LNY2W182MSEGBN

The LNY2W182MSEGBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose applications requiring high-voltage bulk capacitance. It delivers 1.8 mF at a 450 V rating with a compact φ63.5 × 75 mm can and screw-terminals for secure mechanical and electrical connections.

Engineered for equipment downsizing and reliable operation, this part offers a 2,000-hour load life at 85°C, broad operating temperature range, and RoHS compliance, making it suitable for a variety of industrial and power system designs that need high-voltage energy storage in a robust package.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) rated at 450 V for high-voltage bulk energy storage.
• Screw-Terminal Mounting: Radial can with screw terminals and M5 bolt nominal diameter for secure, serviceable connections and straightforward mounting.
• Compact Mechanical Profile: Dimensions approximately 7.5 × 6.35 cm (L × D) with a φ63.5 mm diameter, enabling higher capacitance in a relatively small footprint for its class.
• Temperature Range and Life: Rated for −40°C to +85°C operating range with a guaranteed load life of 2,000 hours at 85°C under rated ripple conditions.
• Ripple Current Capability: Rated ripple current of 8.9 A at 120 Hz and 12.46 A at 10 kHz, supporting applications with significant AC ripple on DC bus lines.
• Leakage and Insulation: Leakage current specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand: No abnormality under AC 2500 V for 1 minute between terminal and bracket, providing assurance of dielectric integrity in the assembly.
• RoHS Compliant: Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose equipment: Provides bulk energy storage and smoothing for systems classified as general purpose, where 450 V rated capacitance is required.
• Equipment downsizing: Higher capacitance in a compact screw-terminal can makes it suitable for designs aiming to reduce overall system size while retaining energy storage capacity.
• High-voltage DC systems: Use in 350–450 V environments where stable capacitance and ripple handling are needed across −40°C to +85°C operating conditions.

Unique Advantages

• High-voltage, high-capacitance combination: 1.8 mF at 450 V supplies substantial energy storage for high-voltage rails without moving to larger diameter packages.
• Screw-terminal reliability: Screw terminals (M5 nominal bolt) and a radial can simplify secure installation and maintenance in field-assembled or serviceable designs.
• Rated ripple performance: Defined ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) enable predictable thermal and electrical behavior under real ripple loads.
• Durability under elevated temperature: 2,000-hour endurance at 85°C with rated ripple current provides a measurable life expectation for thermal-stressed applications.
• Electrical integrity safeguards: Leakage current limits, high insulation resistance, and a 2,500 V AC voltage-proof between terminal and bracket support reliable long-term operation and safety margins.
• Regulatory compliance: RoHS compliance assists with regulatory and supply-chain requirements for restricted substances.
