.
