Crystals Procurement Notes

Verify the specific load capacitance requirement of 20 pF against the target circuit design to ensure proper oscillation. Confirm that the PCB layout accommodates the 3.2mm x 2.5mm SMD package dimensions. Ensure the selected variant meets the required ±30 ppm frequency stability for the application. Check compliance with RoHS directives if environmental regulations apply. Validate the series resistance of 40 Ohms matches the oscillator driver strength capabilities.

Crystals Selection Notes

Select this component when a 25 MHz reference is required with moderate frequency stability. The 20 pF load capacitance must match the external capacitors in the oscillator circuit. Consider the 40 Ohm series resistance for drive level sensitivity. The wide temperature range suits general industrial environments. Compare against other C3E series variants if different frequencies or package sizes are needed.
