• Compact surface-mount design suitable for automated assembly
• Wide industrial temperature range capability

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix 'D' against the official datasheet to confirm the exact load capacitance and ESR specifications, as variations exist within the 403 series. Ensure the ordering documentation explicitly references the 18pF load requirement to match circuit design parameters. Confirm RoHS compliance status through the manufacturer's current environmental declarations prior to final procurement approval.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a small form factor. The 18pF load capacitance must align with the host circuit's external capacitor values. Consider the 100 Ohm ESR for drive level sensitivity. The 4-SMD package requires appropriate footprint design for reflow soldering processes.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. It shares the physical footprint with other frequencies in the series but differs in electrical characteristics such as load capacitance and ESR. The 'I' suffix typically indicates industrial temperature range, while 'D' denotes specific electrical tolerances defined by the manufacturer.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 403I35E30M00000 and 406I35E11M05920 from CTS-Frequency Controls. Verify that alternative parts match the 12 MHz frequency requirement and compatible load capacitance before substitution.
