555 Timer Monostable Calculator 555 Timer Monostable Calculator 555 Timer Monostable Calculator Resistor R (Ω) Capacitor C (F) Calculate The 555 timer in monostable mode produces a single output pulse of a specific duration when triggered. This calculator computes the output pulse width (time high) for given resistor and capacitor values in a monostable 555 timer circuit. Example Calculation Given values: R = 10kΩ, C = 100µF. Pulse Width (Time High) = 1.1 * R * C Pulse Width = 1.1 * 10000 * 0.0001 = 1.1 seconds Subscribe to Updates Get the latest creative news from SmartMag about art & design.
