Most of the metallized film capacitors fail because the capacitance drops below the required tolerance. This normally occurs after the expected lifetime given by the manufacturer. The capacitance drop is generally accompanied by an increase of the loss factor.
Film Capacitors. Film capacitors are non-polarized capacitors used in a wide range of applications. They are known for their stability and reliability. Here are common problems and solutions for film capacitors: 1. Problem: Capacitor Aging - Over time, film capacitors can experience a decrease in capacitance and an increase in ESR.
The move to higher bus voltages also favors film capacitor types; the same energy is stored with smaller CV ratings at high voltage (due to the ''squared'' in E=CV2/2) so less capacity is needed, and film types are

For film capacitors, both the DC and AC rated voltage is usually in the range from several tens to several hundred volts. High-voltage types for electric power systems have an AC voltage rating on the order of several thousand volts and higher. The AC rating is the voltage for capacitors assumed to be used in circuits handling alternating current only. When used for AC, a corona

But when the capacitor is charged rapidly to a specified high voltage (under a high electric field) and then it is disconnected from the power supply, a significant voltage drop will be observed, so the capacitor energy efficiency

When voltage is applied between facing conductors, the insulator (or space) sandwiched between them will cause dielectric polarization by electrostatic induction, thus leading to the accumulation of electric charges (charging). The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function.
To verify the voltage drop, Ohm''s law and Kirchhoff''s circuit law are used, which are briefed below. Ohm''s law is represented by V → Voltage Drop (V) R → Electrical Resistance (Ω) I → Electrical Current (A). For DC closed circuits, we also use Kirchhoff''s circuit law for voltage drop calculation is as follows: Supply Voltage = Sum of the voltage drop across each

*) In case of the metallized film capacitors (evaporated metal electrode type), if voltage in excess of the withstand voltage (or apparently in excess of the withstand voltage due to the lowering of withstand voltage) is applied, self-healing will happen continuously.
The electric-field stess in metallized film capacitors may be much larger than in film foil capacitors. This is obtained thanks to the ability of the electrodes to self-heal. If a breakdown occurs in the polymer, the current will increase through the defect and on the electrode near the defect.

Metallized film capacitor; failure mode; lifetime. Electrolytic capacitors characterized by very big capacitance per volume unit, but with low rated voltages and very important power losses due to the ionic conductivity. In particular, the bigger the capacitance density, the lower the rated voltage.
For the life of a film capacitor, the Mean Time To Failure(MTTF), which is calculated by the inverse of the failure rate, is used as the basis for the life calculation. If a capacitor is used at high temperatures, its service life will be shortened due to thermal deterioration.
