LNK2G822MSEH

The LNK2G822MSEH from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNK series, rated at 8.2 mF (8200 µF) and 400 V. Engineered for general‑purpose power applications, it delivers bulk energy storage and filtering with high ripple current capability and a long load life.

With a radial can screw‑terminal package (φ76.2 × 155 mm), RoHS compliance, and a rated operating range of −25 °C to 85 °C, this capacitor is suited to industrial and commercial equipment requiring high-voltage DC filtering and durable performance under continuous ripple stress.

Key Features

• High capacitance and voltage: 8.2 mF (8200 µF) nominal capacitance at a 400 V rating provides substantial bulk energy storage for DC‑link and smoothing applications.
• Screw terminal mounting: Radial can with screw terminals enables secure mechanical connection and straightforward installation or serviceability.
• High ripple current capability: Rated ripple current of 22.7 A at 120 Hz and 31.78 A at 10 kHz supports demanding AC ripple conditions on DC rails.
• Long load life： Designed for 5000 hours endurance at 85 °C under rated ripple current, providing predictable aging and lifecycle behavior.
• Operating temperature and stability: Specified for −25 °C to 85 °C with capacitance tolerance of ±20% (120 Hz, 20 °C) and tan δ of 0.2 for loss characterization.
• Leakage and safety attributes: Leakage current specified at up to 5000 µA; insulation resistance and voltage‑proof characteristics are defined in the LNK series datasheet.
• Physical package and packing: φ76.2 × 155 mm can with screw terminals; supplied in cardboard packing for mass production handling.
• Compliance: RoHS compliant per the product information provided.

Typical Applications

• Industrial power supplies: Bulk smoothing and energy storage on 400 V DC rails where high capacitance and ripple tolerance are required.
• Motor drives and inverters: DC‑link filtering and ripple absorption in commercial and industrial drive systems that operate within the specified temperature range.
• UPS and power conditioning systems: Energy buffering and transient support where long load life and high ripple current handling improve runtime stability.

Unique Advantages

• Substantial energy density: 8200 µF at 400 V reduces required capacitor count for bulk storage, simplifying board and cabinet design.
• High ripple handling: 22.7 A (120 Hz) and 31.78 A (10 kHz) ripple ratings allow the part to be used directly on heavily stressed DC buses without excessive temperature rise when used per datasheet conditions.
• Durability under load: 5000 hours endurance at 85 °C under rated ripple current gives predictable long‑term behavior for deployed systems.
• Serviceable terminations: Screw terminals offer robust electrical and mechanical connections for systems requiring maintenance or field replacement.
• Regulatory alignment: RoHS compliance supports deployment in regions with restricted substance requirements.
