Calculate High and Low Fuses in Microcontroller
Calculating high and low fuses in a microcontroller circuit is crucial for ensuring the safety and longevity of your components. This calculator helps you determine the appropriate fuse values based on the current and voltage in your circuit.
How to Use This Calculator
- Enter the current (in Amperes) and voltage (in Volts) of your circuit.
- Select the type of fuse you want to use: Slow Blow or Fast Blow.
- Click the ‘Calculate’ button.
Formula & Methodology
The formula used to calculate the fuse value is based on the power dissipation in the fuse. The power (P) can be calculated using the formula:
P = I * V
Where I is the current and V is the voltage. The fuse value (F) can then be calculated using the formula:
F = P / (I^2 * t)
Where t is the time in seconds for the fuse to blow. The time is dependent on the type of fuse:
- Slow Blow: t = 10 seconds
- Fast Blow: t = 1 second

Interactive FAQ
What is the difference between Slow Blow and Fast Blow fuses?
Slow Blow fuses take longer to blow compared to Fast Blow fuses. This is useful in circuits with inductive loads, such as motors and transformers, where the inrush current can be higher than the normal operating current.
