Crystals Procurement Notes

Verify the specific suffix 'ITR' against official CTS documentation to confirm tape-and-reel packaging specifications. Ensure the 4 pF load capacitance matches the target oscillator circuit requirements. Confirm RoHS3 compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with tight ±10 ppm tolerance is required. The 4 pF load capacitance dictates compatibility with specific microcontroller or RF oscillator circuits. Consider the 50 Ohm ESR for impedance matching and the 10 uW drive level to prevent over-driving the crystal element during selection.
