QTM216J-30.000MBJ-T

Overview

The QTM216J-30.000MBJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a nominal frequency of 30 MHz. It utilizes a crystal resonator and features a standard XO output type with low electromagnetic interference characteristics. The device supports an enable/disable function and operates on a 3.3V supply voltage. It is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm. Frequency stability is specified at ±50ppm, with aging of ±1.5ppm per year. The operational temperature range extends from -40°C to +105°C, and the maximum supply current is 10mA.

Procurement Notes

Verify the specific suffix 'MBJ' against official QST documentation to confirm voltage, temperature, and load capacitance specifications. Ensure the ordering part number matches the required frequency tolerance and package variant. Cross-reference manufacturer datasheets for environmental compliance and reliability data prior to procurement.

Selection Notes

Select this component when a 30 MHz CMOS clock source with enable/disable control is required in a 2.0x1.6mm footprint. Consider the ±50ppm stability and -40°C to +105°C range for industrial applications. Verify supply voltage compatibility with the 3.3V requirement and ensure PCB layout supports the 4-SMD no-lead package dimensions.

Part Context

This oscillator belongs to the QTM216 series, which offers various frequencies and packages within the 2.0x1.6mm form factor. The J suffix typically denotes specific electrical or environmental parameters defined by QST. This model provides a standardized solution for space-constrained designs requiring precise timing signals with power control capabilities.

Replacement Considerations

Direct substitutes include other 30MHz 3.3V CMOS oscillators in 4-SMD 2.0x1.6mm packages with similar stability ratings. Verify pinout compatibility and enable/disable logic levels before substitution. Alternative models from other manufacturers must match the electrical specifications and thermal performance requirements.
