Key Features

• Capacitance & Voltage — 10,000 µF (10 mF) nominal capacitance at a rated voltage of 350 V, providing substantial energy storage for DC-link and smoothing applications.
• Screw Terminal Package — Radial can with screw terminals for secure, high-current bolted connections suitable for industrial power systems.
• High Ripple Current Capability — Rated ripple currents of 31.1 A at 120 Hz and 43.54 A at 10 kHz to support high-frequency regenerative and inverter loads.
• Temperature & Endurance — Specified for operation from -25 °C to 85 °C with an endurance rating of 5000 hours at 85 °C under D.C. bias plus rated ripple current.
• Charge–Discharge Durability — Series-level charge–discharge endurance is demonstrated by meeting spec limits after 20 million cycles at specified ΔV and cycle conditions.
• Low-Temperature Stability — Impedance stability is characterized for low-temperature operation (Z(-25 °C) / Z(+20 °C) ≤ 8), aiding performance in colder environments.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• AC Servo Drives — Used in DC-link and regenerative stages to absorb and supply energy during frequent braking and acceleration cycles.
• General Inverters — Provides bulk energy storage and smoothing in inverter power stages exposed to high-frequency switching and regeneration.
• Voltage-Doubler Rectifiers — Suited for rectifier circuits such as voltage doubler topologies that require high-voltage electrolytic capacitance.
• Equipment in Fluctuating Voltage Areas — Designed for systems operating under variable or unstable mains where voltage excursions are common.

Unique Advantages

• High energy density for DC-link use: 10,000 µF at 350 V stores significant energy to stabilize DC bus rails and support regenerative events.
• Designed for high-frequency regenerative loads: High ripple current ratings at both 120 Hz and 10 kHz support fast charge–discharge cycles and inverter switching environments.
• Robust endurance profile: 5000 hours at 85 °C under rated conditions and proven charge–discharge endurance reduce the need for frequent replacements in demanding systems.
• Secure electrical connections: Screw-terminal radial can package provides reliable bolted connections for industrial power wiring and high-current paths.
• Stable across temperature extremes: Specified performance from -25 °C to 85 °C with a defined low-temperature impedance ratio supports a wide range of operating environments.
• Regulatory compliance: RoHS conformity simplifies material compliance for product development and deployment in regulated markets.
