QT216S-39.000MAAV-T

Overview

The QT216S-39.000MAAV-T is a surface-mount crystal oscillator manufactured by QST Corporation, operating at a nominal frequency of 39 MHz. This component utilizes a 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. It features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 50 Ohms. The device offers a frequency tolerance of ±30 ppm and is designed for applications requiring stable clock signals in compact electronic systems.

Feature Summary

• Compact 2.0x1.6 mm surface-mount footprint suitable for space-constrained designs
• Seam-sealed construction for environmental stability
• Clipped sine wave output format for digital interfacing

Applications

• Clock generation for microcontrollers and processors
• Timing reference for communication interfaces
• Consumer electronics requiring precise frequency control

Procurement Notes

Verify the manufacturer designation carefully, as the part number appears in listings under both QST and TXC Corporation due to historical brand transitions or distributor cataloging practices. Confirm the specific datasheet version matches the required frequency tolerance and package type before procurement. Ensure compatibility with reflow soldering profiles specified in the official documentation.

Selection Notes

Select this component when a 39 MHz clock source is required in a minimal footprint. The 8 pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm tolerance against system timing requirements. Verify the 50 Ohm ESR aligns with the driving circuit's specifications for reliable oscillation startup.

Part Context

This part belongs to the QT216S series of surface-mount crystals. It shares the same physical dimensions and general characteristics with other frequencies in the series, such as the QT216S-36.000MAAV-T and QT216S-50.000MAAV-T. The series is characterized by its small size and seam-sealed construction.

Replacement Considerations

Direct substitutes include other 39 MHz crystals in the 2.0x1.6 mm SMD package with matching 8 pF load capacitance and similar ESR values. Cross-reference with TXC Corporation equivalents if sourcing from different distributors, ensuring electrical parameters remain identical.
