LNR1E224MSEN

The LNR1E224MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNR series. It delivers very large bulk capacitance in a radial can with screw terminals, targeting general‑purpose power applications that need high energy storage and robust connections.

Key value propositions include 220,000 µF (220 mF) capacitance at 25 V, high ripple current capability across low and high frequencies, and extended endurance rated for 5,000 hours at 85°C—making it suitable for designs that require sustained smoothing, hold‑up, or energy buffering under continuous load.

Key Features

• High Capacitance — 220,000 µF (220 mF) nominal capacitance provides substantial bulk energy storage for power smoothing and hold‑up.
• Rated Voltage — 25 V rated voltage suitable for a wide range of low‑voltage DC systems.
• Screw‑Terminal Mounting — Robust screw terminals (radial can, screw terminals) for secure, low‑impedance connections in heavy‑current applications.
• High Ripple Current Handling — Low‑frequency ripple current of 18.9 A (120 Hz) and high‑frequency ripple current of 21.73 A (100 kHz) to support continuous ripple duty across a broad frequency range.
• Loss Characteristics — tanδ (DF) of 0.65 measured at 20°C, 120 Hz for predictable AC loss behavior.
• Leakage Current — Specified leakage current up to 5,000 µA (5 mA) after application of rated voltage.
• Endurance — Rated life of 5,000 hours at 85°C with defined limits: capacitance change within ±15%, tanδ ≤175% of initial, and leakage current ≤ initial specified value after endurance testing.
• Operating Temperature — Wide operating range from −40°C to +85°C for diverse environmental conditions.
• Compact Radial Can — Body diameter φ63.5 mm × length 120 mm provides high capacitance in a controlled form factor; packaged in cardboard for shipment.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and energy buffering where high capacitance and high ripple current capability are required.
• DC Link and Power Conditioning — Energy storage and ripple attenuation in DC link circuits and power conditioning stages operating at up to 25 V.
• Industrial Equipment — Long‑life smoothing and hold‑up in industrial control and power electronics that operate within −40°C to +85°C.

Unique Advantages

• Substantial Bulk Energy Storage: 220,000 µF provides large capacitance for extended hold‑up and smoothing, reducing the need for parallel components.
