• Screw‑Terminal Mounting (Radial Can): Robust screw‑terminal package intended for secure electrical and mechanical connections in power assemblies.
• High‑speed Charge/Discharge Capability: Designed for frequent charge/discharge cycles and high‑frequency regenerative voltage environments.
• Operating Temperature Range: Specified for −25 °C to +85 °C with endurance rated for 5000 hours at 85 °C, supporting continuous operation in elevated ambient conditions.
• Ripple Current Performance: Rated ripple current of 19.7 A at 120 Hz and 27.58 A at 10 kHz to support smoothing and regenerative loads.
• Capacitance Tolerance and Leakage: ±20% tolerance (at 120 Hz, 20 °C); leakage current per series specification: after 5 minutes at rated voltage, not more than 3√V (µA) or 5 mA, whichever is smaller.
• Series‑level Endurance and Cycle Life: Series specifications include 5000 h endurance at 85 °C and validated charge–discharge endurance (20 million cycles at ΔV = rated voltage × 0.3, 3 Hz) per the datasheet.
• RoHS Compliance: Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size: Package dimensions L: 11 cm × D: 7.62 cm (radial can with screw terminals).

Typical Applications

• AC servo and motor drives: Bulk DC‑link and regenerative energy capture for servomotor controllers where frequent charge/discharge and voltage swings occur.
• General inverters: DC bus filtering and smoothing in inverter front ends to handle ripple and transient energy during switching events.
• Rectifier / Voltage doubler circuits: Energy storage and smoothing in rectifier stages and voltage doubler topologies.
• Equipment in variable‑voltage environments: Systems exposed to fluctuating line voltages that require robust capacitance and endurance at elevated temperature.

Unique Advantages

• High energy storage at elevated voltage: 5.6 mF at 350 V supplies substantial DC bus energy without increasing series complexity.
