QTM216J-12.000MBJ-T

Overview

The QTM216J-12.000MBJ-T is a surface-mount crystal oscillator manufactured by QST, designed for compact electronic applications. It operates at a nominal frequency of 12 MHz with a stability of ±50 ppm. The device utilizes CMOS output and functions on a 3.3V supply voltage, drawing a maximum current of 22 mA. It features an enable/disable control pin and supports an operating temperature range from -40°C to 105°C. The component is housed in a 4-SMD, no-lead package measuring 2.0mm x 1.6mm.

Feature Summary

• CMOS output interface with low electromagnetic interference characteristics
• Integrated enable and disable functionality for power management
• Wide industrial operating temperature range for environmental resilience

Applications

• Embedded systems requiring precise clock synchronization
• Industrial communication modules
• Consumer electronics with space constraints

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when placing orders. Confirm that the 3.3V logic level matches the target circuit's I/O requirements. Ensure the ±50 ppm frequency stability meets the system timing tolerance. Check for RoHS compliance status if required by project specifications. Validate the 4-SMD footprint dimensions against the PCB layout.

Selection Notes

Select this model when a small form factor is critical for the design. Consider the 22 mA current consumption for battery life calculations. The CMOS output is suitable for digital logic interfaces. Evaluate the ±50 ppm stability against the application's jitter sensitivity. Compare the -40°C to 105°C range with the expected environmental conditions.

Part Context

This oscillator belongs to the QTM216 series, which focuses on miniaturized solutions for modern electronics. The series offers various frequencies and packages to suit different design needs. QST manufactures these components to provide reliable timing sources for high-density circuits. The 2.0x1.6mm size allows for placement in tight spaces where larger oscillators cannot fit.

Replacement Considerations

Check datasheets for direct pin-compatible alternatives with similar electrical parameters. Verify that substitute parts maintain the same 3.3V supply and CMOS output levels. Ensure the replacement offers comparable frequency stability and temperature range.
