QT532G-54.000MAAJ-T

Overview

The QT532G-54.000MAAJ-T is a MHz quartz crystal oscillator manufactured by QST, housed in a 5.0x3.2 mm glass seal package. It operates at a nominal frequency of 54 MHz with a load capacitance of 18 pF and an equivalent series resistance of 50 Ohms. The component exhibits a frequency stability of ±30 ppm at 25°C and ±30 ppm across the -20°C to 70°C temperature range.

Feature Summary

• Utilizes a glass seal construction for enhanced environmental protection and long-term reliability.
• Provides precise timing signals with high frequency stability suitable for clock applications.

Applications

• General purpose clock generation
• Microcontroller timing circuits
• Communication equipment

Procurement Notes

Verify the specific manufacturer designation, as this part number appears in listings associated with both QST and TXC Corporation. Confirm that the glass seal package type and 18pF load capacitance match the design requirements before procurement. Ensure the operating temperature range aligns with the intended application environment.

Selection Notes

Select this component when a 54 MHz reference signal is required with tight stability constraints. The 5.0x3.2 mm footprint offers a balance between size and performance. Consider the ±30 ppm stability over the specified temperature range to ensure system timing accuracy under varying thermal conditions.

Part Context

This model belongs to the QT532G series of surface-mount quartz crystals. The series typically includes various frequencies within the MHz range, sharing common physical dimensions and packaging styles. These components are designed for standard clocking needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 54 MHz crystals in the same package with matching electrical parameters. Cross-reference models like QT532G-54.000MBBK-T or variants from other manufacturers ensuring identical load capacitance and stability ratings.
