QT216S-20.000MAHE-T

Overview

The QT216S-20.000MAHE-T is a surface-mount quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 20 MHz. It features a load capacitance of 12 pF and offers a frequency stability of ±30 ppm at 25°C and ±30 ppm across the -40°C to +85°C temperature range. The component utilizes a seam seal package with four pads, housed in a compact 2.0 mm x 1.6 mm footprint. This design supports reliable timing applications requiring precise frequency control within automotive and industrial environmental constraints.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Four-pad surface mount configuration for secure PCB attachment
• Automotive-grade reliability compliant with AEC-Q200 standards

Applications

• Automotive electronic systems requiring AEC-Q200 certification
• Industrial control circuits needing stable timing references
• Consumer electronics utilizing compact surface-mount components

Procurement Notes

Verify that the specific part number matches the required frequency tolerance and load capacitance specifications for your circuit design. Confirm that the seam seal package type aligns with your assembly process capabilities. Ensure compatibility with the intended operating temperature range of -40°C to +85°C. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 20 MHz reference signal is required with ±30 ppm stability over a wide temperature range. The 12 pF load capacitance must match the oscillator circuit design parameters. Consider the 2.0 mm x 1.6 mm size constraint for space-limited boards. Verify that the four-pad seam seal package suits the available soldering profile and mechanical stress requirements of the application environment.

Part Context

This crystal belongs to the QT216S series from QST, designed for high-reliability applications. The series emphasizes compact dimensions and robust sealing techniques. It serves as a timing element in various electronic systems where frequency accuracy is critical. The specific model integrates standard quartz resonator technology with specialized packaging to meet stringent industry standards.

Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 12 pF load capacitance and ±30 ppm stability. Compatible alternatives must share the 2.0 mm x 1.6 mm footprint and four-pad seam seal configuration. Verify that any replacement also meets AEC-Q200 qualification if used in automotive contexts. Ensure equivalent electrical parameters to maintain circuit performance without redesign.
