8.2: Capacitors and Capacitance
Each dielectric material has an associated loss factor or loss tangent. The loss tangent is numerically equal to the dissipation factor (DF) and is a measure of loss in the capacitor''s dielectric at RF frequencies. The effect of this loss will cause the dielectric to heat.
5 Ways to Test a Capacitor
The capacitance value of 50uF is exactly the same and the 450VAC rated capacitor has a better tolerance. 330VAC implies its a "Starting" capacitor, 450VAC implies its a "Run" capacitor. As the nominal voltage of 450V is higher than 330V, you can use a 450V rated capacitor inplace of a 330V rated one, although the physical size may be different.

This paper presents the reliability testing of film capacitors used within a pulsed electro-mechanical transducer system. Operation is characterised by fast energy transfer from the storage element to a load, leading to typical peak current levels in excess of 10 kA, with pulse widths of a few tens of μs and a nominal repetition frequency of 0.05 Hz.
How to Test a Capacitor with a Digital Multimeter: The ...
While a constant voltage is applied across a capacitor, you can expect the charge to be steady and the current to be zero. To perform a DC test the voltage must be raised to some level, and then after a time lowered (increasing and decreasing charge) causing ...
The current probe was calibrated so featured with a flat response, and a wide bandwidth ranges from DC to 25 MHz. Hence, the cutoff problem at low frequency does not occur. Because the current probe has a large measurement range of 25 A rms, in order to obtain a more accurate result in the experiment, the current wire was wound ten turns …
