Plastic Case Dry Type DC-Link Automotive Capacitors

◆ Product Advantages
• Specifically Designed for New Energy Vehicle DC Bus: Deeply optimized for high-voltage DC bus filtering requirements in battery electric vehicles (BEV) and hybrid electric vehicles (HEV), capable of directly replacing large-capacity aluminum electrolytic capacitors with a non-polarized design that completely eliminates electrolyte leakage risk
• Extremely Low Equivalent Series Resistance (ESR): ESR values significantly lower than electrolytic capacitors result in minimal temperature rise under high-frequency ripple currents, supporting higher ripple current amplitudes and reducing inverter switching losses
• Low Equivalent Series Inductance (Ls): Non-inductive winding structure minimizes parasitic inductance, suppressing high-frequency oscillations and voltage spikes to protect power semiconductor IGBT/MOSFET devices from surge damage
• Excellent Self-Healing Performance: Metallized film self-healing characteristic handles occasional over-voltage events, consistent with high reliability requirements of automotive applications
• Plastic Case with Resin Filling: Lightweight design with vibration and weather resistance, adapting to harsh vibration and temperature environments of automotive chassis and engine compartments

◆ Key Selling Points
• Long Service Life Matching Vehicle Lifetime Requirements: Design life target exceeding 15 years/500,000 km under automotive operating conditions, far surpassing electrolytic capacitors
• AEC-Q200 Grade Quality Validation: Validated against automotive electronics reliability standards, suitable for direct adoption by OEM vehicle manufacturers
• Supports Customized Development: Capacitance, voltage, mounting dimensions, and connector interfaces can be customized according to vehicle manufacturer parameters
• Multi-Energy Adaptability: Also applicable to wind and solar power generation inverters and welding equipment inverter power supplies"

◆ Primary Applications
• DC bus filtering for main inverters in battery electric vehicles (BEV) and hybrid electric vehicles (HEV/PHEV)
• DC filtering for on-board chargers (OBC)
• Wind and solar power generation inverters
• Elevator and motor drive frequency converters
• Industrial welding equipment inverter power supplies
