LNY2W822MSEJ

The LNY2W822MSEJ is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNY series designed for high-capacitance, high-voltage applications. With a rated capacitance of 8.2 mF (8200 µF) at 450 V and a compact φ90×130 mm can, it targets general-purpose power electronics where bulk energy storage, smoothing and high ripple handling are required.

This part combines a wide operating temperature range (−40°C to +85°C), a 2000‑hour life at 85°C under rated ripple conditions, and robust screw‑terminal mounting to support reliable installation and serviceability in industrial equipment and power systems.

Key Features

• High Capacitance, High Voltage 8.2 mF (8200 µF) rated at 450 V for bulk energy storage and smoothing in high-voltage power rails.
• Screw Terminal Mounting Radial can with screw terminals provides a secure, serviceable connection suitable for heavy-current terminals and industrial assemblies.
• Long Endurance at Elevated Temperature Load life of 2000 hours at 85°C when subjected to DC plus rated ripple current, supporting sustained operation in warm environments.
• High Ripple Current Capability Rated ripple current of 20.1 A at 120 Hz and 28.14 A at 10 kHz, enabling effective suppression of AC ripple in power conversion and filtering applications.
• Wide Operating Temperature Range Specified operation from −40°C to +85°C for applications exposed to broad ambient conditions.
• Polarized Electrolytic Construction Polarized design suitable for DC energy storage and smoothing; capacitance tolerance ±20% (120 Hz, 20°C).
• RoHS Compliant Meets RoHS requirements, supporting regulatory compliance for assemblies.
• Compact, High‑Capacitance Can Physical size φ90×130 mm (approx. 9 × 13 cm) for high capacitance density in a relatively compact footprint.

Typical Applications

• Power Supply Filtering Bulk smoothing and decoupling on high-voltage DC rails where 450 V rating and high capacitance reduce ripple and improve regulator stability.
• Power Conversion DC link and energy-storage capacitor for inverters, rectifiers and industrial converters, leveraging high ripple current capability.
• Industrial Electronics Energy buffering and smoothing in industrial control cabinets and power modules that require durable screw‑terminal connections and extended life at elevated temperature.

Unique Advantages

• High Energy Density: 8.2 mF at 450 V provides significant stored energy in a single component to minimize parts count for bulk storage.
• Robust Termination: Screw terminals deliver secure, low‑impedance connections suitable for high-current installations and easier field replacement.
• Designed for Continuous Use at Elevated Temperature: 2000‑hour rated life at 85°C under ripple load supports reliable long‑term operation in warm enclosures.
• Effective Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz accommodate a range of switching and line‑frequency conditions.
• Wide Ambient Range: −40°C to +85°C rating enables deployment across varied environmental conditions without derating in typical industrial settings.
• Regulatory Compliance: RoHS compliance helps streamline inclusion in regulated product lines.
