Film capacitors, which are also known as foil capacitors, are electrical components used in a wide range of applications, including AC/DC coupling, power conditioning, signal processing and energy storage. B32671P4224J289 is a type of film capacitor manufactured by Wima, which features high quality and long-life.

In general, film capacitors consist of two layers of dielectric material, between which a thin metal layer is sandwiched. This metal layer acts as the plate of the capacitor, and its presence between the two dielectrics significantly increases the capacitance. B32671P4224J289 is a metallised polypropylene film capacitor with non-inductive construction, which provides superior performance in high frequency applications. It also offers a wide temperature range, from -40°C up to +85°C.

The product with B32671P4224J289 is designed for bypass, AC/DC coupling, and charge/discharge applications, and can be used in switch mode power supply, audio amplifiers and other similar applications. Regarding its working principle, film capacitors depend on the electrostatic fields created between two conductive plates. An electrical charge is stored between the two metal layers within the capacitor, thereby creating a charge difference between the two plates. When a voltage is applied to the two plates, a current will flow and the capacitor will charge until the two plates are at the same voltage.

In terms of capacity, B32671P4224J289 has a capacitance of 4.2uF at nominal voltage of 25V DC. It also features a high ripple current handling capability, with a leakage current of 0.3mA at 40°C. Moreover, it has a high insulation resistance of >100GΩ, and a robust operating temperature of -40°C to +85°C. These features make it very suitable for a variety of applications.

The B32671P4224J289 is especially well-suited for applications that require high frequency operation and efficiency. It can also be applied in audio equipment, such as loudspeakers and portable audio devices, although their use in audio equipment is generally limited due to their low capacitance. Furthermore, this product is also compatible with the requirements set by major safety standards such as IEC 60384-14, derating and UL.

Overall, the B32671P4224J289 is an excellent choice for high frequency applications, such as AC/DC coupling or power conditioning. Its wide temperature range and high insulation resistance make it suitable for a range of applications. Furthermore, its non-inductive construction provides superior performance in high frequency applications, making it an ideal choice for such applications.
