LNY2W822MSEJBN

The LNY2W822MSEJBN is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for high‑capacitance, high‑voltage general‑purpose applications. With an 8200 µF (8.2 mF) nominal capacitance and a 450 V rating, it targets equipment designs that require bulk energy storage and robust terminal connections.

Engineered for equipment downsizing and reliable field operation, this part delivers rated performance across –40 °C to +85 °C, a 2000‑hour load life under ripple current at 85 °C, and RoHS compliance.

Key Features

• Capacitance & Voltage: 8.2 mF (8200 µF) nominal capacitance with a 450 V rated voltage for high‑voltage bulk energy storage.
• Package & Mounting: Radial can with screw terminals (screw terminal type) for secure, low‑impedance mechanical and electrical connections.
• Temperature Range: Rated for operation from –40 °C to +85 °C to support a wide range of ambient conditions.
• Endurance: Load life of 2000 hours when subjected to rated ripple current at 85 °C, per manufacturer specification.
• High Ripple Current Capability: 20.1 A at 120 Hz and 28.14 A at 10 kHz, supporting demanding AC ripple conditions.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage is limited to 3√(C·V) µA or 5 mA, whichever is smaller (measurement at 20 °C).
• Capacitance Tolerance: ±20% (120 Hz, 20 °C), allowing predictable sizing for decoupling and smoothing functions.
• Size & Form Factor: Compact radial can design with dimensions L: 13 × D: 9 cm and a seated height up to 5.118 inches to support power‑dense layouts.
• RoHS Compliant: Meets directive requirements (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• General Purpose Equipment: Provides bulk capacitance for smoothing and energy storage in industrial and commercial systems where a high‑voltage, high‑capacitance solution is required.
• Power Supply Filtering: Suited for DC bus smoothing and ripple mitigation in power conversion equipment that uses screw‑terminal connections for robust mounting.
• Equipment Downsizing Projects: Designed to support smaller power assemblies by delivering high capacitance per package to help reduce overall system volume.

Unique Advantages

• High Voltage, High Capacitance Combination: 8200 µF at 450 V enables significant energy storage in a single component, reducing the number of parallel parts required.
• Robust Screw‑Terminal Interface: Provides secure electrical and mechanical connections suited for higher current and serviceable installations.
• Designed for Continuous Ripple Duty: Specified ripple current ratings at both 120 Hz and 10 kHz support applications with sustained AC ripple stress.
• Extended Endurance at Elevated Temperature: Rated 2000 hours under rated ripple at 85 °C to support longer operational life in warm environments.
• Predictable Leakage Behavior: Leakage current defined by a clear formula (3√(C·V) µA or 5 mA), helping engineers size bleed and balancing networks accurately.
• Regulatory Compliance: RoHS conformity reduces material‑restriction risks for commercial designs.
