LNR1K333MSE

The LNR1K333MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, rated 80 V with 33,000 µF nominal capacitance. Built as a radial can with screw terminals, it delivers high bulk capacitance and robust mechanical mounting for general-purpose power applications.

Designed for use across a broad range of equipment, the part offers long life at elevated temperature and measurable ripple handling, making it suitable for systems that require substantial energy storage and stable DC filtering.

Key Features

• Capacitance & Voltage — 33,000 µF nominal capacitance at a rated voltage of 80 V, with ±20% tolerance at 120 Hz, 20°C.
• Mounting & Package — Screw terminal radial can package (φ51 × 120 mm body) for secure bolted connections and straightforward system integration.
• Electrical Performance — Specified tan δ of 0.2 and leakage-current specification from the series datasheet (after 5 minutes, not more than 3√CV µA or 5 mA, whichever is smaller), supporting predictable behavior in DC-bias applications.
• Ripple Current Capability — Rated ripple current of 9.2 A at 120 Hz and 10.58 A at 100 kHz, enabling effective smoothing under both low- and high-frequency ripple conditions.
• Temperature & Lifetime — Operating range −40°C to +85°C with an endurance rating of 5000 hours at 85°C under DC bias plus rated ripple current.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supply smoothing — Bulk capacitance for DC-link and post-regulation filtering in general-purpose power supplies.
• Bulk energy storage — Large capacitance for energy buffering where reliable discharge and recharge cycles are needed in general industrial equipment.
• Power conditioning — Smoothing and ripple reduction in systems that require stable DC rails across a wide temperature range.

Unique Advantages

• High bulk capacitance: 33,000 µF provides substantial energy storage for smoothing and decoupling, reducing the need for multiple smaller parts.
• Screw-terminal reliability: Robust bolted connections simplify installation and improve mechanical stability in vibration-prone environments.
• Measurable ripple handling: Defined ripple current ratings at 120 Hz and 100 kHz allow designers to size the capacitor confidently for expected ripple profiles.
• Extended life at elevated temperature: 5000 hours endurance at 85°C under rated conditions supports longer maintenance intervals and predictable aging.
• Wide operating range: −40°C to +85°C operation suits deployments across varied ambient conditions.
• Regulatory compliance: RoHS status provides environmental conformity for mainstream equipment installations.
