Procurement Notes

Verify the manufacturer designation as QST when sourcing this specific part number. Confirm that the load capacitance requirement matches the system design of 8 pF. Ensure the operating temperature range of -20°C to +70°C aligns with the intended application environment. Check datasheet specifications for aging rates and equivalent series resistance values prior to integration.

Selection Notes

Select this component when a 32 MHz fundamental mode crystal is required in a leadless SMD form factor. The ±30 ppm tolerance suits applications where moderate frequency accuracy is sufficient. Consider the 8 pF load capacitance compatibility with the oscillator circuit's input capacitance. Evaluate thermal requirements against the specified -20°C to +70°C operational window.
