Crystals Procurement Notes

Verify the specific suffix 'IKT' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the load capacitance requirement of 8pF matches the target circuit design. Confirm compliance with RoHS3 standards if required by project specifications. Check for any obsolescence notices or lifecycle changes directly from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental crystal is required with tight ±20ppm stability. The 60 Ohm ESR must align with the oscillator circuit's drive level constraints. The 8pF load capacitance dictates the necessary external capacitor values for proper frequency tuning. Consider the 4-SMD footprint and 0.55mm height limits for PCB layout compatibility.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for surface mount technology. The 402 series generally provides fundamental mode operation suitable for general-purpose timing applications. Specific electrical characteristics vary by model within the series based on frequency and package type.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 8pF load capacitance, 60 Ohm ESR, and 4-SMD 2.00x1.60mm package. Verify that alternative components support the same -40°C to 85°C operating range and ±20ppm stability. Cross-reference pinout and mounting dimensions to ensure mechanical compatibility.
