Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for any specific handling instructions regarding ESD sensitivity during assembly.

Selection Notes

Select this component when a low-profile, low-power oscillator is required for 1.8V logic systems. Consider the 13.55 MHz frequency specifically for applications needing this exact clock rate. Evaluate the need for power-down functionality if battery life is a critical constraint. Compare package size against available board real estate to ensure fitment within the 2.0x1.6mm envelope.
