Unlock the full potential of your 555 timer projects with our intuitive 555 Timer Calculator. Whether you're designing an astable multivibrator for continuous oscillations or a monostable multivibrator for single-pulse generation, this tool provides precise component values for resistors and capacitors. Optimize your circuit design for desired frequency, pulse width, and duty cycle with ease.
Formula:
Astable Mode:
- Frequency (f) = 1.44 / ((R1 + 2 * R2) * C1)
- High Time (tH) = 0.693 * (R1 + R2) * C1
- Low Time (tL) = 0.693 * R2 * C1
- Duty Cycle (%) = ((tH / (tH + tL)) * 100)
Monostable Mode:
- Pulse Width (tP) = 1.1 * R * C
Where:
- R1, R2, R = Resistance in Ohms (Ω)
- C1, C = Capacitance in Farads (F)
