Crystals Procurement Notes

Verify the specific suffix 'X-R' against the manufacturer's current datasheet to confirm exact packaging and tape-and-reel specifications. Ensure that the required load capacitance matches the circuit design requirements, as variations exist within the C3E series. Confirm compliance with relevant environmental directives such as RoHS before final integration into the production workflow.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 8 MHz applications with moderate stability needs. The 18 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 500 ohm ESR limit to ensure proper start-up conditions within the target application environment.
