LNR2E473MSE

The LNR2E473MSE is a screw-terminal aluminum electrolytic capacitor engineered for high-capacitance, high-voltage general-purpose power applications. With a rated capacitance of 47,000 µF and a 250 V rating, this radial can with screw terminals delivers bulk energy storage and robust ripple handling for industrial power systems and power conditioning modules.

Key value propositions include high ripple-current capability across low and high frequencies, long endurance at elevated temperature, and a screw-terminal package designed for secure connections and high-current power paths.

Key Features

• High Capacitance (47,000 µF) — Large bulk capacitance for energy storage and smoothing in high-voltage DC circuits.
• 250 V Rated Voltage — Suitable for applications requiring up to 250 V DC continuous operation.
• Screw Terminal, Radial Can Package — Robust screw-terminal mounting for secure electrical and mechanical connections; radial can with screw terminals simplifies assembly in power racks.
• High Ripple Current Capacity — 21.2 A at 120 Hz (low frequency) and 25.44 A at 100 kHz (high frequency), enabling effective handling of both mains-frequency and switching-frequency ripple currents.
• Endurance at Elevated Temperature — Rated for 5,000 hours at 85°C with specified limits on capacitance change (within ±15%), tanδ (≤175% of initial), and leakage current (≤ initial specified value).
• Low Loss Characteristic — Tangent of loss angle (tanδ) specified at 0.25 (20°C, 120 Hz), supporting efficient energy transfer with controlled dissipation.
• Controlled Leakage Current — Specified leakage current of 5,000 µA (per product data), consistent with large-value, high-voltage aluminum electrolytic designs.
• Operating Temperature Range — Rated for operation from −25°C to +85°C for the 160–250 V class.
• Regulatory and Packaging — RoHS compliant and supplied in cardboard packing for mass-production deployments.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing where a high 47,000 µF capacitance and 250 V rating are required to stabilize DC rails.
• DC-Link and Inverter Systems — Use in DC-link or intermediate circuits that demand high ripple-current capability at both mains and switching frequencies.
• UPS and Power Conditioning — Energy buffering and ripple attenuation in uninterruptible power supplies and conditioning modules for industrial equipment.

Unique Advantages

• Large Energy Storage in a Single Component: 47,000 µF capacitance reduces the need for parallel arrays, simplifying BOM and layout for high-capacitance DC sections.
• High Voltage and Ripple Headroom: 250 V rating combined with 21.2 A (120 Hz) and 25.44 A (100 kHz) ripple ratings supports demanding power stages and reduces thermal stress on adjacent components.
• Durability at Elevated Temperature: 5,000-hour endurance at 85°C with bounded capacitance and loss changes gives predictable lifetime performance for sustained high-temperature operation.
• Secure, Serviceable Connections: Screw-terminal construction and radial can packaging enable robust mechanical mounting and straightforward field servicing or replacement.
• RoHS Compliant and Production-Ready: Environmentally compliant construction and cardboard packing suitable for mass-production workflows.
