Procurement Notes

Verify the specific load capacitance requirements against your oscillator circuit design before procurement. Ensure that the soldering profile adheres to QST's recommended thermal guidelines to maintain frequency accuracy. Confirm that the packaging format matches your pick-and-place equipment specifications. Always request the latest datasheet from authorized distributors to confirm current manufacturing status and any potential obsolescence notices prior to finalizing purchase orders.

Selection Notes

Select this component based on its 25 MHz operating frequency and 3215 package dimensions. Consider the required load capacitance and equivalent series resistance values for your specific oscillator topology. Evaluate the temperature stability requirements of your application to ensure the standard commercial grade meets operational needs. Verify compatibility with your PCB layout constraints regarding footprint size and spacing requirements.

Part Context

This part belongs to QST's line of surface-mount quartz crystal resonators. It is engineered for use in devices requiring precise timing signals. The model designation indicates a 25 MHz frequency and a specific package variant.
