Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended temperature range (-40°C to +85°C), distinguishing it from commercial variants. Confirm the load capacitance requirement matches the circuit design, as this unit specifies 20pF. Ensure the 4-SMD package dimensions align with the PCB land pattern. Cross-reference the manufacturer datasheet for the latest environmental compliance status and recommended soldering profiles.

Crystals Selection Notes

Select this component when an industrial-grade temperature range is required alongside standard 30 MHz timing. The 20pF load capacitance must match the oscillator circuit's input capacitance. Consider the 50 Ohm ESR limit for driving capability requirements. This part belongs to the 405 series, ensuring compatibility with other components in the same family regarding mechanical and electrical interface standards.

Crystals Part Context

This crystal belongs to the CTS 405 series of surface-mount fundamental crystals. The 'I' designation typically denotes the extended temperature variant within this product line. It shares the same physical package dimensions as other 405 series parts but differs in material composition or processing to withstand wider thermal stress compared to commercial grade equivalents.

Crystals Replacement Considerations

Direct substitute: 405C35S30M00000. Verify that the commercial grade temperature range (-20°C to +70°C) meets the application requirements before substitution. Other similar alternatives may exist but require careful verification of load capacitance and ESR specifications.
