LNY2W182MSEFBB

The LNY2W182MSEFBB is an aluminum electrolytic, screw-terminal capacitor providing 1.8 mF capacitance at a 450 V rating in a radial can with screw terminals. It is designed for general-purpose high-voltage DC applications and is part of Nichicon’s LNY series offering higher capacitance in screw-terminal packages.

Key value propositions include a broad operating temperature range (−40 °C to +85 °C), a rated load life of 2000 hours at 85 °C under ripple conditions, RoHS compliance, and rated ripple-current performance suitable for demanding power circuits.

Key Features

• Capacitance and Voltage — 1.8 mF (1800 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Screw Terminal Mounting — Radial can package with screw terminals and M5 bolt compatibility for robust, low-inductance connections in high-voltage assemblies.
• Operating Temperature and Lifetime — Rated for −40 °C to +85 °C with a load life specification of 2000 hours at 85 °C when subjected to rated ripple current.
• Ripple Current Capability — Specified ripple current: 7.9 A at 120 Hz and 11.06 A at 10 kHz, supporting high-stress DC filtering and smoothing tasks.
• Leakage and Insulation — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance of more than 100 MΩ at DC 500 V between terminal and bracket.
• Endurance and Voltage Proof — Endurance defined by recovery to 20 °C after DC plus rated ripple-current application for 2000 hours at 85 °C; voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Regulatory — RoHS compliant per the provided product information.
• Physical — Body dimensions: 95 mm length × 51 mm diameter (φ51 × 95L) in a radial can with screw terminals; cardboard packing for mass production delivery.

Typical Applications

• General-purpose power circuits — Suitable where a high-voltage, high-capacitance screw-terminal capacitor is required for DC applications within the rated voltage and temperature envelope.
• Equipment downsizing — Part of the LNY series designed to provide higher capacitance in screw-terminal packages, helping designers consolidate capacitance in compact assemblies.
• High-voltage DC systems — Use in DC systems up to the 450 V rating for bulk energy storage, filtering, or smoothing where screw-terminal mounting is preferred.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage DC applications without series stacking of capacitors.
• Long rated life at elevated temperature: 2000 hours at 85 °C under rated ripple conditions provides predictable endurance for designs exposed to thermal stress.
• Robust screw-terminal connections: M5-compatible screw terminals and radial can packaging simplify secure mounting and high-current connections.
• Measured ripple performance: Specified ripple current at both low and high frequencies (7.9 A at 120 Hz; 11.06 A at 10 kHz) lets engineers size the part based on measured ripple loads.
• Verified electrical safeguards: Defined leakage current limits, insulation resistance >100 MΩ at DC 500 V, and AC 2500 V dielectric proof provide verifiable electrical durability.
• Regulatory compliance: RoHS compliance supports use in regions and projects requiring restricted-substance conformity.
