LNT2W822MSEJ

The LNT2W822MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series. It provides high capacitance (8.2 mF) at a 450 V rating in a radial can with screw terminals, designed for general-purpose power applications that require bulk energy storage and high-voltage smoothing.

Key value propositions include a 5000‑hour rated life at 105°C, robust screw-terminal mounting for secure electrical and mechanical connections, and high ripple current handling across low and high frequencies.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable where high-voltage bulk capacitance is required.
• Thermal Endurance — Rated operating temperature range of −25°C to +105°C with a load life of 5000 hours at 105°C, providing predictable long-term behavior under elevated temperature stress.
• High Ripple Current — Supports 32.5 A ripple current at 120 Hz and 45.5 A at 100 kHz, enabling reliable performance under AC ripple and switching conditions.
• Electrical Loss & Leakage — Specified tanδ of 0.2 and a leakage current rating of 5000 µA, giving clear electrical-loss and leakage parameters for design verification.
• Rugged Mounting & Package — Screw terminal, radial can package (φ90×190L form factor; size L: 19 × D: 9 cm) for secure bolted connections and easy integration into high-current power assemblies.
• Compliance & Production — RoHS compliant, supplied in cardboard packing, and available for mass production runs.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing in high-voltage DC supply rails, leveraging 8.2 mF at 450 V and high ripple current capability.
• Industrial inverters and drives — DC-link and smoothing capacitor applications where elevated temperature endurance (105°C) and long life (5000 h) support continuous operation.
• Large-format switching supplies — Filtering and energy buffering in high-power switching topologies that require robust screw-terminal connections and high ripple handling at both 120 Hz and 100 kHz.

Unique Advantages

• High-voltage, high-capacitance in one component: 8.2 mF at 450 V provides significant bulk energy storage in a single radial can, simplifying DC-link and smoothing design.
• Designed for continuous elevated-temperature operation: 5000 hours of load life at 105°C supports long-term reliability in thermally demanding environments.
• Robust electrical and mechanical termination: Screw terminals enable secure, low-resistance connections for high-current installations and simplified field installation/maintenance.
• Clear performance limits for design confidence: Defined tanδ, leakage current, and ripple current specs (at both 120 Hz and 100 kHz) allow engineers to verify margins against actual operating conditions.
• Production-ready packaging: Supplied in cardboard packing and available for mass production, easing procurement and assembly logistics.
• Regulatory compliance: RoHS compliant to support environmentally restricted designs.
