6 FAQs about [Undervoltage capacitor]
Is a high voltage capacitor rated for 2x the working voltage a good part?
Rule of thumb round here is that caps rated for 2x the working voltage is a good (reliable) part. You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower.
Why is undervoltage a problem?
Undervoltage happens when the average voltage of equipment falls below the rated voltage amount. Frequent undervoltage can result in a degradation in equipment performance and reliability. The winding suffers a substantial amount of wear and tear in the winding and reduces the lifespan of the equipment. Why?
Why is a high voltage capacitor not a capacitor?
Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.
What is undervoltage & why is it important?
Undervoltage Undervoltage happens when the average voltage of equipment falls below the rated voltage amount. Frequent undervoltage can result in a degradation in equipment performance and reliability. The winding suffers a substantial amount of wear and tear in the winding and reduces the lifespan of the equipment.
How much voltage can a capacitor carry?
Capacitor units should be capable of continuous operation up to 110% of rated terminal rms voltage and a crest voltage not exceeding 1.2 x √2 of rated rms voltage, including harmonics but excluding transients. The capacitor should also be able to carry 135% of nominal current.
Are MLCC capacitors rated at low voltage?
You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things)
