Crystals Procurement Notes

Verify the specific suffix 'W' against official documentation to confirm the hermetic ceramic SMT package variant, as standard 402 series parts may differ in construction. Confirm that the 60 Ohm ESR specification aligns with circuit requirements, distinguishing it from non-W variants which may exhibit higher resistance values such as 80 Ohms. Ensure compatibility with the intended PCB footprint for the 4-SMD no-lead configuration.

Crystals Selection Notes

Select this component when low drive chipsets and minimal power consumption are critical for the design. The 8pF load capacitance must match the oscillator circuit's external capacitors to achieve the specified 32 MHz frequency. Consider the hermetic ceramic construction if environmental sealing or enhanced reliability is required compared to standard epoxy-sealed crystals.

Crystals Part Context

This part belongs to the CTS 402W series, which is specifically engineered for IoT and portable devices. Unlike the standard 402F series, the 402W line emphasizes optimized electrical parameters for low-power operation. It serves as a specialized frequency control solution within the broader CTS crystal portfolio, targeting modern embedded systems requiring efficient energy usage.
