QT216S-44.000MEEQ-T

Overview

The QT216S-44.000MEEQ-T is a quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 44 MHz. It features a load capacitance of 10 pF and offers a frequency tolerance and stability of ±10 ppm at both 25°C and the extended temperature range of -20°C to +70°C. The component utilizes a 4-SMD, no-lead package with dimensions of 2.0 mm x 1.6 mm and a height of 0.7 mm. It employs seam seal technology for environmental protection.

Feature Summary

• Seam sealed construction for enhanced environmental durability
• Compact 2.0x1.6 mm surface-mount footprint
• Stable frequency performance across industrial temperature ranges

Applications

• Precision timing circuits requiring stable clock signals
• Industrial electronic systems operating in variable temperatures
• Communication equipment utilizing 44 MHz reference frequencies

Procurement Notes

Verify that the specific order matches the QT216S-44.000MEEQ-T designation to ensure correct frequency and package type. Confirm compatibility with the target circuit's load capacitance requirements of 10 pF. Check datasheet specifications for soldering profiles suitable for the 4-SMD no-lead package. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component when a 44 MHz signal source is required within a constrained board area. The ±10 ppm stability supports applications needing consistent timing accuracy under thermal variation. Consider the 10 pF load capacitance requirement for proper oscillator circuit design. Evaluate the seam-sealed package benefits against standard open-can alternatives for long-term reliability needs.

Part Context

This part belongs to the QT216S series of quartz crystals from QST. The series includes variants with different frequencies such as 25 MHz and 32 MHz. All members share the same 2.0x1.6 mm SMD form factor and seam-seal construction. The series targets compact electronics requiring reliable frequency generation.

Replacement Considerations

Direct substitutes include other 44 MHz crystals with identical 2.0x1.6 mm dimensions and 10 pF load capacitance. Verify equivalent ±10 ppm stability ratings for seamless integration. Cross-reference impedance characteristics if driving circuit sensitivity is high.
