Don’t Let Your Components Fry: A Practical Guide to Derating Calculation derating calculation

P_max = 1.0 × 0.538 = 0.538 Watts

Open your current design. Calculate the actual power/voltage stress at your max operating temperature. If any component is running above 80% of its datasheet max, upgrade it now. Most datasheets provide a

Components have theoretical maximum ratings printed on their datasheets. However, running a resistor at 100% of its rated power at 80°C ambient is a recipe for disaster. This is where comes in. derating calculation

Derating Factor = (70) / (130) = 0.538
