Crystals Procurement Notes

Verify the complete part number including suffixes against official CTS documentation to ensure correct load capacitance and tolerance specifications. Confirm that the intended application environment falls within the specified -40°C to +85°C operating range. Check for any specific marking requirements or packaging preferences required by your manufacturing process before placing orders.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency crystal is required with tight tolerance specifications. Ensure the circuit design accounts for the 20 pF load capacitance to maintain accurate frequency performance. Consider the physical footprint constraints of the 5.00 mm x 3.20 mm package during PCB layout planning.

Crystals Part Context

This part belongs to the CTS 405 Series of surface-mount crystals, designed for general-purpose frequency control in consumer and industrial electronics. The series provides various frequencies and packages to support diverse design needs while maintaining consistent quality and reliability standards across the product line.

Crystals Replacement Considerations

Direct substitutes include 405C35E27M00000 and 403I35E27M00000 from CTS-Frequency Controls. Cross-manufacturer replacements must match the 27 MHz frequency, 20 pF load capacitance, and 4-SMD package dimensions.
