Crystals Procurement Notes

Verify the specific suffix 'D' against official CTS documentation to confirm the exact load capacitance and ESR specifications, as variations within the 405 series may exist. Ensure the ordering code matches the required 20pF load capacitance and 12.288 MHz frequency exactly. Cross-reference the manufacturer datasheet for any recent packaging or marking changes before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required for digital systems utilizing standard microcontrollers or communication protocols. The 20pF load capacitance must match the oscillator circuit design parameters. Consider the 60 Ohm ESR limit for driver strength requirements. The wide temperature range makes it suitable for environments exceeding standard commercial limits.

Crystals Part Context

This component belongs to the CTS 405 series of surface mount crystals. The series offers various frequencies and package sizes optimized for space-constrained electronics. The 405I35D variant specifically denotes the 5.0x3.2mm footprint with industrial temperature ratings, distinguishing it from commercial grade or different size options within the broader product line.

Crystals Replacement Considerations

Direct substitutes include 405C35D12M28800 and 405I35E12M28800 from CTS-Frequency Controls. Verify that alternative part numbers maintain identical frequency, load capacitance, and ESR values to ensure circuit compatibility without redesign.
