Resonators Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct package style and tolerance specifications. Confirm that the intended operating temperature range aligns with the component's rated specifications. Check for any specific handling requirements during soldering processes as indicated in the manufacturer's datasheet to maintain electrical integrity.

Resonators Selection Notes

Choose this component when space constraints require a low-profile solution compared to traditional crystal oscillators. Consider the inherent frequency drift characteristics relative to the application's timing accuracy requirements. Evaluate the parasitic effects of the PCB layout on the resonant frequency, as ceramic resonators are sensitive to stray capacitance variations in the surrounding circuit environment.

Resonators Part Context

This model belongs to Murata's CSTLS series of ceramic resonators, which are widely used in consumer electronics and industrial control systems. The series offers a balance between cost-effectiveness and performance, serving as an alternative to quartz crystals where extreme precision is not mandatory. These components are commonly found in appliances, remote controls, and simple computing devices requiring basic timing functions.

Resonators Replacement Considerations

Direct substitutes must match the 7.2 MHz frequency, 18 pF load capacitance, and 4-SMD package dimensions. Verify equivalent frequency tolerance and temperature coefficient specifications. Ensure the replacement component maintains compatibility with the existing oscillator circuit topology and drive level requirements.
