QT532G-8.000MBBE-T

Overview

The QT532G-8.000MBBE-T is a fundamental parallel quartz crystal manufactured by QST, operating at a nominal frequency of 8 MHz. It features a surface-mount package with dimensions of 5.0 x 3.2 mm and a height of 1.2 mm. The component utilizes a glass-seal construction for enhanced stability. Key electrical parameters include a load capacitance of 20 pF and an equivalent series resistance (ESR) of 80 Ohms. Frequency tolerance is specified as ±50 ppm across the operating temperature range of -40°C to +85°C.

Feature Summary

• Fundamental parallel resonance quartz crystal design
• Glass-seal construction for environmental stability
• Compact 2-SMD no-lead surface mount form factor

Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Procurement Notes

Verify the specific suffix 'BBE' against official QST documentation to confirm exact tolerance and temperature range specifications, as suffixes define critical performance variations. Ensure compatibility with PCB footprint dimensions of 5.0 x 3.2 mm during integration. Cross-reference datasheets for soldering profile requirements to maintain glass-seal integrity.

Selection Notes

Select this component when a stable 8 MHz reference is required in space-constrained designs. The 20 pF load capacitance must match the oscillator circuit design. Verify that the ±50 ppm stability meets system timing requirements over the full industrial temperature range of -40°C to +85°C.

Part Context

This part belongs to the QT532G series of quartz crystals from QST. The series offers various frequency options and tolerance grades defined by alphanumeric suffixes. The 5.0 x 3.2 mm package size provides a balance between performance and board space efficiency compared to larger through-hole alternatives.

Replacement Considerations

Direct substitutes may include other 8 MHz crystals in 5.0x3.2mm packages with matching 20pF load capacitance and similar ESR. Verify pinout compatibility and thermal characteristics before substitution.
