Crystals Procurement Notes

Verify the specific suffix AC3 against official Epson documentation to confirm the exact stability and packaging specifications. Ensure that the required load capacitance matches the circuit design parameters. Confirm compliance requirements such as RoHS3 status with the supplier. Check for any recent product change notifications or obsolescence notices from the manufacturer before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal with ±18 ppm total stability is required. The 9 pF load capacitance must align with the oscillator circuit design. Consider the 60 Ohm ESR limit for driver level compatibility. The 3.2mm x 2.5mm footprint dictates PCB layout constraints. Verify thermal performance requirements against the -40°C to +85°C operational range.
