LNR2A473MSEN

The LNR2A473MSEN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines high capacitance (47 mF) at a 100 V rating with a robust screw-terminal radial can package to support high-current and high-energy buffering in industrial and power-electronic designs.

Key value propositions include large capacitance for bulk energy storage, high allowable ripple current, long endurance at elevated temperature, and an operating range suitable for common industrial environments.

Key Features

• High Capacitance — 47 mF (47,000 µF) nominal capacitance provides substantial bulk energy storage for smoothing and buffering in DC power systems.
• Rated Voltage — 100 V nominal voltage rating for higher-voltage power rails and energy storage applications.
• Low Loss (tan δ) — Specified tanδ of 0.2 (measured at standard conditions) to characterize dissipation and AC loss behavior.
• Leakage Current — Specified leakage current of 5,000 µA (5 mA), suitable for designs that tolerate moderate quiescent leakage.
• High Ripple Current Capability — 14.4 A at 120 Hz and 16.56 A at 100 kHz, supporting applications with significant ripple or switching stress.
• Endurance — Rated for 5,000 hours at 85°C under DC bias plus rated ripple current, with defined limits for capacitance change, tanδ, and leakage.
• Robust Mechanical Package — Radial can with screw terminals (φ63.5 × 140 mm body), M5 terminal hardware and available mounting brackets for secure connections.
• Wide Operating Temperature — −40°C to +85°C operating range for broad environmental compatibility.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy buffering on high-voltage DC rails to stabilize output and absorb transient loads.
• Industrial power electronics — DC bus and intermediate storage in converters and power-conditioning equipment where high capacitance and ripple handling are required.
• Uninterruptible power systems (UPS) and backup power — Energy storage for ride-through and hold-up time extension on higher-voltage systems.

Unique Advantages

• Large energy capacity: 47 mF at 100 V provides significant stored energy in a single unit, reducing the number of components required for bulk storage.
• High ripple tolerance: Rated ripple currents at both low and high frequencies allow use with both line-frequency and switching supplies.
• Durability at elevated temperature: 5,000-hour endurance at 85°C supports long-term operation under continuous load and temperature stress.
• Secure electrical connections: Screw-terminal radial can package with M5 terminals and bracket options for reliable mounting in industrial assemblies.
• Practical packaging and availability: RoHS-compliant unit shipped in cardboard packing and available in mass production quantities for volume deployments.
