QT216S-19.200MAAV-T

Overview

The QT216S-19.200MAAV-T is a surface-mount crystal oscillator manufactured by QST, designed for precise timing applications. It operates at a nominal frequency of 19.2 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 90 Ohms. The component features a tight frequency tolerance of ±30 ppm at 25°C and maintains stability across a temperature range of -20°C to +70°C. Housed in a compact 4-SMD, no-lead package measuring 2.0 x 1.6 mm, it supports lead-free assembly processes compliant with RoHS standards.

Feature Summary

• Compact 2.0 x 1.6 mm surface-mount footprint suitable for space-constrained designs
• High frequency stability with ±30 ppm tolerance over specified operating temperatures
• Lead-free construction compliant with environmental regulations

Applications

• Embedded communication systems requiring stable clock signals
• Microcontroller-based embedded devices
• Consumer electronics with limited board space

Procurement Notes

Verify the specific suffix 'MAAV-T' against official QST documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SMD reflow profiles. Confirm that the 8 pF load capacitance matches the target circuit design requirements before procurement.

Selection Notes

Select this component when a 19.2 MHz reference signal is required within a 2.0 x 1.6 mm envelope. Consider the 90 Ohm ESR and 8 pF load capacitance for proper oscillator circuit tuning. Evaluate the ±30 ppm tolerance against system jitter requirements and verify operation within the -20°C to +70°C industrial temperature range.

Part Context

This part belongs to the QST QT216S series of surface-mount crystals. The series offers various frequencies and package sizes optimized for modern PCB layouts. The 19.2 MHz variant is commonly used in digital signal processing and communication interfaces where precise timing is critical.

Replacement Considerations

Direct substitutes must match the 19.2 MHz frequency, 8 pF load capacitance, 90 Ohm ESR, and 2.0 x 1.6 mm package dimensions. Verify pinout compatibility and electrical characteristics with alternative manufacturers before integration.
