• Extended industrial temperature operation from -40°C to +105°C
• Low ESR of 40 Ohms for efficient circuit driving
• Compact 5.0mm x 3.2mm 2-pad surface mount footprint

Crystals Applications

• Industrial control systems requiring wide temperature stability
• Automotive electronics applications
• Consumer electronics devices

Crystals Procurement Notes

Verify the specific suffix 'GAT' against the manufacturer's latest datasheet to confirm pinout and electrical specifications. Ensure the design supports the 2-pad SMD form factor. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the 10pF load capacitance with the host circuit's oscillator requirements to ensure proper frequency accuracy.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required in a compact 5.0x3.2mm package. It is appropriate for designs needing ±15ppm tolerance and operation up to 105°C. Compare against the 435F270X3IAT if a narrower temperature range (-40°C to 85°C) suffices, or other 435 series variants for different capacitance needs.

Crystals Part Context

This part belongs to the CTS 435 series of surface-mount crystals. The series offers various frequencies and packages. The 435F270X3GAT specifically targets applications demanding high reliability in harsh thermal environments due to its extended temperature rating and low ESR characteristics compared to standard commercial grade parts.

Crystals Replacement Considerations

The 435F270X3IAT is a documented alternative with similar electrical parameters but a limited temperature range of -40°C to 85°C. Verify that the reduced thermal specification meets the application requirements before substitution.
