Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm the 20pF load capacitance matches the target circuit design requirements. Ensure the 4-SMD footprint aligns with the board layout specifications. Cross-reference the manufacturer datasheet for detailed soldering profiles and moisture sensitivity levels prior to procurement.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required for industrial environments. The 20pF load capacitance distinguishes it from 13pF or 18pF alternatives in the same series. Consider the 60 Ohm ESR value for oscillator drive level calculations. The 4-SMD package offers a balance between size and thermal performance suitable for dense electronic assemblies.

Crystals Part Context

This part belongs to the CTS 405 Series of surface-mount crystals. It shares the standard 5.00mm x 3.20mm footprint with other frequencies in the series but differs in electrical parameters such as load capacitance and ESR based on the specific model code. The 'I' designation typically denotes the industrial temperature grade within the product family.

Crystals Replacement Considerations

Direct substitutes include 405C35E14M31818 and 405I35D14M31818 from CTS-Frequency Controls. Verify that alternative parts match the 20pF load capacitance and 60 Ohm ESR to ensure circuit compatibility without redesign.
