Film capacitors that include the F339MX251531KKM2T0 variant are generally smaller and thinner than typical electrolytic or ceramic capacitors, offering increased performance and a longer life span. As such, they are an ideal option for a range of industrial, military, and commercial applications, including avionics, healthcare, power conditioning, automotive, and lighting systems.

These capacitors are usually constructed from polypropylene, polyester, or polyphenylene sulfide film, depending on whether the capacitor is intended for a low-voltage or high-voltage application. Additionally, the dielectric substrate thickness, electrical insulation quality, dielectric losses, fire safety, and the ability to withstand extreme temperatures are all important considerations in the design of capacitors.

In general, these film capacitors have extremely low leakage current and come with either epoxy resin or non-resin impregnated encapsulations on both ends. Depending on the exact model, they range from millimeters to centimeters in size with small capacitance values typically from one picofarad to several million microfarads.

The F339MX251531KKM2T0, specifically, is a compact, axial lead, aluminum-clad polyethylene-naphthalate-film-based capacitor with an epoxy encapsulation. It has a capacitance value of 0.015uF at a voltage rating of 250VAC and offers the benefits of small size, low ESR loss, and low cost.

Well-suited for industrial, communications, and consumer electronics, the capacitor employs two molten compounds which offer excellent flame protection and mechanical protection. Its capacitance is stable over a wide range of temperatures, from 40°C to +105°C, and the maximum rated ripple current is 19mA.

In terms of working principle, the F339MX251531KKM2T0 stores electrical energy by means of two metal plates separated by a thin dielectric film. When an AC input voltage is applied, the resulting current generates an electrostatic field in the dielectric medium, resulting in a capacitance. This capacitance is expressed in terms of Farads and is determined by the thickness, area, and dielectric constant of the dielectric film.

Another important factor affecting capacitance is the construction of the electrodes. The F339MX251531KKM2T0 features high-grade aluminum foil electrodes which allow for a larger effective area and, therefore, a higher capacitance. This is achieved by forming an intricate pattern of etched aluminum panels which are insulated from each other to create a number of smaller capacitors.

Additionally, the capacitor employs a high-quality, low-coefficient polyethylene-naphthalate dielectric film, which has a very low dielectric loss factor. This means that heat generated by the capacitor is minimal, making it a highly efficient device when used in high-frequency applications.

The F339MX251531KKM2T0 is a versatile product which can be used in a variety of power conditioning and low impedence applications. Its relatively high capacitance makes it an ideal choice for filtering transients or buffering current spikes in power supplies, and its ultra-low ESR loss ensures advantageous performance in high-frequency applications.
