Crystals Procurement Notes

Verify the specific suffix 'IAT' against manufacturer documentation to confirm terminal configuration and packaging details. Cross-reference the load capacitance specification, as distributor listings may vary between 9pF, 10pF, and 12pF for similar part numbers. Ensure compatibility with the target circuit's drive level requirements, typically 10 µW for this series. Confirm RoHS3 compliance status prior to integration.

Crystals Selection Notes

Select this component when a 54 MHz reference signal is required with ±20 ppm accuracy. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for impedance matching. The surface mount package requires appropriate reflow soldering profiles. Evaluate thermal performance within the specified -40°C to +85°C range for the intended application environment.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers sub-miniature surface mount crystals. The series covers frequencies from 16 MHz to 96 MHz. These components are designed for high Q factor performance and are commonly used in IoT, IIoT, and M2M applications requiring reliable timing references in compact form factors.
