Film capacitors, also known as plastic film capacitors, are a type of capacitor that uses a thin plastic film as an insulator between the two electrodes of its charge-storing components. As film capacitors are able to provide good dielectric insulation properties, low dielectric absorption, and temperature stability,they are widely used in various applications such as ac-line filtering, coupling, and energy storage. The DPP4S15K-F is a film capacitor developed by Delta Electrical, tailor-made for demanding applications.

The DPP4S15K-F is an all-round device, designed for a variety of different applications. It is an ultralow-profile and highly reliable device, with a rated voltage of 800V DC and a capacitance of 15,000uF. Its high ripple current capability and long life make it a great choice for applications where long-life performance is of paramount importance. Its low ESR and excellent frequency characteristics also make it highly suitable for use in pulse circuits.

In terms of its application field, the DPP4S15K-F is ideal for use in automotive electronics, as it is rated as an AEC-Q200 compliant device. It can be used in applications such as power steering, braking and ignition systems, as it is capable of withstanding temperature variations and high vibration levels. It is also suitable for energy storage systems, particularly high efficiency ones, due to its low ESR and high ripple current capability. Additionally, it is widely used in industrial equipment, electric drives and drives, and UPS.

The core of the DPP4S15K-F is the plastic film in between the electrodes which store the charge. This film is typically made from polypropylene, polycarbonate, polyester, polystyrene, or a combination thereof. The temperature range of the film can range from -55C to +125C for the common materials, allowing the capacitor to operate in extreme conditions.

The DPP4S15K-F works by storing an electric charge inside its electrodes. When a voltage potential exists across the electrodes, electrons are drawn to the positive electrode, and the capacitor builds up a charge in the form of an electrostatic field. This charge causes a current flow between the electrodes, which stores energy in the form of the electrostatic field. The stored charge in the capacitor is released when the potential between the electrodes is reversed, allowing for the current to discharge in the opposite direction.

The DPP4S15K-F is a great device due to its capable performance in various applications and its excellent reliability. Its high ripple current capability, low ESR, and temperature stability make it a great choice for most applications needing reliable long-term performance. Its use in energy storage systems and automotive electronics makes it a versatile and highly desirable device.
