Monostable Multivibrator Pulse Duration Calculator

This page offers a handy calculator for determining the pulse duration (also known as pulse width) of a monostable multivibrator circuit. The calculator is based on the popular 555 timer IC configuration.

It requires you to input the resistance (R) and capacitance (C) values used in your circuit. In return, it provides you with the calculated pulse width, pulse period, or pulse duration (Tp).

EXAMPLE:

• Inputs: Resistance (R1) = 220 kΩ, Capacitance (C1) = 1 µF
• Outputs: Pulse Duration (or Pulse Width) = 0.242 seconds or 242 ms
