• Long Endurance — Designed for 20,000 hours of operation at +85°C under rated ripple current, providing extended service life in demanding environments.
• Operating Temperature & Low-Temperature Stability — Rated for operation from −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) of 8, supporting stable performance across the specified range.
• Screw-Terminal Radial Can — Polarized, screw-terminal package (radial can) for secure electrical and mechanical connections in high-current assemblies; size dimension L: 17 × D: 7.62 cm.
• Safety & Compliance — Flame-retardant electrolyte versions available; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies (Inverter Circuits) — Used as DC-link and smoothing capacitors in inverter circuitry to handle high ripple currents and provide stable DC energy storage.
• High-Voltage Power Conversion — Suited for extra-high-voltage applications requiring bulk capacitance at 350 V for power conversion and filtering.
• General-Purpose Power Systems — Applicable where long-life, high-capacitance, polarized electrolytic solutions are needed for energy buffering and transient suppression.

Unique Advantages

• High Ripple Capability: Measured ripple ratings of 21.8 A (120 Hz) and 30.52 A (100 kHz) reduce thermal stress and improve stability in high-frequency power circuits.
• Extended Service Life: 20,000-hour endurance at +85°C under rated ripple current supports longer maintenance intervals and predictable lifecycle planning.
• Extra-High Voltage Support: 350 V rating (series range extends higher) enables use in higher-voltage DC-link applications without series stacking.
• Robust Screw-Terminal Connection: Screw terminals provide secure, low-resistance connections for heavy-current paths and simplify installation in power assemblies.
• Large Energy Storage in a Radial Can: 10,000 µF capacitance in a screw-terminal radial package (L: 17 × D: 7.62 cm) supplies substantial bulk energy for smoothing and hold-up.
• Regulatory and Safety Options: RoHS compliance and availability of flame-retardant electrolyte variants support regulatory and safety design requirements.
