Excellent electrical performance
It has extremely low equivalent series resistance (ESR) and parasitic inductance (ESL), which can effectively suppress high-frequency ripple current, reduce losses and heat generation, support high switching frequency operation, and improve the overall conversion efficiency of the machine.
Powerful voltage resistance and overcurrent capability
Using high-quality media such as metalized polypropylene film, combined with an enhanced electrode structure, it can withstand high DC voltage and high-frequency large ripple current, adapting to frequent power fluctuations and instantaneous impacts in inverter systems.
Good temperature stability
Within a wide temperature range of -40 ℃ to+105 ℃, the capacitance value changes little and the loss angle is stable. It is suitable for outdoor photovoltaic, vehicle inverters and other scenarios with large temperature differences and complex heat dissipation conditions.
High reliability and long service life
Through the use of seamless winding technology, flame-retardant epoxy encapsulation, and fully sealed metal shell design, it has excellent anti vibration, moisture-proof, and partial discharge resistance capabilities, with a typical lifespan of over 100000 hours, significantly reducing system maintenance requirements.
Compact structure and flexible installation
It can be designed as a cylindrical, flat, or modular structure according to the system layout, supporting various terminal forms such as screws, solder joints, and plugs, making it easy to achieve high power density integration in limited space.
