QT216G-27.000MEEQ-T

Overview

The QT216G-27.000MEEQ-T is a quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 27 MHz. It features a clipped sine wave output format and is housed in a compact surface-mount package with dimensions of 2.0 mm x 1.6 mm x 0.5 mm. The device supports a load capacitance of 10 pF and exhibits a frequency stability of ±10 ppm. Designed for precision timing applications, it operates within a temperature range of -30°C to +85°C and requires a supply voltage of 3.3 V.

Feature Summary

• Compact 2.0x1.6mm surface-mount footprint for space-constrained designs
• High frequency stability of ±10 ppm for precise timing requirements
• Clipped sine wave output suitable for digital clock circuits
• Operates on a standard 3.3V supply voltage

Applications

• Precision timing circuits in embedded systems
• Clock generation for microcontrollers and processors
• Communication modules requiring stable frequency references
• Consumer electronics with strict size limitations

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and tolerance match the design requirements. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Check the operating temperature range against environmental conditions. Ensure compatibility with the required load capacitance of 10 pF for accurate frequency performance.

Selection Notes

Select this component when a small form factor is critical alongside high frequency accuracy. The 27 MHz frequency is suitable for various communication standards. Consider the clipped sine wave output if interfacing directly with digital logic inputs. Evaluate the ±10 ppm stability against stricter requirements that might necessitate an oscillator instead of a crystal.

Part Context

This part belongs to the QT216G series of quartz crystals from QST, designed for general-purpose timing applications. It complements other variants in the lineup offering different frequencies and stability levels. The series is known for its reliability in consumer and industrial electronics where size and performance are balanced priorities.

Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 2.0x1.6mm packages and ±10 ppm stability. Verify pinout compatibility and load capacitance specifications before substitution. Alternative manufacturers may offer similar components but require validation of electrical parameters and thermal characteristics.
