LNY2W103MSEHBB

The LNY2W103MSEHBB from Nichicon is a screw‑terminal, high‑capacitance aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 10 mF capacitance at a 450 V rated voltage and is part of the LNY series optimized for higher capacitance in compact assemblies.

Engineered for equipment downsizing and robust power handling, this capacitor combines high ripple current capability and a 2000‑hour load life at 85°C with RoHS compliance for regulated production environments.

Key Features

• Capacitance & Voltage — 10 mF capacitance rated at 450 V for high‑energy storage in DC link and bulk smoothing roles.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low‑impedance connections suitable for high current bus integration.
• High Ripple Current — 23 A at 120 Hz and 32.2 A at 10 kHz, enabling effective handling of AC ripple and high‑frequency stress in power stages.
• Temperature Range & Endurance — Operates from −40°C to +85°C with a specified load life of 2000 hours at 85°C under rated ripple current.
• Leakage and Insulation — Leakage current specified as not more than 3√CV (μA) or 5 mA after 5 minutes at 20°C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand — Withstands AC 2500 V for 1 minute between terminal and bracket with no abnormality, supporting safety margins in high‑voltage assemblies.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for regulated material use.
• Compact Package Options — Part of a series offering φD options and bracket mounting styles to support equipment downsizing; nominal dimensions for this part include L: 21 × D: 7.62 cm.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing at up to 450 V where high capacitance and high ripple current reduce voltage ripple on DC rails.
• Power conversion and DC link — DC link support for inverters and converters requiring robust high‑voltage capacitors with secure screw‑terminal connections.
• Equipment downsizing projects — High capacitance per package helps designers reduce overall system size while maintaining energy storage requirements.

Unique Advantages

• High energy density at 450 V — 10 mF rating provides substantial bulk capacitance for high‑voltage systems without resorting to large arrays of smaller parts.
• Robust current handling — Specified ripple current values at both low and high frequencies allow reliable operation under heavy AC stress and switching environments.
• Screw terminal reliability — Heavy‑duty terminal design simplifies high‑current wiring and provides a durable mechanical and electrical connection for long‑service systems.
• Designed for continuous thermal stress — 2000 hours endurance at 85°C under rated ripple current reflects suitability for sustained high‑temperature operation within the specified range.
• Regulatory compliance — RoHS compliance supports use in markets and products requiring restricted substance adherence.
