Ducati 416.74.7054 is a power electronic capacitor featuring metallized polypropylene film dielectric
Ducati 416.74.7054 is a power electronic capacitor featuring metallized polypropylene film dielectric, mainly serving for energy storage, voltage stabilization, high - current filtering, and resonant tuning in power electronic circuits. It has low equivalent series resistance (ESR), low self - inductance, and high current handling capacity, making it ideal for applications requiring efficient energy transfer and minimal power loss.
Key Functional Traits
- Energy Storage and Voltage Smoothing: Stores electrical energy and releases it when needed to stabilize voltage fluctuations in DC - link circuits, reducing ripple and ensuring stable operation of power electronic devices.
- High - Performance Filtering: Low ESR (<2.0 mΩ) and low self - inductance (<200 nH) enable effective filtering of high - frequency noise and harmonics in power conversion circuits, improving power quality.
- Resonant Circuit Operation: Suitable for resonant circuits in power electronics, aiding in achieving efficient energy transfer and soft switching, which lowers switching losses and enhances system efficiency.
- High Current Handling: Capable of withstanding a maximum current of 40 A at 50°C ambient temperature, suitable for high - power applications with large current surges.
- Self - healing: The metallized polypropylene film dielectric has a self - healing property. In case of a dielectric breakdown, the metal electrode around the fault area vaporizes, isolating the fault and preventing short - circuits, thus improving reliability.
