Urms=350Vac”used in 277Vac power supply voltage

“Urms=300Vac” as the power supply voltage fluctuation. The maximum a.c voltage is 300Vac, which is the maximum voltage when the power supply voltage (rated voltage is 240Vac) is in a fluction instead of the guarantee of a continuous voltage value.

◆ Product Advantages
• Excellent Self-Healing for Safety and Reliability: Using metallized polypropylene film with industry-leading self-healing capability, localized breakdown is instantly self-repaired, preventing complete failure from localized defects and significantly enhancing safety redundancy in AC filter systems
• Non-Inductive Winding Structure: Special non-inductive film winding process effectively suppresses high-frequency parasitic inductance, ensuring accurate LC or LCL resonant frequency and superior filtering characteristics
• Plastic Case with Full Epoxy Resin Sealing: UL94-V0 flame-retardant housing with full epoxy resin sealing provides moisture-proof and dust-proof protection with high mechanical strength, suitable for direct integration into PCBs or power modules
• Specially Optimized for Small-Power AC Filtering: Purpose-optimized for small-power AC output filter applications with excellent harmonic suppression and compact form factor

◆ Key Selling Points
• Precisely Suited for LCL Filter Architecture: Widely used in grid-connected inverter LCL filter circuits, helping to meet grid-connected harmonic current limit requirements (IEEE 1547, IEC 61727)
• Low Loss and Minimal Heat Generation: Low tanδ value ensures controlled temperature rise during prolonged AC current conduction without affecting surrounding components
• Multiple Lead Configurations: Various lead pitch and height specifications to accommodate different PCB design requirements
• International Certification Compliance: Meets IEC 61071, UL810, and other certification requirements

◆ Primary Applications
• LCL output filtering for photovoltaic grid-connected inverters
• AC filtering for small wind power inverters
• AC-side EMI filtering for industrial frequency converters
• UPS inverter output stage filtering
• Power circuits for Active Power Filters (APF)
