QT532G-10.000MAHJ-T

Overview

The QT532G-10.000MAHJ-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 10 MHz with a load capacitance of 18 pF and an equivalent series resistance of 80 Ohms. The component exhibits a frequency stability of ±30 ppm at 25°C and ±30 ppm across the industrial temperature range of -40°C to +85°C. It utilizes a glass-sealed package with dimensions of 5.0 x 3.2 x 1.2 mm, featuring two SMD terminals.

Feature Summary

• Glass-sealed quartz construction for enhanced environmental durability
• Surface-mount design compatible with automated assembly processes
• Industrial temperature range operation ensuring stable performance in varying conditions

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics oscillators

Procurement Notes

Verify the specific suffix 'MAHJ-T' against official QST documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with PCB footprint requirements for the 5.0x3.2mm SMD package. Cross-reference datasheets for reflow soldering profiles and storage conditions to maintain component integrity during procurement and handling.

Selection Notes

Select this component when a 10 MHz reference with ±30 ppm stability is required for industrial environments. Consider the 18 pF load capacitance requirement for circuit design matching. Evaluate the 80 Ohm ESR against oscillator circuit capabilities. Compare against alternative packages if space constraints differ from the 5.0x3.2mm form factor.

Part Context

This part belongs to the QT532G series of quartz crystals, characterized by small surface-mount footprints and glass-seal technology. The series offers various frequency options within the MHz range, catering to general-purpose timing applications where moderate stability and compact size are prioritized over high-precision or wide-temperature automotive grades.

Replacement Considerations

Direct substitutes include other 10 MHz, 18 pF, ±30 ppm crystals in 5.0x3.2mm SMD packages from manufacturers such as TXC or Abracon. Verify pinout compatibility and mechanical height limits. Ensure equivalent ESR and drive level specifications to prevent frequency shifts or oscillator failure in existing designs.
