◆ Product Advantages
- Aluminum Alloy Case with High Mechanical Strength and Vibration Resistance: High-strength aluminum alloy cylindrical or rectangular housing provides excellent mechanical strength and strong resistance to vibration and shock, suitable for harsh vibration environments in industrial sites and new energy equipment with high protection ratings
- Dry-Type with No Liquid Dielectric: Unlike oil-filled capacitors, the dry-type structure completely eliminates the risk of liquid leakage, environmentally friendly and fully aligned with modern industrial equipment's clean operation requirements, with minimal maintenance costs
- Low ESR with High Ripple Current Capability: Extremely low equivalent series resistance enables handling of significant ripple currents in DC bus filter applications with controlled temperature rise, effectively reducing switching losses in frequency converters and inverters
- Self-Healing Property for Long-Term Reliability: Metallized film self-healing characteristic handles occasional over-voltage events, ensuring long-term stability of the DC filter circuit and meeting industrial-grade high-reliability requirements
- Low Inductance (Ls) Design: Non-inductive winding process minimizes parasitic inductance, suppressing high-frequency di/dt impulses and protecting power switching devices from surge damage

◆ Key Selling Points
- Wide Compatibility with New Energy and Industrial Variable Frequency Applications: Proven for DC bus filtering in wind power generation, photovoltaic inverters, electric vehicles, and industrial frequency converters with extensive application coverage
- Aluminum Case Available in Multiple Size Specifications: Various diameter and height specifications available to flexibly match different chassis and installation space requirements
- Excellent Heat Dissipation Performance: Good thermal conductivity of aluminum housing assists capacitor heat dissipation, particularly advantageous in high ripple current applications
- Customer Customization Support: Capacitance, voltage rating, terminal configurations, and mounting dimensions can all be customized according to customer requirements
- Fully Sealed Dry-Type Structure: No liquid dielectric eliminates leakage contamination risk, with strong environmental adaptability and extremely low maintenance costs

◆ Primary Applications
- DC bus filtering for wind power generation converters
- DC-Link filtering for photovoltaic grid-connected inverters
- Main drive inverters for electric and hybrid electric vehicles
- Inverter power supplies for industrial welding equipment
- DC filtering for elevator and crane variable frequency drives
