Film capacitors, known for their high reliability, have been gaining wide acceptance in various industrial and consumer applications. The DME4S15K is a new type of film capacitor manufactured by Deacon Components Inc. This capacitor has been developed specifically for high-performance, high-current applications such as power supplies and motor drives. It offers excellent electrical performance combined with a compact size.

The DME4S15K is a surface mounting film capacitor with a voltage rating of 4.7kV. It features a non-polarized construction, which means it can be connected with either the anode or the cathode lead. Additionally, the capacitor has a low ESR of 0.15 Ohm and a ripple current of 14A. These features make this capacitor suitable for applications that require high current and low voltage ripple.

The DME4S15K is constructed with a metalized film dielectric material. This material is a combination of metalized polyester and polypropylene which provides superior mechanical and electrical characteristics. The metalized film acts as the dielectric and provides excellent insulation against voltage spikes and breakdowns.

The DME4S15K offers excellent high-frequency performance and high frequency pulse loading capability. Additionally, it is capable of handling very high currents without exhibiting signs of failure. This makes the capacitor suitable for applications such as switch-mode power supplies, motor drives, and DC-DC converters.

Another advantage of the DME4S15K is its low height and wide operating temperature range. The capacitor has a height of 2.5mm and is rated for operation from -40°C to +125°C. This makes it ideal for space-constrained applications or high temperature environments.

The working principle of the DME4S15K is based on capacitive energy storage. When a varying voltage is applied to a capacitor, electric charges accumulate on the two plates of the capacitor. This stored energy can then be used for various applications. In a power supply, for example, the stored energy can be used to supplement the input voltage, resulting in improved system performance.

The DME4S15K is a high-performance film capacitor with excellent electrical characteristics, high-frequency performance, and wide operating temperature range. It is ideal for high current, low voltage ripple applications such as motor drives and power supplies. Additionally, its low height and wide operating temperature range make it suitable for space-constrained applications. The working principle of the capacitor is based on capacitive energy storage which makes it suitable for a variety of applications.
