DME2S56K Application Field and Working Principle

Film capacitors are widely applied in today’s market from audio-video applications to power electronic systems. The DME2S56K series of Film Hybrid Capacitors is a robust, reliable solution for a wide range of applications, particularly when requirements for longevity and operational temperature are demanding. In this article, we will discuss the application field and explore the working principle of the DME2S56K.

Application Field

The DME2S56K is a high-performance, multi-functional film capacitor designed with a range of features and capabilities. It provides a stable, high-frequency performance as well as a superior high-temperature endurance which is ideal for use in a wide variety of markets and applications. It is a great choice for various types of equipment, such as power supplies, switching power supplies, semi-conductor equipment, UPS systems, cable TV systems, power supplies, transformers, and AC servo motors.

The DME2S56K also offers superior electrical insulation properties and wide temperature capability, making it suitable for a range of operation conditions. It is designed with a low ESR and low temperature coefficient, which make it suitable for automotive, consumer electronic, and medical applications. It is also designed to provide a low-profile and small-footprint, making it the perfect choice for compact consumer electronics and automotive systems.

Working Principle

The DME2S56K is a film capacitor with two layers of metal oxide layers that act as the dielectric layers. The inner metal oxide layer is made of aluminium oxide while the outer layer is made of titania. The two dielectric layers are arranged in a stack that forms the dielectric stack of the capacitor. This design provides a wide range of capacitance values while delivering excellent electrical properties.

The DME2S56K is designed to provide a high electric field strength, allowing it to achieve a high performance and reliability even in fluctuating or high-temperature operating conditions. The capacitance value of the DME2S56K is determined by the thickness of the two dielectric layers and their spacing. The aluminium oxide layer is much thicker than the titania layer, allowing it to provide greater capacitance values and to increase the stability of the capacitance.

The DME2S56K also features a low ESR and low impedance, making it suitable for applications such as DC-DC converters, Uninterruptible Power Supplies (UPS), and AC motor drives. The low ESR ensures that the capacitance value remains stable even under fluctuating load conditions, while the low impedance ensures that the capacitance remains low at low frequencies. The low impedance also provides an increased temperature rating, giving the DME2S56K excellent performance in extreme operating temperatures.

Conclusion

The DME2S56K Film Hybrid Capacitor is a reliable and robust solution for a wide range of applications. It provides excellent electrical properties and high-temperature endurance, allowing it to be used in a variety of markets and applications. It is designed to offer a high electric field strength, low ESR and low impedance, making it ideal for use in DC-DC converters, Uninterruptible Power Supplies (UPS), and AC motor drives.
