LNY2G182MSEG

The LNY2G182MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNY series, designed for general-purpose power applications requiring high capacitance at elevated voltages. It combines a 1.8 mF (1800 µF) nominal capacitance with a 400 V rated voltage, a compact φ63.5 × 65 mm can, and screw-terminal mounting for robust electrical and mechanical connections.

Key value propositions include a 2000-hour load life at 85°C under rated ripple conditions, RoHS compliance, and rated performance across a –40°C to +85°C operating range—making it suitable where long endurance, high-voltage energy storage, and secure terminal connections are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing substantial energy storage for high-voltage circuits.
• Screw-Terminal Package — Radial can with screw terminals and M5 bolt nominal terminal hardware for secure, low-impedance connections and easy replacement or mounting.
• Endurance & Reliability — Load life of 2000 hours when rated ripple current is applied at 85°C; designed for sustained operation under specified ripple conditions.
• Ripple Current Performance — Rated ripple current of 9.1 A at 120 Hz and 12.74 A at 10 kHz, supporting typical AC ripple and higher-frequency filtering duties within the specified limits.
• Temperature Range & Stability — Operating temperature from –40°C to +85°C with impedance stability characterized to Z(–40°C)/Z(+20°C) = 12 for the 350–450 V range.
• Loss Characteristics — Specified tanδ (DF) of 0.25 and leakage current limited to the datasheet formula (3√CV µA or 5 mA, whichever is smaller) after 5 minutes at 20°C.
• Form Factor — Compact φ63.5 × 65 mm body (L: 6.5 cm × D: 6.35 cm) suitable for space-conscious equipment designs that require screw-terminal mounting.
• RoHS Compliant — Manufactured in compliance with RoHS directives referenced in the product documentation.

Typical Applications

• General-purpose power circuits — Used for energy storage, smoothing, and filtering in systems that require a 400 V, high-capacitance screw-terminal solution.
• Equipment requiring long endurance at elevated temperature — Suited where a 2000-hour load life at 85°C under rated ripple conditions is part of the design requirement.
• Systems needing secure terminal connections — Screw-terminal and M5-compatible hardware enable reliable electrical and mechanical connections in assemblies and chassis-mounted installations.

Unique Advantages

• High-voltage energy storage — 400 V rating combined with 1.8 mF capacitance delivers substantial stored energy for DC link, hold-up, or smoothing applications within the specified limits.
• Designed for sustained ripple loading — Explicit ripple current ratings at 120 Hz and 10 kHz and a 2000-hour endurance at 85°C provide predictable performance under continuous ripple stress.
• Robust mechanical termination — Screw-terminal construction with M5 nominal bolt compatibility simplifies mounting and replacement while maintaining low contact resistance.
• Broad operating temperature — Rated for –40°C to +85°C to accommodate a wide range of environmental conditions without exceeding specified performance limits.
• Regulatory compliance — RoHS compliance as stated in the product documentation supports environmental and regulatory requirements.
