Key Features

• Capacitance & Rated Voltage – 2.7 mF (2700 µF) nominal capacitance at a rated voltage of 350 V with ±20% tolerance.
• Screw-Terminal Construction – Radial can package with screw terminals for secure, low-impedance connections in high-current applications.
• High-Speed Charge–Discharge – Designed for rapid charge–discharge cycles and regenerative voltage conditions commonly found in motor drives and inverters.
• Ripple Current Performance – Rated ripple current of 10.8 A at 120 Hz and 15.12 A at 100 kHz to support both low- and high-frequency load conditions.
• Temperature & Endurance – Operating range −25 °C to +85 °C with a rated endurance of 5000 hours at 85 °C under DC bias plus rated ripple current.
• Charge–Discharge Endurance – Meets series charge–discharge endurance requirements after 20 million cycles (ΔV = rated voltage × 0.3, 3 Hz cycle) with limits on capacitance change, tan δ, and leakage current.
• Leakage Current Specification – After 5 minutes at rated voltage, leakage current is specified as not more than 3√(V) µA or 5 mA, whichever is smaller.
• RoHS Compliance – Compliant with RoHS directives listed in the product data.
• Polarized Device – Polarized aluminum electrolytic capacitor suitable for DC power applications.

Typical Applications

• Inverter and Drive Systems – Energy buffering and regenerative voltage handling for AC servomotor and general inverter circuits.
• Regenerative Power Systems – High-frequency regenerative voltage suppression and energy storage in systems with frequent charge–discharge events.
• Rectifier / Voltage Doubler Circuits – Suited for rectifier circuits including voltage doubler topologies where robust DC smoothing is required.
• Industrial Equipment in Fluctuating Voltage Areas – Provides stable capacitance and endurance where supply voltages vary or experience transients.

Unique Advantages

• High ripple-current capability: Supports substantial ripple at both 120 Hz and 100 kHz, enabling use across low- and high-frequency power stages.
• Screw-terminal reliability: Durable screw terminals simplify installation and provide secure electrical and mechanical connections for high-current applications.
• Designed for rapid cycling: Specified charge–discharge endurance (20 million cycles at defined ΔV and cycle rate) reduces risk of premature degradation in regenerative applications.
• Long endurance at elevated temperature: 5000 hours at 85 °C under rated conditions offers predictable life performance for industrial environments.
• Clear leakage and loss specifications: Defined leakage-current limits and tan δ endurance limits allow predictable behavior in power designs and margin calculations.
• RoHS-compliant construction: Meets listed RoHS directives for environmental compliance in industrial equipment.
