Crystals Procurement Notes

Verify the specific suffix 'E' against design requirements, as it denotes the 20pF load capacitance variant. Confirm that the 50 Ohm ESR aligns with the oscillator circuit design. Ensure the -20°C to +70°C temperature range meets operational needs. Cross-reference the 4-SMD 5x3.2mm footprint with PCB layout constraints. Validate RoHS3 compliance if required by project specifications.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required in a small 5x3.2mm SMD package. Choose this part over wider packages if space constraints are critical. Consider the 20pF load capacitance requirement for circuit compatibility. Verify that the ±30ppm initial tolerance satisfies system accuracy requirements. Ensure the industrial temperature range covers the intended operating environment.

Crystals Part Context

This component belongs to the CTS 405 Series, which offers reduced size ceramic packaged crystals. The series is engineered for applications demanding high-density mounting. The 405C35E27M00000 represents a specific frequency and tolerance configuration within this family, utilizing the standard 4-SMD leadless form factor common to the series.

Crystals Replacement Considerations

Public confirmed substitutes include 405C35D27M00000, which differs only in load capacitance (18pF vs 20pF). ECS-270-20-30B-TR is listed as a similar alternative from ECS Inc. Verify pinout and electrical parameters before substitution.
