When selecting resistors, a 1/4 watt rating is typically sufficient for low voltage projects, as higher wattages require significantly higher voltages to reach their limits. The discussion highlights that 800nF is not a standard capacitor value, with suggestions to use a combination of 470nF and 330nF capacitors instead. It is noted that 820nF is a more common value, which may suffice unless exact specifications are critical. The conversation also touches on the importance of understanding the circuit's requirements, particularly regarding component tolerances and the necessity for accurate values. Overall, participants emphasize the need for clarity in circuit design to ensure appropriate component selection.
