Film capacitors are a type of capacitors that use a polyester or polypropylene film as the dielectric layer instead of ceramic or air. The F339X142248KII2B0 is a polyester film capacitor with capacitance of 0.00148 μF (148nF), voltage rating up to 250V (a class X2 capacitor), tolerance of ±10% (K), temperature range of -55°C to +85°C (II) and radial tapped leads (B0). Polyester (PET) film capacitors are the most common dielectric configuration used for film capacitors, offering high stability, a good temperature range, good capacitance tolerance, and reasonable cost.

The working principle of film capacitors is based on the same principles of other electrical capacitors. They consist of two conductive electrodes made of a thin dielectric film placed in between. The electrodes are connected to each other using metal or other conductive material, forming a capacitor. An applied electric field forms an electric field in the dielectric material, which then causes an attraction between the charges on the electrodes. This creates an electric field, thus allowing the capacitor to store energy and carry a charge.

The most common application of the F339X142248KII2B0 is in power supplies, such as switching power supplies and variable speed motor drives, and they are also ideal for use in high-voltage circuits, due to their temperature range and long life expectancy. Due to their low impedance and low inductance, they can also be used in audio signal circuits, for coupling and as noise suppression.

In addition, film capacitors are also used in filter circuits, energy storage applications, in pulse-forming networks, and in communication networks. As they provide a very low Equivalent Series Resistance (ERS), they are also used in high-frequency circuits as well as in microwave circuits, as the low impedance and capacitance found in the F339X142248KII2B0 can help to reduce losses in the signal.

The F339X142248KII2B0 offers a wide range of advantages, including low dissipation factor, high stability, reduced power losses, good temperature range, high capacitance tolerance, and reasonable cost. This makes them an ideal choice for many applications that require high performance and long life. In addition, the small size of the F339X142248KII2B0 makes it easy to install in a range of different configurations.
