QT216S-40.000METC-T

Overview

The QT216S-40.000METC-T is a fundamental-mode quartz crystal resonator manufactured by QST Products, LLC. It operates at a nominal frequency of 40 MHz and utilizes a 2.0 x 1.6 mm surface-mount package with a height of 0.50 mm. The component features seam-seal construction in a ceramic housing with four pads. It provides a frequency stability of ±10 ppm across the industrial temperature range of -30°C to +85°C and requires a load capacitance of 9 pF.

Feature Summary

• Seam-seal ceramic construction for environmental protection
• Fundamental-mode operation ensuring stable oscillation
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• High-power motor control cabinets
• General-purpose microcontroller clock sources

Procurement Notes

Verify the specific suffix against official documentation to confirm exact specifications. Datasheets may vary between distributors; ensure the document matches the manufacturer's current revision. Confirm availability status directly with authorized suppliers as stock levels fluctuate. Cross-reference the load capacitance requirement with your circuit design before procurement.

Selection Notes

Select this component when a compact, low-profile crystal is required for 40 MHz applications. The ±10 ppm stability meets standard industrial requirements. Ensure the PCB layout accommodates the 2.0 x 1.6 mm dimensions and 9 pF load capacitance. Verify that the operating temperature range aligns with the intended environment.

Part Context

This part belongs to the QT216S series of fundamental-mode quartz crystals from QST Products. The series offers various frequencies and packages, with the 2.0 x 1.6 mm size providing a balance between performance and board space efficiency. It is designed for general timing applications requiring reliable frequency generation.

Replacement Considerations

Compatible substitutes include the QT216S-40.000METQ-T and QT216S-40.000METV-T from QST, which share similar electrical characteristics and form factors. Other manufacturers offering 40 MHz crystals in 2.0 x 1.6 mm packages with ±10 ppm stability may also be considered if pin compatibility is verified.
