LNY2V103MSEJ

The LNY2V103MSEJ from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNY series, offering 10,000 µF capacitance at 350 V in a high-capacitance radial can package (φ90 × 95L). It is designed for general-purpose power applications where compact bulk energy storage and high ripple handling are required.

Key value propositions include a screw-terminal package for robust connections, long-load life under ripple conditions, and suitability for equipment downsizing thanks to its high capacitance density.

Key Features

• Capacitance & Voltage — 10,000 µF rated capacitance with a 350 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing substantial bulk storage for DC bus and smoothing applications.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance power connections suitable for high-current bus installations.
• High Ripple Current Capability — Rated ripple current of 23.5 A at 120 Hz and 32.9 A at 10 kHz to support demanding AC ripple conditions.
• Load Life & Endurance — Designed to meet load-life requirements with rated ripple current applied for 2000 hours at 85°C, then restored to 20°C to meet endurance criteria detailed in the LNY series datasheet.
• Operating Temperature Range — Specified for –40°C to +85°C operation, with low-temperature stability (impedance ratio Z(−40°C)/Z(+20°C) up to 12).
• Leakage, Insulation & Voltage Proof — Leakage current after 5 minutes at rated voltage is specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V voltage proof for 1 minute between terminal and bracket.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Form Factor — Physical footprint L: 9.5 × D: 9 cm (φ90 × 95L) for higher capacitance in a compact screw-terminal can.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing for high-voltage DC rails, leveraging 10,000 µF at 350 V to stabilize bus voltage under load transients.
• Industrial Power Systems — DC link and energy buffer in industrial inverters and drives where robust screw-terminal connections and high ripple capability are required.
• UPS and Power Conversion — Energy reservoir and ripple suppression in uninterruptible power supplies and large converters operating up to 350 V.

Unique Advantages

• High Bulk Energy Density: 10,000 µF at 350 V supplies significant capacitance per package to reduce the number of parallel components required.
• Robust Power Connections: Screw-terminal radial can package enables secure mechanical and electrical connections for high-current installations.
• Engineered for Ripple Endurance: Rated ripple currents (23.5 A at 120 Hz, 32.9 A at 10 kHz) and a 2000-hour load-life at 85°C demonstrate suitability for sustained ripple environments.
• Wide Temperature Range with Low-Temp Stability: –40°C to +85°C operation and an impedance ratio of up to 12 at −40°C help maintain performance across environmental extremes.
• Electrical Safeguards: Specified leakage current limits, high insulation resistance, and AC 2500 V voltage proof between terminal and bracket support reliable installation and safety validation.
• RoHS Compliance: Conforms to RoHS directives, facilitating integration into systems targeting restricted-substance compliance.
