The component features a load capacitance of 10pF and an equivalent series resistance (ESR) of 40 Ohms. It utilizes a 2-SMD, No Lead package with dimensions of 5.0mm x 3.2mm. The device supports fundamental mode operation and functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Surface mount configuration in a compact 5.0mm x 3.2mm footprint
• Fundamental mode operation for precise timing control
• Compliance with RoHS3 standards for environmental safety

Crystals Applications

• Precision timing circuits requiring stable 27 MHz reference
• Consumer electronics utilizing surface mount assembly
• Industrial equipment operating within standard commercial temperature ranges

Crystals Procurement Notes

Verify the specific package type against design requirements, as datasheet references indicate a 2-SMD form factor distinct from other series variants. Confirm that the 40 Ohm ESR aligns with oscillator circuit capabilities. Ensure the ±10ppm tolerance meets system accuracy specifications before integration into final assemblies.

Crystals Selection Notes

Select this component when a larger 5.0mm x 3.2mm surface mount footprint is acceptable for improved mechanical robustness compared to smaller packages. Choose based on the requirement for 40 Ohm ESR and 10pF load capacitance. Consider the commercial temperature range limits for environmental suitability in the target application.

Crystals Part Context

This part belongs to the CTS 435 series of MHz crystals. It differs from the 416 series by offering a larger physical package size while maintaining similar electrical parameters like 27 MHz frequency and 10pF load capacitance. The 435 series provides alternative mounting options for designs prioritizing package dimensions over minimal footprint constraints.
