QTM325-30.000MBA-T

Overview

The QTM325-30.000MBA-T is a standard clock oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 30.000 MHz with CMOS output levels. The device features a frequency stability of ±50 ppm over the operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 1.10mm. The component is RoHS compliant and lead-free, suitable for timing circuits requiring precise clock signals in consumer and industrial electronics.

Feature Summary

• CMOS output signal generation for digital logic interfacing
• Compact 3.2x2.5 mm surface-mount footprint
• Wide operating temperature range from -40°C to +85°C
• Frequency stability of ±50 ppm across temperature range

Applications

• Standard clock timing for microprocessors and microcontrollers
• Data communication interface synchronization

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm voltage levels and pin configuration. Ensure the required frequency tolerance of ±50 ppm meets the target circuit specifications. Confirm RoHS compliance status if restricted substances are prohibited in the final assembly. Check for any specific handling requirements related to the 4-SMD package during reflow soldering processes.

Selection Notes

Select this component when a compact, low-power CMOS oscillator is required for 30 MHz applications. Consider the ±50 ppm stability requirement against the system's jitter tolerance. Evaluate the 3.2x2.5 mm package size constraints against available PCB real estate. Compare the -40°C to +85°C operating range with the environmental conditions of the intended deployment scenario.

Part Context

This part belongs to the QTM325 series of quartz crystal oscillators produced by QST. The series offers various frequency options within a standardized small outline package. It serves as a direct replacement for other 30 MHz CMOS oscillators in similar form factors. The product line is designed to provide reliable timing solutions for mass-produced electronic devices requiring consistent clock performance.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with existing footprints and electrical parameters before substituting with other manufacturers' 30 MHz CMOS oscillators. Ensure that any alternative component matches the 4-SMD package dimensions and voltage output levels.
