LNR2E473MSEN

The LNR2E473MSEN is a screw‑terminal aluminum electrolytic capacitor rated at 250 V with 47,000 µF nominal capacitance and ±20% tolerance. It is a polarized, radial can design furnished for heavy‑duty power applications where bulk energy storage and high ripple handling are required.

Key value propositions include high allowable ripple current (21.2 A at 120 Hz and 25.44 A at 100 kHz), a long endurance rating of 5,000 hours at 85 °C, robust screw‑terminal mounting (M8 for the φ100 body) and RoHS compliance. The capacitor is supplied in cardboard packaging and is in mass production.

Key Features

• High Capacitance & Voltage — 47,000 µF nominal capacitance at a 250 V rated voltage provides large bulk energy storage in a single device.
• High Ripple Current Capability — Rated ripple current of 21.2 A at 120 Hz and 25.44 A at 100 kHz supports heavy AC ripple and high‑frequency decoupling requirements.
• Endurance at Elevated Temperature — Designed for 5,000 hours endurance at 85 °C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current after test.
• Controlled Dissipation Factor — tan δ of 0.25 (20 °C, 120 Hz) supports predictable loss and thermal behavior in power designs.
• Screw Terminal Mechanical Design — Radial can with screw terminals and M8 nominal bolt for the φ100 body ensures secure, low‑impedance connections for high‑current installations; standard supply includes a 3‑leg mounting bracket for larger diameters.
• Operating Range & Leakage — Polarized device with operating temperature range from −25 °C to +85 °C and specified leakage current up to 5,000 µA (5 mA).
• Packaging & Production — Supplied in cardboard packing and available in mass production quantities for volume deployment.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Industrial Power Supplies — Large capacitance and high ripple current ratings make this capacitor suitable for bulk smoothing and hold‑up in industrial DC power supplies.
• UPS and Inverter Systems — High energy storage at 250 V and endurance at 85 °C support DC bus stabilization and energy buffering in backup power and inverter designs.
• Motor Drives and Power Conversion — Robust screw‑terminal mounting and high allowable ripple current help manage pulsating loads and switching currents in motor drives and converters.
• Large‑Scale Energy Reservoirs — The combination of 47,000 µF capacitance and durable mechanical mounting supports use as a single‑component reservoir in heavy‑duty power systems.

Unique Advantages

• Single‑Component Bulk Storage: 47,000 µF at 250 V reduces the number of parallel capacitors required, simplifying BOM and assembly for large energy requirements.
• High Ripple Endurance: 21.2 A (120 Hz) and 25.44 A (100 kHz) ripple ratings allow reliable operation under both low‑ and high‑frequency ripple conditions.
• Long Life at Elevated Temperature: 5,000 hours rated life at 85 °C provides predictable performance and maintenance intervals for industrial deployments.
• Secure, Low‑Resistance Connections: Screw terminal design with M8 nominal bolt and standard 3‑leg bracket for the φ100 body offers durable, low‑impedance electrical and mechanical connections.
• Measurable Loss Characteristics: Specified tan δ (0.25 at 20 °C, 120 Hz) enables predictable thermal and loss calculations during system design.
• Production Availability: Cardboard packed and in mass production, supporting volume procurement and consistent supply.
