LNR1V474MSEB

The LNR1V474MSEB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, providing 470,000 µF (470 mF) capacitance at a rated voltage of 35 V. Designed for general-purpose power applications, it delivers high bulk capacitance, substantial ripple-current capability, and a long 5,000-hour endurance at 85°C.

This radial, can-style capacitor with screw terminals is suited for applications that require large energy storage and high ripple handling in ambient conditions from −40°C to +85°C. The part is RoHS-compliant and available in mass production packing (cardboard).

Key Features

• High Bulk Capacitance — 470,000 µF (470 mF) provides significant energy storage for smoothing and bulk decoupling in power systems.
• 35 V Rated Voltage — Rated for operation at 35 V, enabling use in many mid-voltage power applications.
• Screw-Terminal Mounting — Robust screw terminal (radial can with screw terminals) for secure, high-current connections and easy installation.
• High Ripple Current Capability — 32.6 A at 120 Hz and 37.49 A at 100 kHz, supporting substantial AC stress in power-conversion environments.
• Endurance and Reliability — Rated life of 5,000 hours at 85°C with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Electrical Characteristics — Tolerance ±20% (at 120 Hz, 20°C), tan δ 0.9, and leakage current specified at 5,000 µA (5 mA).
• Wide Operating Temperature Range — Specified to operate from −40°C to +85°C.
• Form Factor — Large-format can: diameter ~90 mm × length ~170 mm (L: 17 × D: 9 cm), suitable for chassis-mounted power modules; supplied with standard 3-leg mounting brackets on larger diameters as per series guidelines.
• RoHS Compliant & Production Ready — Conforms to RoHS regulations and available in mass-production quantities with cardboard packing.

Typical Applications

• Power Supplies — Bulk smoothing and energy storage for AC/DC and DC/DC converters where large capacitance and ripple handling reduce voltage ripple and improve hold-up time.
• DC Link & Inverter Systems — DC-link energy reservoir in inverters and motor-drive systems requiring high ripple current capability and long endurance at elevated temperatures.
• Industrial Power Electronics — Energy buffering and transient suppression in industrial power modules, UPS systems, and large-scale power assemblies that use screw-terminal capacitors for secure connections.

Unique Advantages

• Large Energy Storage: 470,000 µF capacitance provides substantial bulk capacitance to stabilize DC rails and support transient demands.
• High Ripple Handling: Rated ripple currents (32.6 A at 120 Hz, 37.49 A at 100 kHz) enable operation under heavy AC stress without immediate degradation.
• Robust Mechanical Termination: Screw-terminal mounting simplifies high-current wiring and improves mechanical reliability in power assemblies.
• Durability at Elevated Temperature: 5,000-hour life at 85°C offers predictable endurance for designs exposed to sustained high ambient temperatures.
• Clear Electrical Limits: Specified leakage current (5,000 µA), tan δ (0.9), and ±20% tolerance provide measurable parameters for design and derating.
• Production-Ready Packaging: RoHS-compliant and shipped in cardboard packing for straightforward integration into production supply chains.
