QT216G-27.000MEDQ-T

Overview

The QT216G-27.000MEDQ-T is a quartz crystal component manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 27 MHz and utilizes a load capacitance of 10 pF. The device features a compact 4-SMD, No Lead package with body dimensions measuring 2.0 x 1.6 x 0.6 mm. Frequency stability is specified at ±10 ppm at 25°C and ±20 ppm across the temperature range of -20°C to +70°C.

Feature Summary

• Surface-mount design with no lead construction for automated assembly
• Compact 2.0 x 1.6 mm footprint suitable for space-constrained layouts
• High frequency stability with ±10 ppm tolerance at room temperature

Applications

• Clock signal generation in digital communication systems
• Frequency reference sources for microcontroller circuits
• Timing components in portable electronic devices

Procurement Notes

Verify the specific suffix MEDQ-T against official QST documentation to confirm the exact temperature range and stability specifications. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision.

Selection Notes

Select this component when a 27 MHz reference is required in a minimal SMD footprint. The 10 pF load capacitance must match the oscillator circuit design. Consider the ±10 ppm initial accuracy for precision timing needs. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare physical dimensions against PCB silkscreen constraints.

Part Context

This part belongs to the QST QT216G series of miniature quartz crystals. The series offers various frequencies and stability grades within a standardized 2.0 x 1.6 mm package. The MEDQ-T suffix typically denotes specific stability and temperature characteristics unique to this variant within the broader product line.

Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 10 pF load capacitance, and 2.0 x 1.6 mm package size. Verify equivalent stability ratings of ±10 ppm at 25°C. Check for compatible mounting pads and electrical parameters. Consult manufacturer cross-reference lists for validated alternatives.
