Monostable multivibrator pulse duration calculator

This page covers monostable multivibrator pulse duration (i.e. width) calculator. It is 555 IC based calculator which takes R and C as inputs and provides pulse width or pulse period or pulse duration (Tp) as output.

Resistance in KOhm (input1) :

Capacitance in µfarads (input2) :

Pulse Duration in sec(output) :

Inputs: Resistance (R1) = 220K-Ohm, Capacitance (C1) = 1 µF
Outputs: Pulse Duration (or Pulse Width) = 0.242 second or 242 ms
