Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as this component specifies 10pF. Confirm that the target application environment remains within the -40°C to 85°C operational temperature range. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions of 2.00mm x 1.60mm. Check for RoHS3 compliance if required by your manufacturing standards.

Crystals Selection Notes

Select this part when a 26 MHz fundamental frequency is required with high stability. The 10pF load capacitance must match the oscillator circuit's requirements to ensure accurate frequency generation. Consider the 100 Ohm ESR value for drive level sensitivity. The compact SMD form factor is ideal for space-constrained designs requiring reliable timing performance in industrial environments.

Crystals Part Context

This component belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for surface mount technology. The 402F26012IAR specifically provides a standard 26 MHz output commonly used in digital logic and communication interfaces.
