Calculadora de Capacitor de Desacoplamento — Formula
## Decoupling Capacitor Sizing
### Formula
**C = I x dt / dV**
Where I is the transient current, dt is the duration of the transient, and dV is the maximum allowed voltage droop. Place decoupling caps as close to the IC power pins as possible.
### Formula
**C = I x dt / dV**
Where I is the transient current, dt is the duration of the transient, and dV is the maximum allowed voltage droop. Place decoupling caps as close to the IC power pins as possible.
Exemplo Resolvido
0.5 A transient for 10 us, maximum 100 mV droop.
- dt = 10 / 1000000 = 0.00001 s
- dV = 100 / 1000 = 0.1 V
- C = 0.5 x 0.00001 / 0.1 = 0.00005 F = 50 uF
