• High ripple capability: Rated ripple current of 11 A at 120 Hz and 15.4 A at 100 kHz, supporting demanding AC ripple and switching-frequency stresses.
• Long life endurance: Specified for 20,000 hours at +85°C when subjected to rated ripple current, enabling extended service in continuous-operation environments.
• Package & mounting: Radial can with screw terminals provides secure electrical connections and straightforward mechanical mounting for industrial assemblies.
• Operating range & polarization: Polarized capacitor with an operating temperature range of −25°C to +85°C and defined low-temperature impedance behavior.
• Environmental compliance & options: RoHS compliant; flame-retardant electrolyte option is available within the series.
• Physical size: Can size φ63.5 with dimensions L: 15.0 cm × D: 6.35 cm for planning PCB and chassis layouts.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing for inverter-driven power supplies and industrial converters where high voltage and ripple tolerance are required.
• Inverter circuitry: DC link and filtering roles in inverter sections, benefiting from the capacitor’s high ripple current rating and long endurance at elevated temperature.
• High-voltage power conversion: Use in extra-high-voltage smoothing and decoupling in power conversion systems that need sustained performance under continuous load.
• General-purpose power systems: Applications that demand reliable polarized aluminum electrolytic capacitors with predictable leakage and impedance behavior across temperature.

Unique Advantages

• Extended operational life: 20,000 hours at +85°C under rated ripple current reduces replacement frequency and supports continuous industrial operation.
• High ripple handling: 11 A (120 Hz) and 15.4 A (100 kHz) ripple ratings accommodate both low-frequency and switching-frequency stress without compromising performance.
• Extra‑high voltage capability: 400 V rating enables use in higher-voltage DC link and power conversion designs without multiple-parallel workarounds.
• Screw-terminal robustness: Radial can with screw terminals provides reliable, low-impedance connections suitable for heavy-current paths and secure mounting.
• Predictable electrical limits: Leakage current specification (≤ 3√CV μA or 5 mA after 5 minutes) and defined low-temperature impedance behavior support reliable design margining.
• Regulatory and safety options: RoHS compliance and availability of flame-retardant electrolyte types help meet environmental and safety requirements.
