◆ Product Advantages
• Non-Inductive Structure for Outstanding High-Frequency Performance: Metallized polypropylene film with non-inductive winding achieves extremely low equivalent series inductance (ESL), effectively suppressing voltage ripple in high-frequency DC filter applications and significantly improving power output quality
• Plastic Case with Epoxy Resin Encapsulation: UL94-V0 flame-retardant plastic housing with full epoxy resin sealing provides moisture-proof, vibration-proof, and corrosion-resistant protection for reliable operation in harsh industrial environments
• Direct Replacement for Electrolytic Capacitors: Can directly replace aluminum electrolytic capacitors in DC filter circuits — non-polarized, no liquid electrolyte, no risk of electrolyte dry-out, with service life far exceeding electrolytic capacitors
• PCB-Compatible Design: Standard lead pitch for direct PCB soldering simplifies circuit design and improves overall system reliability

◆ Key Selling Points
• High-Performance DC Filtering: Specifically designed for industrial power supplies, frequency converters, and solar inverters with stable filtering performance and strong ripple suppression capability
• Self-Healing Property for Long-Term Stability: Metallized film self-healing characteristic effectively handles occasional over-voltage events, ensuring long-term operational safety
• Wide Temperature Grade: Meets industrial-grade operating requirements from -40°C to +105°C
• RoHS Compliant: Lead-free and halogen-free materials meet international environmental standards

◆ Primary Applications
• DC bus filtering for industrial switching power supplies
• DC-side filtering for photovoltaic solar inverters
• Decoupling and filtering on the DC side of frequency converters
• High-end UPS uninterruptible power supplies
• Medical power supplies and precision instrument power filtering
