WebMay 1, 2024 · Derating of PP and PET type capacitors is more pronounced at a 1.25% per °C derating factor beyond the 85°C rated temperature. T MAX is where the graph stops (125°C for PET and 150°C for PEN). Yes, you can safely operate a capacitor above it’s rated temperature, but at a reduced voltage, and not beyond its maximum temperature … WebFeb 27, 2024 · This is independent of the voltage derating. You state that your voltage derating is -63% (only 37 uF remaining from 100 uF originally), so if your temperature derating is -20% at your worst case (usually highest, but check the curves), then at that temperature and voltage, you would actually only have (100uF x 0.37 x 0.80) = 29.6 uF.

WebMay 18, 2024 · As a baseline, KEMET provides data that can be used with the MIL-HDBK-217 formula to calculate Failures In Time (FIT) for ceramic and tantalum capacitors. Measuring the number of failures over time provides a failure rate (λ). The failure rate that occurs during one billion device hours is called the Failure In Time (FIT). WebConventional electrolytic capacitors tend to fail prematurely when their liquid electrolyte dries up‚ which happens in response to elevated temperatures and long on times. Conventional tantalum capacitors are one possible solution to these premature failures. However, tantalums require voltage derating to avoid a very undesirable failure mode—
