Procurement Notes

Verify the specific suffix 'CPLB' against project requirements, as it denotes the 125°C temperature rating and 30 Ohm impedance profile, which differs from the standard 'CPLA' variant rated for 85°C. Confirm that the 15 pF internal capacitance aligns with the target oscillator circuit's external loading requirements. Ensure the 3-SMD footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this model when an extended high-temperature operating range up to 125°C is required, distinguishing it from the lower-rated CPLA series. The 30 Ohm impedance specification is critical for ensuring proper oscillation startup in the target application circuit. Verify compatibility with the specific microcontroller or logic family driving the resonator pins to guarantee signal integrity and reliable frequency locking.

Part Context
