Film capacitors are well-known for their significant advantages over other type capacitors. A typical example is the DPM2P1K-F film capacitor from the Nichicon Corporation. This capacitor is designed for general purpose applications, including power supplies, electronic ballasts, motor drives, ultra-violet curing systems, audiovisual equipment and general industrial use.

The DPM2P1K-F film capacitor employs a thin-film, metallized polypropylene dielectric film. When viewed from its working principle, the capacitor works by charging the thin-film dielectric, which acts as an insulator between the two electrodes. This causes an electrostatic field to exist between the two electrodes. The charge on the film acts as an electrical reservoir to store energy and the resulting electrostatic field constricts or "shortens" the distance between the two electrodes.

When the two electrodes are connected together, this builds up a capacitance and therefore a current. The capacitance is determined by the plate area, plate separation, dielectric constant, and the dielectric thickness. Greater separation may or may not reduce the capacitance, depending on the effect of the dielectric medium.

The DPM2P1K-F film capacitor is designed for numerous electrical and electronic applications, including AC motor drives, inverters and uninterruptible power supplies (UPS). Its thin-film metallized polypropylene dielectric makes it a particularly attractive option for applications where electrical parameters are precisely specified and it provides superior DC stability, superior heat resistance, and superior insulation resistance. Since the capacitor is housed in a rugged, UL-rated, epoxy-filled case, it is suitable for industrial and commercial use.

Aside from power applications, the DPM2P1K-F film capacitor can also be used in many audio and video applications. For example, it can be used as a frequency and phase differentiation network in stereo speakers and sound systems. The thin-film dielectric ensures a good response, selectivity and excellent current distribution, while the epoxy-filled case ensures a predictable capacitance value.

The DPM2P1K-F capacitor is a highly versatile component, allowing for an astonishing range of applications, from power supplies to audio/video systems. With its thin-film dielectric, UL-rated epoxy-filled case, and excellent heat and insulation resistance, it provides superior DC stability. The resulting electrostatic field also offers attractive features such as quick and reliable performance, cost-effectiveness, and great flexibility in terms of operation.
