555 Timer Calculator
This 555 Timer calculator helps you determine the output pulse duration or time delay in monostable mode based on resistor (R) and capacitor (C) values. It’s useful for electronics students, hobbyists, and engineers working with timing circuits.

555 Timer Delay Formula
Where:
- T = Time delay in seconds
- R = Resistance in ohms (Ω)
- C = Capacitance in farads (F)
This formula applies to the monostable mode of a 555 timer IC, where the output goes high for a specific period defined by R and C.
The 555 Timer IC is widely used in electronics for timing applications such as delays, pulse generation, and oscillation. In monostable mode, it produces a single output pulse when triggered. This calculator simplifies the design process by instantly computing the time delay based on standard RC components. For example, using a 100kΩ resistor and a 10µF capacitor results in a delay of 1.1 seconds. It’s perfect for building timers, LED blinkers, and basic logic circuits.
