Crystals Procurement Notes

Verify the specific suffix ILR against the manufacturer's current datasheet to confirm package orientation and lead finish specifications. Ensure compatibility with the target circuit's load capacitance requirements before integration. Confirm RoHS3 compliance status through official documentation.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required in a small 2.00mm x 1.60mm footprint. The 100 Ohm ESR and 12 pF load capacitance must match the oscillator circuit design. Consider the -40°C to +85°C operating range for industrial or commercial environments.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and packages optimized for space-constrained electronics. The 402F20022ILR specifically provides a standard 20 MHz output in a widely used SMD form factor.

Crystals Replacement Considerations

Direct substitutes include 402F20022ILT and 402F20022IJR from CTS-Frequency Controls. Parameter-equivalent options may include variants with different load capacitances if the circuit allows adjustment.
