• Timing references in communication modules requiring 19.2 MHz standard
• Embedded systems and consumer electronics utilizing SMD components

Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm the ESR specification of 60 Ohms matches the circuit design requirements. Ensure the 13pF load capacitance aligns with the oscillator circuit's total stray capacitance. Check RoHS compliance status for environmental regulations.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required within an industrial temperature environment. The 60 Ohm ESR must be compatible with the driving circuit's oscillation conditions. The 4-SMD package size suits high-density PCB layouts. Compare against commercial grade parts if the -40°C lower limit is unnecessary for the application.

Crystals Part Context

This part belongs to the CTS 405 Series of general-purpose quartz crystals. The series offers various frequencies and packages optimized for cost-effective timing solutions. The 405I variant specifically targets applications demanding reliability across broader thermal variations than standard commercial parts allow.

Crystals Replacement Considerations

Direct substitutes include other manufacturers offering 19.2 MHz crystals with identical 13pF load capacitance and 60 Ohm ESR. Verify that any replacement maintains the same 4-SMD(5x3.2) footprint and industrial temperature rating to ensure mechanical and thermal compatibility.
