QT325G-13.000MAAE-T

Overview

The QT325G-13.000MAAE-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, distributed by QST. It operates at a fundamental frequency of 13 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 100 Ohms. The component features a 4-pin CSMD package with glass seal construction and dimensions of 3.2 x 2.5 x 0.8 mm. Frequency tolerance and stability are both specified at ±30 ppm at 25°C and across the -20°C to +70°C operating temperature range.

Feature Summary

• Glass-sealed quartz crystal construction for enhanced environmental stability
• Surface-mount design with four-terminal configuration for reliable PCB integration
• Fundamental mode operation ensuring precise timing control

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems

Procurement Notes

Verify the manufacturer part number matches the specific suffix 'MAAE-T' to ensure correct load capacitance and tolerance specifications. Confirm that the distributor source provides official documentation from TXC Corporation or authorized channels. Check for RoHS compliance status if required by assembly standards. Ensure storage conditions align with moisture sensitivity levels defined in the datasheet to maintain performance integrity prior to soldering.

Selection Notes

Select this component when a 13 MHz fundamental frequency with ±30 ppm stability is required within a compact 3.2x2.5mm footprint. Consider the 12pF load capacitance compatibility with the target oscillator circuit's internal capacitance. Evaluate the -20°C to +70°C temperature range against the application's operational environment. Compare ESR values with driver strength capabilities to ensure reliable oscillation startup.

Part Context

This crystal belongs to the QT325G series, which utilizes a glass-seal technology to provide superior frequency stability compared to standard ceramic packages. The series is designed for applications requiring high reliability in consumer electronics and industrial control systems where space constraints necessitate small surface-mount components.

Replacement Considerations

Direct substitutes must match the 13 MHz frequency, 12pF load capacitance, 100 Ohm ESR, and 3.2x2.5mm package dimensions. Verify that alternative parts offer identical ±30 ppm tolerance and stability specifications across the same temperature range to ensure circuit compatibility.
