LNY2W103MSEHBN

The LNY2W103MSEHBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNY series, delivering 10000 µF at a 450 V rating. Designed as a high-capacitance, high-voltage radial can with screw terminals, it targets general-purpose power applications where elevated ripple tolerance and compact energy storage are required.

Key value propositions include high ripple-current capability at both low and high frequencies, a 2000-hour endurance at 85°C, RoHS compliance, and a form factor suited for equipment downsizing.

Key Features

• High Capacitance & Voltage: 10000 µF rated capacitance at 450 V for bulk energy storage and DC link applications where large capacitance and high voltage are needed.
• Screw Terminal Mounting: Robust radial can with screw terminals (M5 bolt nominal) for secure electrical and mechanical connections in high-current assemblies.
• High Ripple Current Handling: Rated ripple current of 23 A at 120 Hz and 32.2 A at 10 kHz, enabling sustained AC ripple absorption across common power frequencies.
• Temperature & Lifetime: Operating range −40°C to +85°C with a rated load life of 2000 hours at 85°C when subjected to rated ripple current.
• Leakage & Loss Characteristics: Specified leakage current of 5000 µA and a tangent of loss angle (tanδ) of 0.25, allowing designers to assess dissipation and leakage under rated conditions.
• Construction & Packaging: φ76.2 × 210 mm (L: 21 cm × D: 7.62 cm) radial can with screw terminals, shipped in cardboard packing and available in mass production quantities.
• Quality & Safety Characteristics: Insulation resistance of more than 100 MΩ at DC 500 V between terminal and bracket and withstands AC 2500 V for 1 minute between terminal and bracket.

Typical Applications

• General Purpose Power Systems: Bulk energy storage and smoothing in power supplies and industrial converters where high capacitance and high voltage are required.
• High-Ripple Environments: Use in assemblies that require sustained ripple handling at both low (120 Hz) and high (10 kHz) frequencies.
• Equipment Downsizing: Suitable where designers aim to increase stored energy per package volume to reduce overall equipment size while maintaining performance.

Unique Advantages

• Large Stored Energy in a Single Can: 10000 µF at 450 V reduces the need for multiple parallel units, simplifying BOM and assembly complexity.
• High Ripple Endurance: Rated ripple currents of 23 A (120 Hz) and 32.2 A (10 kHz) support demanding power filtering and smoothing requirements without frequent replacements.
• Durable Screw-Terminal Interface: Screw terminals with M5 nominal bolt sizing provide reliable mechanical retention and low-resistance current paths for high-current circuits.
• Temperature-Rated Reliability: Specified −40°C to +85°C operation and a 2000-hour life at 85°C provide predictable performance in elevated-temperature installations.
• Electrical Safety Margins: High insulation resistance and a 2500 V AC voltage-proof test between terminal and bracket contribute to safe integration into high-voltage systems.
• Regulatory Compliance: RoHS-compliant construction supports use in regions and projects requiring hazardous-substance restrictions.
