LNR1A224MSEN

The LNR1A224MSEN from Nichicon is a screw-terminal aluminum electrolytic capacitor delivering 220000 µF (220 mF) of bulk capacitance at 10 V with ±20% tolerance. It is a radial, can-style, polarized capacitor designed for general-purpose power applications that require high capacitance, high ripple-current capability and a robust screw-terminal connection.

Key value propositions include high ripple-current handling at both low and high frequencies, long endurance at elevated temperature, and a compact φ51×100 mm form factor with screw terminals for secure electrical and mechanical mounting.

Key Features

• High Capacitance: 220000 µF (220 mF) rated capacitance for substantial bulk energy storage and smoothing in power systems.
• Rated Voltage & Tolerance: 10 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C.
• High Ripple Current Capability: 13.0 A low-frequency ripple current (120 Hz) and 14.95 A high-frequency ripple current (100 kHz) to support demanding ripple conditions.
• Endurance & Temperature Range: 5000 hours rated life at 85°C and operating temperature range of –40°C to +85°C.
• Electrical Loss & Leakage: Tangent of loss angle (tan δ) specified at 0.9 and initial leakage current of 4440 µA.
• Robust Mechanical Package: Radial, can-style body with screw terminals (φ51×100 mm body dimensions; L:10 × D:5.1 cm) for secure mounting; φ51 screw-terminal types typically use M5 nominal bolt diameter.
• Compliance & Packaging: RoHS-compliant with cardboard packing and listed as mass production status.

Typical Applications

• General-Purpose Power Conditioning: Provides bulk capacitance and ripple smoothing where a large-value polarized electrolytic is required.
• High-Ripple Environments: Suitable for circuits that impose substantial AC ripple due to its rated ripple-current performance at 120 Hz and 100 kHz.
• Secure-Screw-Terminal Installations: Ideal where a mechanically robust screw-terminal connection is needed for reliable electrical and mechanical retention.

Unique Advantages

• Significant Bulk Storage: 220000 µF capacity delivers large stored charge for smoothing and buffering functions.
• Dual-Frequency Ripple Handling: Rated ripple current values at 120 Hz and 100 kHz support both low-frequency and high-frequency ripple scenarios.
• Long Endurance at Elevated Temperature: 5000 hours at 85°C offers predictable performance over extended operational periods.
• Robust Screw-Terminal Connectivity: Screw-terminal package with φ51 body provides secure electrical connection and mechanical stability in equipment assemblies.
• RoHS Compliant: Meets RoHS requirements to support regulatory and environmental objectives.
