LNR2E333MSEB

The LNR2E333MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It offers 33,000 µF capacitance at a 250 V rating with high ripple-current capability and a robust 5,000-hour endurance at 85°C.

Built for bulk energy storage and heavy-duty filtering in 250 V circuits, this Nichicon LNR-series part combines large capacitance, high ripple tolerance, and screw-terminal mounting for secure electrical connection in industrial and commercial equipment.

Key Features

• High Capacitance and Voltage: 33,000 µF nominal capacitance with a 250 V rated voltage, providing substantial bulk energy storage for DC systems.
• Rated Tolerance: Capacitance tolerance of ±20% at 120 Hz, 20°C for predictable sizing and design margin.
• High Ripple Current Handling: Low-frequency ripple current 19.7 A (120 Hz) and high-frequency ripple current 23.64 A (100 kHz), enabling effective smoothing under significant AC ripple conditions.
• Endurance and Reliability: Rated life of 5,000 hours at 85°C under DC bias plus rated ripple current; capacitance change remains within ±15% after endurance testing as specified in the series datasheet.
• Leakage Current: Specified leakage current 5,000 µA (with datasheet guidance that leakage is measured after 5 minutes’ application of rated voltage and follows the manufacturer’s leakage-current criteria).
• Temperature Range: Operating from −25°C to +85°C for the 160–250 V range, suitable for typical industrial ambient conditions.
• Screw Terminal Mounting: Radial can with screw terminals (φ90 × 220 L) and standard bracket mounting for secure, low-resistance connections in panel- or chassis-mounted applications.
• RoHS Compliant & Mass Production: RoHS status compliant and listed as mass production, suitable for production deployments; packaged in cardboard packing.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in 250 V DC rails where high capacitance and ripple current capability are required.
• DC Link and Drive Circuits — Energy buffering and ripple suppression in inverter and motor-drive power electronics that operate at or near 250 V.
• Uninterruptible Power Supplies (UPS) and Power Conditioning — Bulk capacitance for hold-up and filtering in commercial and industrial backup systems.
• High‑power Commercial Equipment — General-purpose power filtering and energy storage in large-format equipment that benefits from screw-terminal mounting and long endurance at elevated temperature.

Unique Advantages

• Substantial Energy Density: 33,000 µF at 250 V provides significant bulk storage for DC rails, reducing the number of parallel components required.
• Robust Ripple Performance: High low- and high-frequency ripple ratings (19.7 A at 120 Hz, 23.64 A at 100 kHz) enable reliable operation under heavy AC ripple loads.
• Designed for Long Service Life: 5,000-hour endurance at 85°C under rated conditions with controlled capacitance drift and leakage behavior.
• Secure Screw-Terminal Interface: Radial can with screw terminals simplifies high-current connections and mechanical retention in chassis-mounted designs.
• Clear Thermal Specification: Specified operating range of −25°C to +85°C for use across typical industrial ambient conditions in the 160–250 V band.
• Regulatory Compliance and Production Readiness: RoHS-compliant and in mass production, packaged for shipment in cardboard packing.
