• Optimized for low-power applications with a 100 uW excitation level specification
• Engineered for compact PCB layouts using a small 5.0 x 3.2 mm SMD footprint

Crystals Applications

• Microcontroller clock sources
• Digital signal processing circuits
• Communication interface timing

Crystals Procurement Notes

Verify the specific suffix 'K' against official CTS documentation to confirm the 8 pF load capacitance and -20°C to +70°C temperature range. Ensure circuit design accounts for the 40 Ohm ESR limit. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement.

Crystals Selection Notes

Select this component when an 8 pF load capacitance is required for the oscillator circuit. It is suitable for commercial grade environments (-20°C to +70°C). Compare against the 405I series if industrial temperature ratings are needed, or the 405C/D series if higher load capacitances like 18 pF or 20 pF are necessary for the system design.

Crystals Part Context

This part belongs to the CTS 405 series of general-purpose surface-mount crystals. The series offers various load capacitance options and temperature grades. The 405C35K variant specifically targets standard commercial applications requiring precise 16 MHz frequencies in space-constrained designs.

Crystals Replacement Considerations

Direct substitutes within the same family include 405C35D16M00000 (18 pF load) and 405C35E16M00000 (20 pF load), provided the circuit can accommodate different load capacitances. Cross-manufacturer replacements require matching frequency, load capacitance, and physical dimensions.
