Overview
The QT216S-40.000METI-T is a surface-mount quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 40 MHz with a load capacitance of 10 pF and an equivalent series resistance of 50 ohms. The component provides a frequency tolerance of ±10 ppm and maintains stability within the same range across an operating temperature range of -30°C to +85°C. The physical package dimensions are 2.0 mm x 1.6 mm x 0.5 mm, utilizing a four-terminal SMD no-lead configuration suitable for automated assembly processes.
Feature Summary
- Fundamental mode quartz crystal operation
- Compact 2.0x1.6mm surface-mount footprint
- Wide industrial temperature range capability
Applications
- General-purpose timing circuits
- Microcontroller clock sources
- Communication module oscillators
Procurement Notes
Verify the specific suffix METI against official QST documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Cross-reference load capacitance requirements with the target circuit design to guarantee accurate frequency performance.
Selection Notes
Select this component when a 40 MHz reference signal is required in space-constrained designs. The 10 pF load capacitance must match the oscillator circuit's external capacitors. Verify that the 50 ohm ESR aligns with the driving circuit's power limitations to ensure stable oscillation start-up.
Part Context
This part belongs to the QT216S series of SMD crystals from QST. The series offers various frequencies and package sizes. The METI suffix indicates specific terminal plating and tape-and-reel packaging. Other variants in the family share similar mechanical footprints but differ in frequency and capacitance values.
Replacement Considerations
Direct substitutes include other 40 MHz SMD crystals with identical 2.0x1.6mm dimensions, 10 pF load capacitance, and ±10 ppm tolerance. Verify pinout compatibility and thermal characteristics before substitution.
