QT216S-27.000MEEQ-T

Overview

The QT216S-27.000MEEQ-T is a 27 MHz quartz crystal resonator manufactured by QST. It features a nominal frequency of 27 MHz with a frequency tolerance and stability of ±10 ppm at 25°C and across the -20°C to +70°C operating temperature range. The component has a load capacitance of 10 pF and an equivalent series resistance (ESR) of 90 Ohms. It utilizes a 4-SMD, no lead package with body dimensions of 2.0 x 1.6 x 0.5 mm.

Feature Summary

• Compact 2.0x1.6mm surface-mount design for space-constrained applications
• High frequency stability of ±10 ppm across industrial temperature range
• Low equivalent series resistance for efficient circuit operation

Applications

• Clock generation for microcontrollers and digital processors
• Timing reference for communication interfaces
• Frequency control in consumer electronic devices

Procurement Notes

Verify the specific suffix MEEQ against official QST documentation to confirm exact tolerance and temperature specifications. Ensure compatibility with PCB footprint requirements for the 4-SMD no-lead package. Cross-reference datasheet parameters such as ESR and load capacitance with target circuit design constraints before finalizing procurement.

Selection Notes

Select this component when a 27 MHz timing source with ±10 ppm stability is required within a compact 2.0x1.6mm footprint. Consider the 10 pF load capacitance requirement for oscillator circuit design. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare ESR values with other available options to ensure optimal drive level performance.

Part Context

This part belongs to the QT216S series of quartz crystals from QST. The series offers various frequencies and packages suitable for general-purpose timing applications. The 27 MHz variant provides a standard clock frequency for many embedded systems. The SMD form factor supports automated assembly processes common in modern electronics manufacturing.

Replacement Considerations

Direct substitutes include the QT216S-27.000MAAJ-T and QT216S-27.000MAAV-T from QST, which share similar physical dimensions but may differ in tolerance or stability specifications. Verify electrical parameters carefully when swapping between these variants.
