LNR1H333MSEN

The LNR1H333MSEN is a Nichicon LNR series aluminum electrolytic capacitor in a screw-terminal radial can. It provides 33,000 µF capacitance at a 50 V rating with ±20% tolerance, designed for general-purpose power applications that require high bulk capacitance and secure terminal connections.

Key electrical and reliability attributes include high ripple-current capability (7.0 A at 120 Hz, 8.05 A at 100 kHz), low leakage current (3,850 µA), a specified tanδ of 0.25, and a rated endurance of 5,000 hours at 85°C. The unit operates over a −40°C to +85°C range and is supplied in cardboard packing.

Key Features

• Capacitance & Rated Voltage — 33,000 µF (33 mF) nominal capacitance at a 50 V rating with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage.
• High Ripple-Current Handling — Rated for 7.0 A low-frequency ripple at 120 Hz and 8.05 A high-frequency ripple at 100 kHz, supporting demanding AC ripple conditions on DC bus lines.
• Low Leakage & Defined Loss — Leakage current specified at 3,850 µA and tanδ of 0.25, enabling predictable standby and loss characteristics for power designs.
• Endurance at Elevated Temperature — Rated lifetime of 5,000 hours at 85°C under DC bias plus rated ripple current, with defined post-endurance limits for capacitance, tanδ, and leakage.
• Robust Mechanical Design — Screw terminal radial can package with φ51 × 70 mm body dimensions and standard 3-leg bracket furnishing for secure mounting and strong electrical connections.
• Wide Operating Temperature — Specified for operation from −40°C to +85°C, suitable for a broad range of ambient conditions within its rated voltage class.
• Regulatory & Packaging — RoHS-compliant construction and supplied in cardboard packing for handling and logistics.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing for DC bus rails where large capacitance and high ripple-current capability are required.
• Industrial power electronics — DC-link and decoupling in motor drives and inverter assemblies that benefit from secure screw-terminal connections and robust ripple handling.
• Backup and hold-up circuits — Energy storage for short-term hold-up and standby support, leveraging the capacitor’s high capacitance and endurance rating at 85°C.
• Renewable and commercial inverters — DC-link smoothing and ripple attenuation in commercial inverter systems requiring large-value electrolytic capacitors with proven lifetime characteristics.

Unique Advantages

• High bulk capacitance at moderate voltage — 33,000 µF at 50 V delivers substantial stored energy per component, reducing the number of parallel devices needed.
• Dual-frequency ripple performance — Separate ripple-current ratings for 120 Hz and 100 kHz clarify performance across low- and high-frequency ripple environments.
• Screw-terminal reliability — Robust screw terminals and radial can construction enable secure, low-impedance connections in assemblies subject to vibration or high current.
• Defined endurance and thermal rating — 5,000-hour life at 85°C with specified post-endurance limits gives predictable aging behavior for long-term designs.
• Predictable leakage and dissipation — Specified leakage current and tanδ support accurate power-loss budgeting and thermal management.
• RoHS compliant and packaged for handling — Environmentally compliant materials and cardboard packing simplify procurement and handling processes.
