Crystals Procurement Notes

Verify the specific suffix IKR against the manufacturer's official datasheet to confirm pin configuration and loading parameters. Ensure the design environment supports the specified ESR and load capacitance requirements. Confirm RoHS compliance status if required by project specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±10ppm tolerance is required. The 120 Ohm ESR value must be compatible with the oscillator circuit's drive level constraints. Consider the 4-SMD package size for PCB layout compatibility and thermal performance within the -40°C to +85°C operational range.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package options for general-purpose timing applications. The 402F16012IKR specifically addresses needs for precise 16 MHz timing in consumer and industrial electronics requiring small form factors.

Crystals Replacement Considerations

Direct substitutes include parts with identical electrical parameters and package dimensions. Verify that any replacement maintains the 16 MHz frequency, 9pF load capacitance, and 120 Ohm ESR to ensure circuit compatibility.
