QT216S-27.120MAAV-T

Overview

The QT216S-27.120MAAV-T is a surface-mount quartz crystal resonator manufactured by QST Corporation. It operates at a nominal frequency of 27.12 MHz with a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 90 Ohms and requires a load capacitance of 8 pF for proper operation. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm. This device is designed for use in timing applications requiring stable frequency generation within embedded systems.

Feature Summary

• Surface-mount quartz crystal resonator design
• Compact 4-SMD no-lead package configuration
• Stable frequency output capability

Applications

• Timing source for embedded designs
• Motor control DSP controller circuits
• General purpose clock generation

Procurement Notes

Verify the specific manufacturer datasheet for complete electrical characteristics and mechanical drawings before integration. Confirm that the 27.12 MHz frequency and 90 Ohm ESR match the target circuit requirements. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications to guarantee reliable soldering and long-term performance in the final assembly.

Selection Notes

Select this component when a small form factor is required for 27.12 MHz applications. The ±30 ppm tolerance suits standard timing needs where high precision is not critical. Consider the 8 pF load capacitance requirement to ensure oscillator circuit stability. The low ESR value supports efficient energy transfer in driving circuits.

Part Context

This part belongs to the QT216S series of quartz crystals from QST Corporation. The series offers various frequencies in a standardized 2.0 x 1.6 mm package. These components are commonly used in consumer electronics and industrial equipment where space constraints limit the use of larger through-hole or standard SMD crystals.

Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, 4-SMD no-lead package, and similar electrical parameters. Verify compatibility with existing oscillator circuits before swapping manufacturers.
