QT532G-14.31818MAAE-T

Overview

The QT532G-14.31818MAAE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 14.31818 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a ±30 ppm frequency tolerance at 25°C and maintains stability within ±30 ppm across the commercial temperature range of -20°C to +70°C. Housed in a compact 2-SMD, no-lead package measuring 5.0 x 3.2 mm, it provides reliable timing solutions for embedded systems requiring precise clock signals.

Feature Summary

• Surface-mount design for automated assembly
• Stable frequency performance across commercial temperature ranges
• Compact footprint suitable for space-constrained PCB layouts

Applications

• Embedded system clock generation
• Microcontroller timing sources
• Communication interface synchronization

Procurement Notes

Verify the complete part number including suffixes to ensure correct tolerance and temperature rating. Confirm package dimensions match board space requirements. Check RoHS compliance status if environmental regulations apply. Validate supplier authenticity through authorized channels to prevent counterfeit components. Review datasheet specifications for soldering profile recommendations.

Selection Notes

Choose this component when a 14.31818 MHz reference is required with moderate stability. Ensure the operating environment stays within -20°C to +70°C for specified accuracy. Compare ESR values against oscillator circuit requirements. Consider package size constraints during layout planning. Verify load capacitance compatibility with the target oscillator configuration.

Part Context

This crystal belongs to QST's standard SMD crystal lineup, offering a balance of performance and cost-effectiveness. The 5x3.2mm form factor is widely adopted in consumer electronics and industrial control modules. It serves as a foundational timing element for digital circuits requiring stable clock references without high-precision military specifications.

Replacement Considerations

Cross-reference parts with identical 14.31818 MHz frequency, 12pF load capacitance, and 50 Ohm ESR. Verify matching 5.0x3.2mm package dimensions and pinout compatibility. Ensure substitute components meet or exceed the ±30 ppm tolerance requirement across the same temperature range.
