QT216S-25.000MAAV-T

Overview

The QT216S-25.000MAAV-T is a 25 MHz quartz crystal manufactured by QST, housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. It operates in fundamental mode and features a load capacitance of 8pF and an equivalent series resistance of 90 Ohms. The component provides a frequency stability of ±30ppm at 25°C and maintains this tolerance across an operating temperature range of -20°C to 70°C.

Feature Summary

• Fundamental mode quartz crystal operation
• Compact 4-SMD no-lead surface mount package
• Seam seal construction for environmental protection

Applications

• Clock signal generation for microcontrollers
• Frequency reference for communication modules
• Timing circuits in consumer electronics

Procurement Notes

Verify the specific manufacturer datasheet for the QT216S-25.000MAAV-T to confirm RoHS compliance and lead-free status. Ensure that the required load capacitance matches the circuit design specifications. Cross-reference the part number with official QST documentation to validate the frequency tolerance and temperature range requirements for the intended application environment.

Selection Notes

Select this component when a small form factor is critical for PCB layout constraints. The 2.0x1.6 mm package size allows for high-density mounting. Consider the ±30ppm stability requirement against system timing needs. The fundamental mode operation ensures efficient power usage compared to overtone modes.

Part Context

This part belongs to the QST line of surface-mount quartz crystals. It is designed for applications requiring precise timing in space-constrained devices. The seam seal technology enhances reliability against moisture and contaminants compared to standard epoxy-sealed alternatives.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 8pF load capacitance, and 4-SMD 2.0x1.6mm footprint. Verify equivalent ESR and stability ratings from alternative manufacturers before integration.
